SEW Eurodrive MOVIMOT MM..C
21 fault codes documented
Overcurrent of output stage
This fault indicates a short circuit at the inverter output, which can lead to excessive current draw and potential damage to the output stage of the MOVIMOT® unit.
Mains phase fault
This fault signifies a phase loss or imbalance in the incoming power cables. It can only be reliably detected when the drive is under load.
DC link voltage too high
This fault occurs when the DC link voltage exceeds its safe operating limits. This condition can be caused by regeneration from the motor, short ramp times, or issues with the braking resistor configuration.
Speed Monitoring Tripped
The MOVIMOT® signals a fault (red LED flashing slowly) if the drive operates at its current limit for more than 1 second while speed monitoring is active. The current limit must be continuously attained for the duration of a pre-set delay time before this monitoring function responds. This indicates a sustained overload condition or a blockage that prevents the motor from reaching its commanded speed.
Thermal overload of output stage or internal unit fault
This fault indicates excessive temperature within the inverter's output stage or a general internal malfunction of the unit. Common causes include inadequate cooling, high ambient temperatures, or operation under excessive load.
CPU fault
This fault code, or codes within the range 17-24, or code 37, indicates an internal CPU malfunction within the MOVIMOT® unit, suggesting an internal processing error.

CPU fault
This fault code, or codes within the range 17-24, or code 37, indicates an internal CPU malfunction within the MOVIMOT® unit, suggesting an internal processing error.
EEPROM error
This fault indicates an error with the internal EEPROM, which stores critical configuration data for the MOVIMOT® unit. This could signify data corruption or a hardware issue with the EEPROM.
CPU fault
This fault code, or codes within the range 17-24, or code 37, indicates an internal CPU malfunction within the MOVIMOT® unit, suggesting an internal processing error.
Adjustable Current Limitation Exceeded
This fault occurs when the MOVIMOT® drive operates at its adjustable current limit for more than 500 ms, specifically when the operating frequency is above 15 Hz. The unit indicates this status via rapid red flashing. It signifies that the motor or connected load is drawing current continuously beyond the configured maximum set by switch f2.
Overtemperature Motor (via TH)
Fault 84 'Overtemperature Motor' is tripped if the TH (thermal sensor) connected to the direction of rotation terminals (L and R) opens due to excessive motor temperature. This fault occurs in conjunction with MOVIMOT® inverter mounting close to the motor (P2.A option or in a field distributor) and when both direction of rotation terminals are opened by the TH. This indicates the motor has reached a critical temperature, triggering its thermal protection.
Thermal overload of brake coil or brake coil defective
This fault indicates that the brake coil has overheated or is defective. It may be caused by frequent braking operations, excessively short ramp times, a mismatch between the drive and the MOVIMOT® frequency inverter, or incorrect internal resistance of the brake coil.
Assignment of motor – inverter incorrect
This fault indicates a mismatch or incorrect combination between the motor and the inverter, such as pairing an MM03 inverter with a DT71D4 motor, which is not a supported configuration.
Communication error between field-bus gateway and MOVIMOT®
This fault is generated by the bus module and indicates an issue with the RS-485 communication link between the fieldbus gateway and the MOVIMOT® unit, typically stemming from electrical connection problems.
EEPROM error
This fault indicates an error with the internal EEPROM, which stores critical configuration data for the MOVIMOT® unit. This could signify data corruption or a hardware issue with the EEPROM.
