Error "positive position limit".
The positive position limit (C1223) was exceeded, potentially due to incorrect position targets or issues with the 'set function position value'. This can cause the drive to overtravel its intended positive extreme.
No reference.
The reference point for the drive is not known. In absolute positioning mode, homing was not performed before the first positioning command, which is essential for establishing a known position.
Parameter set mode is absolute instead of relative.
An absolute parameter set (C1311) was performed or is active during relative positioning (position mode C1210). This mismatch in positioning modes prevents correct operation.
Error "actual reference dimension offset".
The actual reference dimension offset (C1226) is outside the defined position limits. This indicates an error with the program function 'set position value' or incorrect limit settings.
Error in positioning program.
The positioning program contains impermissible programming. Specifically, a parameter set with a final speed must be followed by a parameter set with positioning, and it is not permissible to wait for input at that stage.
Error in the range of the encoder.
The traversing range of the absolute encoder has been exceeded. This means the physical travel of the drive has gone beyond the measurement capabilities of the installed encoder.
Fieldbus Motor Phase Failure (Warning)

BUS-OFF state of system bus (CAN)
The controller has received too many faulty telegrams via the system bus (CAN) and has disconnected from the bus. This indicates a severe communication issue on the CAN network, preventing data exchange.
CAN Time-Out
A CAN communication timeout has occurred. This could be due to a slave device not responding during remote parameterization (C0370), incorrect parameter set changeover configuration with application I/O, or an internal error with a module on the FIF. A communication timeout means commands or data are not being exchanged, leading to operational halts or incorrect behavior.
CAN Module Warning/Bus-Off
The CAN function module on the FIF has reported a 'Warning' or 'Bus-Off' status, indicating underlying communication issues. This often points to problems with bus termination, cable shielding, PE connection, or an overloaded bus. While 'Warning' might allow limited operation, 'Bus-Off' will completely halt communication.
CAN Remote Parameterization Error
A communication error has occurred during remote parameterization via the system bus (C0370), typically because a node is unresponsive or unavailable. This can also be caused by incorrect parameter set changeover configuration with application I/O. Such errors prevent remote configuration and control of the drive.
Earth fault
The drive system includes protective measures against earth faults, though to a limited extent, as per EN 61800-5-1. This fault indicates current leakage to ground, posing risks of electrical shock and equipment damage. Fault acknowledgement is necessary to clear this condition and resume operation.
External Fault (TRIP-SET)
An external disturbance has been detected, activating a digital signal assigned to the TRIP-SET function (DCTRL1-TRIP-SET). This typically results from a LOW level at the signal source for this function, causing the controller to inhibit. Ignoring this can lead to system shutdown and operational delays.
Keypad/Device Communication Abort
A communication abort has occurred between the keypad and the standard device (e.g., fault codes ErP0 through ErP19), indicating a failure in data exchange. The specific cause can vary. This prevents proper interaction with the device via the keypad and requires expert assistance for diagnosis.
Fan Failure
The cooling fan, particularly in 8200 motec controllers (3...7.5 kW), has either failed or is disconnected. This condition can lead to the controller overheating, potentially causing thermal shutdown and reducing the lifespan of internal components if not addressed promptly.
Initialization or Communication Error
This status indicates an initialization error or a communication error between the keypad and the controller. It signifies that the drive controller is unable to properly start up or establish communication with its human-machine interface.
Internal Fault

The sensor for detecting the heatsink temperature is indicating undefined values. This prevents accurate monitoring of the heatsink's thermal status, potentially leading to overheating if not addressed.
Internal controller temperature sensor error
The sensor for detecting the internal temperature of the controller is indicating undefined values. This prevents accurate monitoring of the internal component temperature, risking damage from overheating.
Parameter Identification Fault
The motor parameter identification process has failed, most likely because the motor is not properly connected to the drive. Incorrect parameter identification can lead to suboptimal motor control, instability, and potential damage to both the motor and the drive if not resolved.
Motor Phase Interruption Monitoring
Monitoring of motor phases (LP1) does not respond to an interrupted motor phase, even if C0597 = 0 or 2, because the MLP1 function block is not entered into the processing table. This means an interrupted motor phase will not be detected.
