SEW Eurodrive MOVIDRIVE compact System

No fault is currently active within the drive system. The MOVIDRIVE® unit is operating normally without any detected issues. This status indicates a healthy system state, requiring no immediate intervention.

An excessive current flow has been detected in the drive's output stage, potentially due to a short circuit, an oversized motor, or a defective output stage component. This fault triggers an immediate shutdown to prevent damage to the inverter or motor.

An electrical current path to ground has been detected, which could be in the incoming power cable, within the inverter itself, or in the connected motor. This fault causes an immediate shutdown of the drive to mitigate risks of electrical shock and equipment damage.

The braking chopper circuit has encountered an issue, such as excessive regenerative power, an open or shorted braking resistor circuit, incorrect resistor resistance, or a defective chopper component. This fault leads to an immediate switch-off, impairing the drive's braking capabilities.

The DC link voltage has exceeded its permissible maximum limit, often caused by excessive regenerative power generated during braking, or potentially a ground fault. This triggers an immediate switch-off to protect the inverter's sensitive electronic components from damage.

The speed or current controller is operating at its setting limit, indicating either a mechanical overload, a phase failure in the power supply or motor, or an incorrectly connected/configured encoder. This fault suggests the motor is not behaving as commanded, leading to an immediate shutdown.

The inverter has not been properly commissioned or taken into operation for the selected operating mode. This prevents the drive from starting and requires the user to complete the initial setup process.

An incorrect or unsupported command was detected during the execution of the IPOS plus® program, or the conditions for command execution were not met. This fault indicates a programming error within the IPOS logic, resulting in an emergency stop.

The inverter has experienced a thermal overload, indicating either that the connected load is too high for the drive or that the cooling system is inadequate. This fault triggers an emergency stop to prevent overheating and potential damage to the inverter's internal components.

This fault occurs when 14-bit resolver evaluation is active, and the actual motor speed has exceeded the maximum allowed limit of 3600 1/min (RPM). Exceeding this speed can lead to inaccurate feedback and triggers an emergency stop.

The control signal source for the inverter's operation has not been defined or has been defined incorrectly. This prevents the inverter from receiving valid control commands, causing an immediate switch-off.

An issue with the encoder has been detected, such as incorrect cabling, a short circuit or broken wire in the encoder line, or a defective encoder unit itself. This compromises speed and position feedback, leading to an immediate switch-off of the drive.

The internal DC 24 V supply voltage required for the inverter's control electronics is absent. This critical power supply issue leads to an immediate disconnection of the unit, as essential control functions cannot be powered.

A general malfunction of the inverter electronics has occurred, potentially due to electromagnetic compatibility (EMC) influences or an internal hardware issue. This leads to an immediate disconnection to prevent further damage or erratic behavior.

An error occurred during access to the EEPROM (Electrically Erasable Programmable Read-Only Memory), where the drive parameters are stored. This can lead to rapid stopping and potentially corrupted or lost drive settings.

An external error signal has been received via a programmable input terminal. The specific cause of this error is determined by the external device connected to this input, triggering an emergency stop in the drive system.

An open circuit has been detected in the limit switch wiring, or both limit switches are missing, or they are incorrectly swapped relative to the motor's direction of rotation. This fault prevents proper travel control and triggers an emergency stop.

Communication between the fieldbus master and the MOVIDRIVE® slave has been interrupted or failed to occur within the projected response monitoring time. This fault leads to a rapid stop, indicating a loss of control from the fieldbus system.

A limit switch has been reached while the drive is operating in IPOS mode, indicating that the motor has reached the end of its programmed travel range or an unexpected position. This fault triggers an emergency stop to prevent mechanical damage.

The drive has either been overloaded or the emergency stop ramp is too short, causing the stop condition not to be met within an expected timeframe. This results in an immediate disconnection to prevent further issues or damage.

The motor's thermal sensor (TF sensor) has tripped, indicating the motor has become too hot, or the sensor itself is not connected, connected incorrectly, or its connection to the MOVIDRIVE® is interrupted. This fault typically triggers a 'No Response' action, which can be configured as a warning or a soft stop.

