Error message
See chapter 13.1.1 “Error messages”.
Shut-down
Brake resistor connec-
tion
Check.
Brake resistance
Check value. Reduce value if necessary.
High generator power
Reduce deceleration value.
High DC-link voltage
Check brake resistance.
Check brake resistor connection.
Reduce deceleration value.
Check DC-link voltage limitation (P680).
DC-link voltage higher than brake chopper trigger
threshold (P506). Check value. Increase value if nec-
essary.
DC-link voltage higher than motor chopper trigger
threshold (P507). Check value. Increase value if nec-
essary.
Main phase failure
Check mains connection.
Overcurrent
Check motor data.
Check motor connection.
Short-circuit or overload
The parameterizable motor circuit breaker (P571) has
been triggered. Short-circuit at motor connection or
overload.
Earth fault
Check load for earth fault.
Overtemperature
Overload. Reduce load and ensure sufficient cooling.
Comply with permissible ambient conditions.
Reduce output power or switching frequency.
Electromagnetic inter-
ference
Check EMC.
Overfrequency
Switch-off limit (P417) exceeded. Increase value if
necessary.
Maximum frequency increase (P681) of DC-link volt-
age limitation exceeded. Increase value if necessary.
Parameter setting
not possible.
Enable is switched on
and motor is running.
Most parameters cannot be written during operation.
Switch off enable and select "Para" menu on opera-
tor panel.
Access limited.
Select higher control level (P28).
Setup is active.
Wait until setup is finished and the message "ready"
is displayed.
Changes disabled by
password.
Entry must correspond to password (P27).
Motor does not
turn after press-
ing of RUN.
Parameter setting
For P412, select "3 - Control via keypad" or "4 - Con-
trol via keypad or contacts" (factory setting).
Check P418 (Minimum frequency) and P419 (Maxi-
mum frequency).
No enable
Switch on both enable inputs STOA and STOB.
Error in control cables
Check control cable connections.
