A short circuit has occurred in the motor cable, or there is excessive capacitive charging current if the motor cable is too long or has high capacitance. This can lead to drive tripping and potential damage.
OC2
One of the motor phases has made contact with earth (ground), indicating an earth fault. This suggests an insulation breakdown in the motor cable or the motor windings.
OC5
The drive is experiencing an I x t overload, characterized by frequent and excessively long acceleration phases with overcurrent, or continuous overload where Imotor > 1.05 x Irx. This indicates that the drive is undersized for the application.
OC6
The drive is experiencing an I²xt overload, characterized by frequent and excessively long acceleration processes with motor overcurrent, or permanent motor overload where Imotor > Irmotor. This signals a prolonged motor overload condition.
I²xt overload advance warning
This is an advance warning for an I²xt overload, indicating frequent and excessively long acceleration processes with motor overcurrent, or permanent motor overload where Imotor > Irmotor. It signals an impending trip condition if conditions do not change.
float Sys-T
A float error, such as division by zero, has occurred in the system task (ID 0) during real number calculations. This indicates an issue within the program code's arithmetic operations, leading to an imprecise or undefined result.
float Cycl.-T
A float error, such as division by zero, has occurred in the cyclic task (PLC_PRG ID 1) during real number calculations. This indicates an issue within the PLC program's arithmetic operations that impacts the cyclic execution.
float Task1
A float error, such as division by zero, has occurred in task 1 (ID 2) during real number calculations. This indicates an issue within the program code specific to task 1's arithmetic operations.
float Task8

overrun Cyc.-T
The cyclic task (PLC_PRG ID 1) has exceeded its allocated monitoring time. This indicates that the task processing duration is longer than the set monitoring time, potentially due to complex or lengthy program parts.
noT-Fkt Credit
The controller lacks the necessary technology units to execute a loaded program containing technology functions. This indicates a mismatch between the program's requirements and the controller's hardware capabilities.
No Program
No PLC program has been loaded into the controller's memory. The controller is unable to execute any programmed logic or control functions without a loaded program.
Unallowed Lib
The PLC program attempted to call a library function that is not supported by the current controller hardware or firmware. This means a required hardware component might be missing, or the function is incompatible with the controller variant.
NoCam Data
Motion profiles (CAM data) are not available in the controller's memory, despite functions from the `LenzeCamControl.lib` library being called. This prevents motion control functions from operating correctly, potentially due to incorrect project setup or a reset.
LP1
A current-carrying motor phase has failed, or the current limit value is set too low. This can lead to irregular motor operation, reduced performance, or motor damage.
OH
The heatsink temperature has exceeded +90°C. This is often caused by an ambient temperature greater than +40°C or +50°C, a dirty heatsink, or an incorrect mounting position, leading to potential overheating.
CE4
The controller has entered a BUS-OFF state on the system bus (CAN) due to receiving too many faulty telegrams, leading to disconnection from the bus. This indicates a severe communication breakdown.
CE5
A time-out has occurred on the system bus (CAN) during remote parameterization (C0370, C0371), indicating a communication error of the gateway function. The slave device did not respond within the communication monitoring time.
U15
The internal 15V voltage supply is experiencing an undervoltage condition. This affects the internal control electronics and can prevent proper device operation.
CCr
A system failure has occurred due to strong interference injection on the control cables. This can be caused by inadequate shielding or ground/earth loops in the wiring, leading to unstable operation.
PR1
A checksum error was detected in parameter set 1 during loading or transfer via the keypad. This indicates a fault in the parameter data or incompatibility with the loaded software version. The Lenze default settings are loaded automatically.
PR2
A checksum error was detected in parameter set 2 during loading or transfer via the keypad. This indicates a fault in the parameter data or incompatibility with the loaded software version. The Lenze default settings are loaded automatically.
PEr
An error has occurred in the program flow, indicating an internal software issue within the device. This may lead to unexpected behavior or system stoppage.
PR0
An error exists in the parameter set, often triggered after an operating system software update. The device automatically loads the Lenze default settings.