Undervoltage in the DC bus
The DC bus voltage is lower than the value specified in C0173. This indicates insufficient input power to the drive, potentially due to issues with the mains voltage or supply cabling, preventing proper drive operation.
Motor Overtemperature
The drive system provides protection against motor overtemperature, specifically monitored using an I²xt-monitoring function. This feature safeguards the motor from thermal damage caused by prolonged overload or inadequate cooling, triggering a fault when internal temperature limits are exceeded.
Speed control error
The motor speed is out of the tolerance margin defined by C0576. This typically occurs due to an excessively high active load (e.g., in hoists) or mechanical blockades, preventing the drive from achieving the commanded speed.
Maximum system speed exceeded
The maximum system speed, set by C0596, has been exceeded. This can be caused by an active load that is too high, the drive not being speed-controlled, or an excessively limited torque, leading to overspeed conditions.
Output Short Circuit
A short circuit has been detected on the drive's output, possibly in the motor, motor cables, or brake resistor circuit. Excessive capacitive charging current from long or high-capacitance motor cables can also falsely trigger this fault. An unresolved short circuit poses a severe risk of damage to the drive's output stage.
Motor cable earth fault
One of the motor phases has earth contact, indicating an insulation fault in the motor cable or motor windings. This presents a safety risk and can cause drive damage.
Controller Overload (Acceleration)
The controller has experienced an overload condition during acceleration, possibly due to an acceleration time (C0012) that is too short, an improperly dimensioned drive, or issues with the motor/cabling like a defective motor cable or interturn fault. Persistent overloading can lead to drive component degradation and premature failure.
Controller Overload (Deceleration)
The controller has overloaded during deceleration, often because the deceleration time (C0013) is set too short or the external brake resistor is inadequately dimensioned. Excessive regenerative energy not properly dissipated can damage the drive's DC bus components and lead to overvoltage faults.
Controller Overload (Steady-State)
The controller is experiencing frequent or prolonged overload periods during steady-state operation, indicating the drive is undersized for the continuous load. Continuous operation beyond the drive's rated capacity will lead to overheating and significantly reduce its lifespan, potentially causing premature failure.
Motor Overload (I²t)
The motor has exceeded its thermal overload limit (I²t model), caused by excessive continuous current or frequent/prolonged acceleration cycles. This indicates the motor is either undersized for the application, or the drive parameters are not correctly configured. Continued operation under overload conditions will severely damage the motor windings.
I²xt overload advance warning
This is an advance warning for a potential I²xt overload, indicating frequent and prolonged acceleration processes with motor overcurrent or permanent motor overload with Imotor > Irmotor. It suggests that conditions are approaching a trip threshold.
Heatsink Overtemperature Warning
The drive has detected a heatsink overtemperature condition. This is a warning that indicates the heatsink temperature has exceeded its normal operating range, but the drive continues to operate in a controlled manner.
Motor Overtemperature (PTC TRIP)
The motor's PTC thermistor has detected an overtemperature condition, triggering a TRIP fault. This is usually caused by the motor operating under impermissible high currents or frequent/long acceleration processes, or simply if the PTC sensor is not connected while monitoring is active (C0119 = 1 or 4). Continued motor operation in an overtemperature state will lead to severe winding damage and premature motor failure.
Controller Overtemperature (Internal)
The controller's internal temperature has exceeded its safe operating limit. This indicates that the controller is experiencing excessive load, has insufficient cooling, or its internal fan is failing. Sustained internal overtemperature will lead to derating, thermal shutdown, and reduced lifespan of internal components.
Motor overtemperature (C0121)
The motor temperature, detected via resolver or incremental encoder, has exceeded the threshold set in C0121. This indicates thermal overload from impermissible continuous current, frequent/prolonged acceleration processes, or the C0121 value being set too low.
Motor overtemperature (T1/T2)
The motor temperature, measured via inputs T1 and T2, is too high. This signifies thermal overload due to impermissible continuous current or frequent/prolonged acceleration processes. It can also occur if terminals T1 and T2 are not connected to a PTC/temperature contact.