The IPOS plus® user program has violated programming principles, leading to an internal system stack overflow. This indicates a complex programming error within the IPOS logic that triggers an emergency stop.

The setpoint source for the drive's operation has not been defined or has been defined incorrectly. This prevents the inverter from receiving valid command values for speed or position, leading to an immediate disconnection.

The operating mode for the inverter has not been defined or has been defined incorrectly. This prevents the drive from functioning properly, as it cannot determine how to operate, resulting in an immediate disconnection.

An error occurred during the execution of the system software, indicating a critical internal fault within the inverter's control system. This type of fault typically leads to an immediate disconnection to prevent further system instability.

A general system error related to the inverter's core software has occurred, indicating a critical internal fault. This issue can prevent proper drive operation and leads to an immediate disconnection.

An issue occurred during the reference travel (homing) procedure, such as a missing or non-switching reference cam, incorrectly connected limit switches, or a change in reference travel type during the process. This results in an immediate disconnection, preventing proper homing and position control.

An error has occurred in communication between the system software and option software, or a watchdog within the IPOS program has triggered. This can also result from loading an application module without the correct application version or setting an incorrect technology function, leading to an immediate disconnection.

The actual position or speed deviates significantly from the commanded value, potentially due to incorrect encoder connection, short acceleration ramps, a small P-component in the positioning controller, incorrect speed controller parameters, or an insufficient lag fault tolerance. This causes an immediate disconnection to prevent further uncontrolled movement.

The communication connection between the inverter and a connected PC or master device via RS485 has been interrupted or timed out. This fault results in a rapid stop, indicating a loss of diagnostic or control communication over the serial interface.

The inverter's utilization, based on its I²t (current squared time) thermal model, has exceeded 125%, indicating a sustained overload condition. This fault leads to an immediate disconnection to protect the inverter's power section from thermal damage due to prolonged high currents.

Parameters for the EEPROM in the power section are either not set or incorrectly set, preventing proper initialization of the drive system. This critical issue causes an immediate disconnection as the drive cannot start with invalid base settings.

An error occurred during communication via the internal system bus within the MOVIDRIVE® unit. This indicates a problem with the inverter's internal communication architecture, resulting in a rapid stop of the drive.

A communication error has occurred within the inverter system, specifically between the fieldbus interface and the inverter system itself. This may prevent the requested parameter service from being executed and often indicates a temporary internal data exchange issue. The error class is 'Access' and error code is 'Hardware fault'.

During a write service via the parameter channel, an incorrect data length was specified (other than 4 data bytes). This error is generated by the fieldbus card's communication software and indicates a mismatch between the expected data size and the actual data provided for a parameter. This prevents correct parameter configuration.

In IPOS operating mode, an attempt was made by an external controller to set an invalid automatic mode via the control word, or parameter P916 is set incorrectly. This leads to a 'no response' behavior, preventing unintended or unsafe operation.

This fault occurs in IPOS operating mode when the programmed target position attempts to exceed the travel range defined by the software limit switches. The inverter receives a target position command that is physically or logically out of bounds for the configured travel limits. This prevents the drive from moving to the commanded position.

The parameter index specified in the communication request is invalid or not recognized by the inverter. This implies an attempt to access a non-existent parameter or a typo in the parameter address. This error is returned under error class 8 (other error) and prevents the requested parameter operation.

The specific function or parameter being requested is not implemented in the current inverter's firmware or hardware configuration. This can occur if the inverter unit does not support a particular feature, or if a required optional module is missing. The requested operation cannot be performed.

An attempt was made to write data to a parameter that is configured for read-only access. This parameter's value cannot be altered via communication, either by design or due to its current operational state. The write operation is rejected.

The parameter being accessed is currently locked, preventing any modification. This lock can be activated by the system's operational state, security settings, or a specific user program. Any attempt to change the parameter will be rejected until the lock is released.

This indicates that the inverter is currently operating with its default factory settings. While not an error in itself, it confirms that custom parameterization may not be active or an attempt to write a specific parameter has been rejected because factory settings are overriding it. The system is in a default state.

