SEW Eurodrive MOVIMOT MM..D With AC Motor DRS
16 fault codes documented
Overcurrent in output stage
An overcurrent condition has been detected in the inverter's output stage, often due to a short circuit. This can occur either within the inverter output itself, the connecting cable to the motor, or the motor windings.
Phase failure
A phase failure has been detected in the supply system to the drive. This error can only be detected when the drive is operating under load, indicating a loss of one or more input phases.
DC link voltage too high
The DC link voltage has exceeded its permitted threshold. This condition often arises from regenerative braking if the ramp time is too short, issues with the braking resistor/coil, or an invalid supply input voltage.
Speed monitoring
The speed monitoring function has triggered, indicating that the load on the drive is too high for the current operating conditions. This error is typically active when DIP switch S2/4 is set to 'ON' or when additional function 13 is active.
Thermal overload of output stage or internal unit error
The output stage of the inverter or an internal component has exceeded its thermal limits. This can be caused by insufficient cooling, high ambient temperatures, or an excessive load on the drive.
CPU error
A CPU error (covering codes 17 to 24 and 37) has occurred within the inverter unit, indicating an internal processing issue. This typically requires a system reset to clear.
EEPROM error
An error has been detected in the EEPROM, which stores essential configuration and operating data. This could indicate data corruption or a hardware fault, requiring a reset.
Communication timeout (RS-485)
A communication timeout occurred during cyclical communication via the RS-485 interface. Upon this error, the drive will decelerate and stop along its set ramp. Communication must be re-established to re-enable the drive.
Adjustable current limitation exceeded
The drive has operated at its set current limit for longer than 500 ms when additional function 2 (adjustable current limitation) is active and the monitoring function is in effect (above 15 Hz). This indicates the motor is drawing too much current.
Start condition error
The motor could not be supplied with the correct amount of current during its pre-magnetizing time, preventing a proper start-up sequence. This often points to a mismatch between inverter and motor ratings or issues with cabling.
Output phases interrupted
Two or all output phases to the motor are interrupted, or there is a significant mismatch between the motor and inverter power ratings, preventing the motor from receiving power correctly.
Thermal overload of motor
The motor has exceeded its safe operating temperature, triggering thermal monitoring. This can be due to environmental factors, excessive load, incorrect drive configuration, or the activation of an external winding thermostat. This error is triggered when the standard MOVIMOT® motor protection via DIP switch S1/5 set to 'ON' is deactivated, and an external TH connected to terminals X6:1,2,3 has tripped.
Thermal overload of brake coil or brake coil defective/incorrectly connected
The brake coil has experienced a thermal overload, is defective, or is connected improperly. This can lead to braking issues, potential drive damage, and requires inspection of the brake system.
Assignment of motor to inverter incorrect
The parameters defining the motor's assignment within the inverter configuration are incorrect. This can lead to operational issues as the inverter is not correctly controlling the connected motor.
EEPROM checksum error
An inconsistency in the EEPROM's data has been detected, indicating a potential data corruption or a defective EEPROM component. This specifically refers to a checksum mismatch, highlighting data integrity issues.
Copy error (Parameter transmission error)
An error occurred during the copying process of parameters (also referred to as parameter transmission error), potentially due to interruption of the connection or power supply during data transfer from a keypad or PC.