PTC Monitoring
The drive has triggered the PTC monitoring function. This indicates that the Positive Temperature Coefficient (PTC) thermistor, likely in the motor, has exceeded its threshold temperature, signifying an overtemperature condition. The drive continues to operate in a controlled manner.
Overvoltage during DC-injection braking
An overvoltage (OU) TRIP occurs if, during DC-injection braking (GSB) at high motor speeds, the residual voltage from magnetism and high speed generates an excessive motor current. This can lead to overvoltage due to the drive's attempt to reduce magnetization when the pulse inhibit (DCTRL-IMP) is too short.
DC Bus Overvoltage (Braking/Earth Leakage)
An overvoltage condition has occurred, specifically related to braking operations or an earth leakage at the motor end. During braking, insufficient deceleration time or an undersized/defective brake resistor can cause this. An earth leakage in the motor or cable also contributes. This fault indicates high stress on the drive's DC bus, potentially leading to component failure.
Following error
The angle difference between the set and actual position is larger than the following error limit set under C0255. This indicates that the drive cannot accurately follow the commanded position or speed, possibly due to insufficient torque or excessive load.
Angle overrun
The phase controller limit has been reached, meaning the drive cannot follow the digital frequency due to hitting its Imax limit. This indicates the drive is being commanded beyond its current capability, potentially causing instability.
CAN sync telegram transfer error
The sync telegram from the master (PLC) is out of sync cycle or not received, indicating a communication issue. This can also occur if the controller is enabled too fast, before the sync telegrams are stable.
Input values at X9 are limited
The function block DFIN is limiting the input values at X9, which causes a loss of increments. This suggests an issue with the digital frequency connection or a mismatch in master/slave settings, affecting precise control.
Program error
An error has been detected in the program flow of the device. This signifies an internal software issue that prevents normal operation.
Fault during parameter initialisation
An error was detected during the parameter set transfer between two devices, or the parameter set does not match the controller (e.g., if data was transferred from a higher-power controller to a lower-power controller). This can lead to incorrect drive configuration.
Error during rotor position adjustment
The rotor position adjustment process was cancelled, often because an Sd7 or Sd8 error occurred during adjustment with an absolute value encoder. Without a successfully executed rotor position adjustment, the drive may carry out uncontrolled movements.
Defective All Parameter Sets
All parameter sets within the controller have become defective, often due to an interrupted or faulty parameter transfer from the keypad. This critical issue prevents the drive from operating correctly as its configuration is lost or corrupted. Operating with corrupted parameters can lead to unpredictable behavior and potential damage.
Error in parameter set
This error occurs when the operating system software has been updated and requires the storage of the Lenze setting to ensure compatibility. This typically happens after a firmware upgrade.
Checksum error in parameter set 1
A fault occurred when loading parameter set 1, which could be due to an interruption during transmission via the keypad or incompatibility between the stored parameters and the loaded software version. The Lenze setting is loaded automatically.
Defective Parameter Set 2
Parameter set 2 within the controller has become defective, likely due to an interrupted or faulty transfer from the keypad. This indicates a corruption in a specific configuration set, which can prevent proper drive operation when that set is active. Operating with corrupted parameters can lead to unpredictable behavior.
Defective Parameter Set 3
Parameter set 3 within the controller has become defective, likely due to an interrupted or faulty transfer from the keypad. This indicates a corruption in a specific configuration set, which can prevent proper drive operation when that set is active. Operating with corrupted parameters can lead to unpredictable behavior.
Defective Parameter Set 4
Parameter set 4 within the controller has become defective, likely due to an interrupted or faulty transfer from the keypad. This indicates a corruption in a specific configuration set, which can prevent proper drive operation when that set is active. Operating with corrupted parameters can lead to unpredictable behavior.
Internal Fault (EEPROM)
An internal fault related to the EEPROM (Electrically Erasable Programmable Read-Only Memory) has been detected, indicating a defect in the controller's non-volatile memory. This is a critical hardware failure that can lead to data loss and system malfunction. This fault requires manufacturer intervention.
