Check whether the motor is overloaded.
Reduce the pulse frequency.
F30005
I2t inverter overload
Check the rated currents of the motor and Power Module.
Reduce current limit p0640.
When operating with U/f characteristic: Reduce p1341.
F30011
Line phase failure
Check the inverter's input fuses.
Check the motor cables.
F30015
Motor cable phase failure
Check the motor cables.
Increase the ramp-up or ramp-down time (p1120).
F30021
Ground fault
•
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).
F30022
Power Module: Monitoring U
CE
Check or replace Power Module.
F30027
Time monitoring for DC link pre-
charging
Check the supply voltage at the input terminals.
Check the line voltage setting (p0210).
F30035
Overtemperature, intake air
•
Check whether the fan is running.
•
Check the fan filter elements.
•
Check whether the ambient temperature is in the permissible range.
F30036
Overtemperature, inside area
F30037
Rectifier overtemperature
See F30035 and, in addition:
•
Check the motor load.
•
Check the line phases
A30049
Internal fan defective
Check the internal fan and if required replace.
F30052
Incorrect Power Module data
Replace Power Module or upgrade CU firmware.
F30053
Error in FPGA data
Replace the Power Module.
F30059
Internal fan defective
Check the internal fan and if required replace.
F30074
Communications error between
Control Unit and Power Module
There is a communications fault between the Control Unit and the Power
Module. Possible causes:
•
The Control Unit may have been removed or inserted incorrectly.
•
The external 24 V Control Unit power supply has dipped to ≤95% of
the rated voltage for ≤3
ms
A30502
DC link overvoltage
•
Check the unit supply voltage (p0210).
•
Check the dimensioning of the line reactor.
F30600
STOP A initiated
Select the STO safety function and then deselect again.
F30662
CU hardware fault
Switch CU off and on again, upgrade firmware or contact technical sup-
port.
F30664
CU power up aborted
Switch CU off and on again, upgrade firmware or contact technical sup-
port.
F30850
Software fault in the Power Module Replace Power Module or contact technical support.
