Remedy
Check the following:
• Motor data, if required, carry out commissioning
• Motor connection method (Υ / Δ)
• U/f operation: Assignment of rated currents of motor and Power Module
• Line quality
• Power cable connections
• Power cables for short-circuit or ground fault
• Power cable length
• Line phases
If this doesn't help:
• U/f operation: Increase the acceleration ramp
• Reduce the load
• Replace the power unit
Increase the ramp-down time (p1121).
Set the rounding times (p1130, p1136).
Activate the DC link voltage controller (p1240, p1280).
Check the line voltage (p0210).
Check the line phases.
Check the line voltage (p0210).
Check whether the converter fan is running.
Check whether the ambient temperature is in the permissible range.
Check whether the motor is overloaded.
Reduce the pulse frequency.
Check the rated currents of the motor and Power Module.
Reduce current limit p0640.
When operating with U/f characteristic: Reduce p1341.
Check the converter's input fuses.
Check the line cables.
Check the motor cables.
Increase the ramp-up or ramp-down time (p1120).
• Check the power cable connections.
• Check the motor.
• Check the current transformer.
• Check the cables and contacts of the brake connection (a wire might
be broken).
Check or replace the Power Module.
CE
Check the supply voltage at the input terminals.
Check the line voltage setting (p0210).
• Check whether the fan is running.
• Check the fan filter elements.
• Check whether the ambient temperature is in the permissible range.
See F30035 and, in addition:
• Check the motor load.
• Check the line phases
Replace Power Module or upgrade CU firmware.
Check the unit supply voltage (p0210).
Switch CU off and on again, upgrade firmware, or contact technical support.
Switch CU off and on again, upgrade firmware, or contact technical support.
Replace Power Module or contact technical support.
Check that the sensor is connected correctly.
