Solution
1. Increase the ramp-down time (p1121).
2. Set the rounding times (p1130, p1136).
3. Activate the DC link voltage controller (p1240,
p1280).
4. Check the line voltage (p0210).
5. Check the line phases.
1. Check the line voltage (p0210).
2. Check the line phases.
1. Check whether the drive fan is running.
2. Check the ambient temperature.
3. Check whether the motor is overloaded.
4. Reduce the pulse frequency.
1. Check the rated currents of the motor and Power
Module.
2. Reduce the current limit p0640.
3. When operating with V/f characteristic: Reduce
p1341.
1. Check the drives's input fuses.
2. Check the motor cables.
1. Check the motor cables.
2. Increase the ramp-up or ramp-down time (p1120).
1. Check the power cable connections.
2. Check the motor.
3. Check the current transducer.
4. Check the cables and contacts of the brake
connection (a wire might be broken).
1. Check the Power Module.
2. Replace the Power Module, if necessary.
1. Check the supply voltage at the input terminals.
2. Check the line voltage setting (p0210).
Check whether the fan is running.
2. Check the fan elements.
3. Check the ambient temperature.
1. Check whether the fan is running.
2. Check the fan elements.
3. Check the ambient temperature.
4. Check the motor load.
5. Check the line phases.
1. Replace the Power Module.
2. Update the CU firmware.
1. Switch the CU off and on again.
2. Update the firmware.
3. Contact Technical Support.