Parameter Transfer Time Error
A time error occurred during parameter set transfer, meaning the data flow from the keypad or PC was interrupted (e.g., keypad removed). This incomplete transfer can leave parameters in an undefined state, preventing correct operation. Operating with partially transferred parameters can cause erratic and dangerous behavior.
Auto-TRIP Reset Error (Counter Exceeded)
This fault indicates that the controller has attempted and failed to perform more than eight automatic TRIP resets within a 10-minute period. It signifies a persistent underlying fault condition that repeatedly triggers and attempts to reset, but the root cause is not being resolved. Ignoring this means an underlying problem is not being addressed, leading to repeated shutdowns and potential drive wear.
Resolver error at X7
The resolver cable connected to X7 is interrupted, or the resolver itself is faulty. This prevents accurate motor position feedback, which is crucial for precise motor control.
Encoder error at X9
The encoder cable connected to X9 is interrupted, or pin X9/8 is not connected (input signal 'Lamp Control' at X9/8 is LOW). This leads to a loss of encoder feedback, which can cause uncontrolled drive movements if not addressed.
Encoder error at X6/1 and X6/2
The current signal at analog input X6/1 and X6/2 is less than 2mA, indicating an issue with the encoder or its wiring. This monitoring is only possible if C0034 = 1, and its failure means loss of accurate position feedback.
Motor temperature sensor error
The encoder for detecting the motor temperature at X7 or X8 is indicating undefined values. This prevents proper motor thermal protection and could lead to motor damage due to overheating.
Absolute value encoder initialisation error at X8
The absolute value encoder at X8 has an initialisation error, is defective, or is not sending data. This may also occur if the encoder constant (C0420) for C0025=309 is altered. An uninitialised encoder can lead to uncontrolled drive movements.
SinCos encoder error at X8
The SinCos encoder at X8 is sending inconsistent data, indicating damaged tracks, high interference levels on the cable, or an open circuit. It could also be due to an incorrect encoder type or improperly set supply voltage.
Short circuit
The drive system includes protective measures against short circuits, though to a limited extent, as per EN 61800-5-1. This fault indicates an abnormal current path, potentially causing excessive current flow and damage to internal components or connected wiring. Fault acknowledgement is necessary to clear this condition and resume operation.
OC8 I²xt overload advance warning
This is an advance warning indicating frequent and excessively long acceleration processes with motor overcurrent, or permanent motor overload where the motor current (Imotor) exceeds the rated motor current (Irmotor). This condition suggests that the drive or motor dimensioning may be inadequate, and continuous operation without addressing it could lead to an OC6 trip. This warning is managed by parameter C0606.
LP1 Motor phase failure
One of the current-carrying motor phases has failed. This monitoring function is primarily for asynchronous motors and requires the MLP1 function block to be entered in C0465. Possible causes include a faulty motor, a damaged motor cable, or a current limit value (C0599) set too low. The monitoring can be switched off via C0597.
OH3 Motor temperature > +150°C threshold
The motor temperature has exceeded the +150°C threshold, detected via resolver or incremental value encoder (e.g., KTY sensor at X8/5, X8/8). This indicates the motor is thermally overloaded due to impermissible continuous current or frequent/long acceleration processes. This monitoring can be switched off via C0583.
OH4 Heatsink temperature > C0122
The heatsink temperature has exceeded the specific threshold value set in parameter C0122. This is an advance warning for heatsink overheating, which can be caused by high ambient temperatures (Tu > +40°C or +50°C), a dirty heatsink, or an incorrect mounting position. This monitoring can be switched off via C0582.
OH7 Motor temperature > C0121
The motor temperature has exceeded the specific threshold value set in parameter C0121, detected via resolver or incremental value encoder. This indicates the motor is thermally overloaded due to impermissible continuous current or frequent/long acceleration processes. This is an advance warning for motor overheating. This monitoring can be switched off via C0584.
OH8 Motor temperature via inputs T1 and T2 is too high
The motor temperature is too high, detected by a PTC or temperature contact connected to terminals T1 and T2. This indicates motor thermal overload due to impermissible continuous current or frequent/long acceleration processes. The fault can also occur if terminals T1 and T2 are not correctly connected to a temperature sensor. This monitoring can be switched off via C0585.
