SEW Eurodrive Drives

An excessive current has been detected in the output stage of the MOVIMOT inverter. This typically indicates a short circuit, ground fault, or severe mechanical motor overload, causing the output current to exceed safe limits.

An error has occurred in the internal brake chopper circuit of the MOVIMOT drive. This circuit is responsible for dissipating regenerative energy generated by the motor during deceleration.

A phase failure has been detected in the main supply system. This error can only be reliably detected when the drive is operating under load, as the current draw allows for identification of a missing phase.

The DC link voltage within the inverter has exceeded its permissible maximum threshold. This typically indicates an issue with regenerative energy returning to the drive or an overvoltage condition on the supply voltage.

A speed monitoring error has occurred. This fault is only active when DIP switch S2/4 is set to "ON" or when additional function 13 is active. It indicates a discrepancy in motor speed feedback or an unexpected speed condition.

A startup error has occurred, indicating that certain additional functions are not permitted in the current configuration. Specifically, additional functions 4, 5, or 12, controlled by DIP switches S2/5 through S2/8, are active but are not allowed.

The MFI signals a periphery fault when a microprocessor reset has been carried out, typically due to EMC problems or defective hardware. This code logs the last 10 periphery faults, indicating intermittent or persistent issues.

A fault has occurred in an INTERBUS station (device). The length code of the indicated MFI does not correspond with the entry in the INTERBUS configuration frame, leading to a mismatch in device identification.

The INTERBUS data transfer was cancelled, either because the initialization of the SUPI 3 protocol chip failed or the MFI is defective. This fault code can also be displayed if a reserved DIP switch setting is selected.

The outgoing MFI interface (OUT1) was activated even though no station is connected or was configured in the master. This indicates a mismatch between the physical setup and the INTERBUS master configuration.

The temperature within the inverter's output stage has exceeded its safe operating limit. This indicates potential overheating due to excessive load, high ambient temperatures, or insufficient cooling for the drive electronics.

The MOVIMOT drive was operated at a setpoint speed below 5 Hz for more than 60 seconds. This violates the requirements for Ex-e protection, which demands a minimum operating speed to ensure safe operation in potentially explosive atmospheres.

The 24 VDC supply voltage, which powers the MOVIMOT drive's control electronics, is faulty or missing. This is a critical voltage for the internal logic and communication.

An internal Central Processing Unit (CPU) error has occurred within the MOVIMOT® inverter, indicating a potential hardware or firmware malfunction.

A general CPU error has occurred within the MOVIMOT drive's control unit. This indicates an internal processing fault or an issue with the microcontroller, suggesting a hardware or firmware problem.

An internal Central Processing Unit (CPU) error has occurred within the MOVIMOT® inverter, indicating a potential hardware or firmware malfunction.

An error occurred while accessing the internal EEPROM of the MOVIMOT® inverter, potentially indicating data corruption or a defective memory chip. This can affect stored parameters and operational settings.

An error occurred with the EEPROM (Electrically Erasable Programmable Read-Only Memory) of the MOVIMOT drive. This memory is crucial for storing configuration data, parameters, and operational settings.

An external signal at terminals X6:9 and X6:10 is not present or not in the expected state. This typically relates to an external safety circuit or control input not meeting its required condition.

The configured operating type is not available, or the Drive ID Module (DIM module) is defective. This prevents the MOVIMOT® inverter from operating correctly under the selected mode.

An internal Central Processing Unit (CPU) error has occurred within the MOVIMOT® inverter, indicating a potential hardware or firmware malfunction.

An unspecified internal error has occurred within the MOVIMOT® inverter. This type of error usually requires specialized diagnostic tools and expertise.

An inconsistency or error has been detected in the configured unit or motor data. This suggests a mismatch between the drive's internal settings and the connected motor, or an issue with the drive's own configuration parameters.

A communication timeout occurred during cyclical communication via RS485. This results in the drive decelerating and stopping along its set ramp, indicating a disruption in the continuous data exchange.

The motor current has exceeded the configured current limit for a sustained period of more than 500 ms. This fault specifically occurs only when additional function 2 is active, indicating a persistent overload condition.

The motor could not be supplied with the correct amount of current during the pre-magnetizing time. This can indicate a mismatch between the motor's rated power and the inverter's nominal power, or a connection issue.

Two or all output phases between the MOVIMOT® inverter and the motor are interrupted. This can also occur if the rated motor power is too small compared to the nominal inverter power, affecting current distribution.

The motor has been operating under an overload condition, causing its temperature to rise excessively or its current draw to exceed safe limits for an extended period. This can lead to motor damage if not addressed.

The integrated motor brake has exceeded its safe operating temperature limit. This is often caused by frequent braking cycles, continuous brake slipping, or high ambient temperatures affecting the brake mechanism.

A mismatch has been detected between the assigned motor type and the MOVIMOT inverter. This indicates that the connected motor is incompatible with the inverter's configuration or capabilities.

The communications link between the fieldbus interface (MFP/MFI) and the MOVIMOT® inverter is interrupted or experiences a timeout. This system fault is signaled to the PLC as error code 91 dec via the diagnostics channel or status words, and typically triggers a steady 'SYS-F' LED light on the fieldbus interface.

An EEPROM checksum error indicates that the stored data in the EEPROM is corrupted or the EEPROM itself is defective. This prevents reliable operation as critical configuration data cannot be verified.

An error occurred during the transmission of a parameter set or during a copy process. This typically happens if the DBG keypad or PC is disconnected, or the 24 V supply voltage is interrupted while copying data.