The value provided for the parameter exceeds its defined maximum permissible limit. This means the requested setting is outside the operational or hardware capabilities for that specific parameter. The parameter value is rejected and not applied.

The value provided for the parameter is below its defined minimum permissible limit. This means the requested setting is less than the smallest allowed value for that specific parameter, often due to physical limitations or control stability requirements. The parameter value is rejected.

The function or parameter being accessed requires a specific option card to be installed in the inverter, which is currently absent. This hardware dependency prevents the requested operation from being executed. The feature associated with the missing option card cannot be utilized.

An internal error has occurred within the inverter's system software. This could be caused by temporary disruptions, corrupted firmware, or a fault in the hardware components supporting the software. This critical error affects the inverter's operational integrity.

The parameter being accessed is restricted to modification or reading solely through the RS-485 process interface (X13). Attempts to access this parameter from any other communication interface will be rejected. This is often a design choice for critical process parameters.

The parameter being accessed is restricted to modification or reading solely through the RS-485 diagnostics interface. Attempts to access this parameter from any other communication interface will be rejected. This limitation is typically for parameters related to diagnostics or maintenance.

The parameter is currently protected by an access mechanism, such as a password, a specific user level, or an operational state. This protection prevents unauthorized or accidental modification of the parameter's value. Any attempt to write to it without proper authorization will be rejected.

The requested parameter change or action cannot be performed while the inverter's controller is active (enabled). For safety or operational integrity, this parameter requires the controller to be inhibited (disabled) before modification. Attempts to change it during active control will result in this error.

The value provided for the parameter is invalid, not necessarily because it's outside the numerical range, but due to an incorrect format, data type, or unsupported option. This means the input does not conform to the parameter's expected structure or choices. The inverter rejects the invalid value.

Occurs specifically in 'VFC hoist' operating mode. The motor was unable to draw the correct amount of current during the pre-magnetizing phase of startup. This can be caused by an undersized motor for the inverter's power rating or insufficient cross-section of the motor cables, leading to excessive voltage drop. The inverter immediately disconnects to prevent damage.

This fault occurs in 'VFC hoist' operating mode when two or all output phases to the motor are interrupted. It can also indicate a significant mismatch where the rated motor power is too small relative to the inverter's power. The inverter detects an open circuit condition on its output, leading to immediate disconnection.

This fault indicates that the motor utilization is too high, meaning the motor is operating under excessive load. This condition can lead to motor overheating and premature failure if not addressed. The inverter initiates an emergency stop to protect the motor.

An error occurred during the process of copying parameters within the inverter, typically when transferring settings between the inverter and a PC. This can indicate a communication issue or corrupted data during the transfer. The inverter immediately disconnects to maintain system integrity.

This fault occurs when an attempt is made to load a parameter set for an application version unit (with technology functions activated) into a standard version unit. Standard units do not support advanced technology functions, causing a conflict during parameter loading. The inverter immediately disconnects.

Observed exclusively in VFC n-CTRL operating mode. This fault indicates that the inverter was enabled while the actual motor speed exceeded 5000 1/min. The inverter's flying start function has a speed limit for engagement, and exceeding this limit prevents proper control. The inverter immediately disconnects to prevent unstable operation.

This fault signals a disruption in the inverter's internal electronics, specifically an EEPROM checksum error. This can be caused by external electromagnetic compatibility (EMC) interference or an internal defect within the inverter's hardware, potentially leading to corrupted stored parameters. The inverter immediately disconnects to prevent operation with compromised data.

This fault occurs in IPOS operating mode when attempting to change ramp times or traveling velocities while the inverter is enabled, especially with sinusoidal or square positioning ramps. Modifying these parameters dynamically during active operation can lead to an uncalculatable state for the ramp profile. The inverter immediately disconnects to prevent unsafe movement.

The inverter has detected that the output current exceeded 185% of the rated output current for more than 60 milliseconds. This indicates a significant overload on the motor or a short circuit in the output wiring. This will cause an immediate switch-off of the inverter to prevent damage to the motor or the drive.