CE0 Communication error on the automation interface (AIF)
A communication error has occurred on the automation interface (AIF). This indicates a problem with the physical communication link, its configuration, or the communication master. This error is managed by parameter C0126.
CE1 Communication error at process data input object CAN1_IN
A communication error has occurred with the process data input object CAN1_IN. This can be due to issues with the CAN bus, wiring, or incorrect data configuration. The monitoring time for this communication channel can be set with parameter C0357/1.
CE2 Communication error at process data input object CAN2_IN
A communication error has occurred with the process data input object CAN2_IN. This can be due to issues with the CAN bus, wiring, or incorrect data configuration. The monitoring time for this communication channel can be set with parameter C0357/2.
CE3 Communication error at process data input object CAN3_IN
A communication error has occurred with the process data input object CAN3_IN. This can be due to issues with the CAN bus, wiring, or incorrect data configuration. The monitoring time for this communication channel can be set with parameter C0357/3.
CE4 BUS-OFF state of the system bus (CAN)
The system bus (CAN) has entered a BUS-OFF state due to an excessive number of faulty telegrams. This indicates a severe and persistent communication problem on the CAN network, which is configured via parameter C0595.
Sd3 Interruption of the digital frequency coupling
The input signal 'Lamp Control' at terminal X9/8 is LOW, indicating an interruption of the digital frequency coupling. If the response (C0587) is set to 'Warning' (2), continued operation without addressing this fault can potentially damage the drive.
Sd5 Analog input current < 2 mA
The input current at analog input X6/1 or X6/2 has fallen below 2 mA. This monitoring function is only active if parameter C0034 is set to 1, indicating a low current condition on the analog input.
Sd6 Thermal sensor error at motor (X7 or X8)
An error has been detected with the thermal sensor connected to the motor inputs X7 or X8. This indicates a malfunction of the sensor itself or an issue with its wiring, preventing accurate motor temperature monitoring. This monitoring is controlled by parameter C0594.
EEr External monitoring (activated via DCTRL)
An external monitoring function has triggered this fault, which is activated via DCTRL (Drive Control) and configured through parameter C0581. The 'x' in the code indicates the response type: 0 for TRIP, 1 for message, 2 for warning.
H10 Thermal sensor error at heatsink
An error has been detected with the thermal sensor responsible for monitoring the heatsink temperature. This indicates a fault with the sensor itself or its wiring, compromising the heatsink temperature monitoring. This monitoring is controlled by parameter C0588.
H11 (Temperature sensor error: Temperature inside the controller)
The internal temperature sensor within the controller is reporting undefined values. This compromises the ability of the drive to monitor and protect itself against overheating conditions.
CAN Sync Telegram Error
An incorrect transmission of the synchronization telegram (displayed as P16) has occurred on the CAN system bus. This internal fault, related to C1290, indicates an issue with the timing or integrity of CAN communication synchronization, which can lead to unstable multi-axis operation.
NMAX (Maximum system speed exceeded)
The maximum system speed (defined by C0596) has been exceeded. This typically occurs due to an excessively high active load, such as in hoist applications, or if the drive is not speed-controlled and torque limits are too low, allowing overspeed.
CDA
An attempt was made to transmit profile data that was detected as faulty. This typically occurs during communication processes involving profile data transfer, indicating data integrity issues.
CDA-LOAD
A checksum error was detected for the transferred profile data, indicating corruption or an incomplete transfer. This means the integrity of the loaded profile data is compromised and may lead to incorrect operation.
ovrTrans Queue
The transmit request memory has overflowed, indicating too many CAN objects are queued for transmission. This can lead to delays or loss of communication on the system bus.
ovr Receive
Too many receive telegrams are present on the system bus (CAN). This overload can cause issues with processing incoming communication data, potentially leading to lost messages or communication delays.
2.Flash Err
An error occurred during access to the FLASH memory, indicating the PLC program attempted to access non-available or defective memory. This could signify a hardware issue with the FLASH memory module, preventing proper program execution or data storage.
AddData CsErr
A checksum error occurred when loading data into the FLASH memory. This indicates data corruption during the transfer process to non-volatile memory, which can lead to incorrect program behavior or lost settings.