PR3
A checksum error was detected in parameter set 3 during loading or transfer via the keypad. This indicates a fault in the parameter data or incompatibility with the loaded software version. The Lenze default settings are loaded automatically.
PR4
A checksum error was detected in parameter set 4 during loading or transfer via the keypad. This indicates a fault in the parameter data or incompatibility with the loaded software version. The Lenze default settings are loaded automatically.
PI
A fault occurred during parameter initialization, likely during parameter set transfer between two devices, or because the parameter set does not match the controller (e.g., from a higher-power controller to a lower-power one).
PR6
The device has reached the maximum allowed number of user codes. This prevents the creation or storage of additional user-defined settings.
Sd2
A resolver error has occurred at terminal X7, typically indicating an interrupted resolver cable. This prevents accurate position feedback.
Sd3
An encoder error has occurred at terminal X9, typically due to an interrupted encoder cable or pin X9/8 not being connected. This can lead to incorrect or no position feedback.
Sd5
An encoder error has occurred at X6/1 and X6/2 (when C0034 = 1), indicated by a current signal less than 2mA at these terminals. This suggests an open circuit or a faulty current signal encoder.
Sd6
The encoder for detecting motor temperature at X7 or X8 is indicating undefined values. This suggests a problem with the temperature sensor, its cable, or connection.
Sd7
An initialization error occurred at the absolute value encoder at X8, or the encoder electronics are defective. This can result from a loose cable, an open circuit, an incorrect encoder type, or failure during rotor position adjustment.
SinCos encoder at X8 sends inconsistent data.
The SinCos encoder at X8 is sending inconsistent data, indicating damaged internal tracks or high interference on the encoder cable. It could also mean the encoder is not transmitting data due to an open circuit, an incorrect encoder type, or a defective sensor.
PL
The rotor position adjustment was canceled, possibly due to an Sd7 or Sd8 error occurring during the adjustment with an absolute value encoder. This error is saved with mains failure protection.
EEr
External monitoring has been triggered via the DCTRL input. A digital signal assigned to the TRIP-SET function has been activated.
OU
An overvoltage condition exists in the DC bus, where the DC bus voltage is higher than the value set in parameter C0173. This is typically caused by excessive braking energy being fed back to the bus.
LU
An undervoltage condition exists in the DC bus, where the DC bus voltage is lower than the value specified in parameter C0173. This typically indicates insufficient input power to the drive.
H05
An internal fault related to the device's memory has occurred. This typically indicates a hardware issue that requires specialized attention.
H07
An internal fault related to the power stage has occurred. During the initialisation of the controller, an incorrect power stage was detected, indicating a serious internal hardware issue.
H10
The sensor for detecting the heatsink temperature is indicating undefined values. This suggests a fault with the sensor or its connection, leading to unreliable temperature monitoring.
H11
The temperature sensor inside the controller is indicating undefined values. This suggests a fault with the sensor or its connection, leading to unreliable internal temperature monitoring.
Error "negative limit switch".
The negative limit switch has been reached, preventing further movement of the drive in the negative direction. This is a safety mechanism to prevent overtravel.
Error "positive limit switch".
The positive limit switch has been reached, preventing further movement of the drive in the positive direction. This is a safety mechanism to prevent overtravel.
Following error
The angle difference between the set position and the actual position is larger than the following error limit set under parameter C0255. This can also indicate the drive cannot follow the digital frequency due to reaching its Imax limit, suggesting insufficient drive dimensioning.
Error "negative position limit".
The negative position limit (C1224) was not reached, potentially due to incorrect position targets or issues with the 'set function position value'. This can prevent the drive from reaching its intended negative travel extreme.
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.
AddData DlErr Error during FLASH memory access
An error occurred when downloading data into the FLASH memory. This can be caused by a time-out, transmission error, or a mains failure during the data transfer process, resulting in incomplete or corrupt data.
Err Node Guard "Life guarding event"
The controller, configured as a CAN slave, did not receive a 'Node Guarding' telegram from the CAN master within the configured 'Node Life Time'. This indicates a loss of communication supervision on the CAN bus.
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.
