Classification
Remedy
• Check motor and wiring for short circuits.
• Check brake resistor and wiring.
Trouble
• Check motor circuit (delta connection, star connection).
• Check setting of the motor data.
• Check motor cable.
Trouble
• Check the length of the motor cable.
• Use shorter or lower-capacitance motor cable.
Trouble
• Check motor cable for short circuit.
• Check drive sizing.
• Check machine/driven mechanics for excessive load.
Trouble
• Check setting of the motor data.
• Reduce values for slip compensation (P315.01, P315.02) and oscillation damping (P318.01, P318.02).
• Check drive sizing.
Trouble
• Reduce maximum overload current of the inverter (P324.00).
• In case of high mass inertias, reduce maximum overload current of the inverter (P324.00) to 150 %.
Warning
• Check drive sizing.
• Check mains connection wiring.
Trouble
• Check fuses.
Trouble
• Reduce dynamic performance of the load profile.
• Check mains voltage.
• Check settings for the brake energy management.
Warning
• Check mains voltage.
Trouble
• Check fuses.
• Check DC bus voltage (P105.00).
Warning
• Check mains settings.
• Check mains voltage.
Warning
• Check fuses.
• Check mains settings.
• Check mains voltage.
• Provide for a sufficient cooling of the device (display of the heatsink temperature in P117.01).
Trouble
• Clean fan and ventilation slots. If required, replace fan.
• Reduce switching frequency (P305.00).
• Clean fan and ventilation slots. If required, replace fan. The fans can be unlocked via locking hooks and can
Warning
then be removed.
Warning
• Check mains voltage.
Warning
• Check 24 V output and digital outputs for earth fault or overload.
• Check and correct the assignment of the triggers to the functions.
Trouble
• With keypad or network control, the two functions "Inverter enable" (P400.01) and "Run" (P400.02) can also
be set to "Constant TRUE [1]" to start the motor.
