Remedy:
- check the line phase connection.
- check the motor feeder cable connections.
If there is no phase failure of the line or motor, then line asymmetry is involved.
- reduce the power in order to avoid fault F30011.
F30059
Power unit: Internal fan faulty
Reaction:
OFF2
Acknowledge:
IMMEDIATELY
Cause:
The internal power unit fan has failed and is possibly defective.
Remedy:
Check the internal fan and replace if necessary.
A30065 (F, N) Voltage measured values not plausible
Reaction:
NONE
Acknowledge:
NONE
Cause:
The voltage measurement is not supplying any plausible values
Alarm value (r2124, interpret bitwise binary):
Bit 1: Phase U.
Bit 2: Phase V.
Bit 3: Phase W.
Remedy:
- Deactivate voltage measurement (p0247.0 = 0).
- Deactivate flying restart with voltage measurement (p0247.5 = 0) and deactivate fast flying restart (p1780.11 = 0).
F30068
Power unit: undertemperature inverter heat sink
Reaction:
OFF2
Acknowledge:
IMMEDIATELY
Cause:
The actual inverter heat sink temperature is below the permissible minimum value.
Possible causes:
- the power unit is being operated at an ambient temperature that lies below the permissible range.
- the temperature sensor evaluation is defective.
Fault value (r0949, interpret decimal): inverter heat sink temperature [0.1 °C].
Remedy:
- ensure that higher ambient temperatures prevail.
- replace the power unit.
F30071
No new actual values received from the Power Module
Reaction:
OFF2
Acknowledge:
IMMEDIATELY
Cause:
More than one actual value telegram from the power unit module has failed.
Remedy:
Check the interface (adjustment and locking) to the power unit module.
F30072
Setpoints can no longer be transferred to the Power Module
Reaction:
OFF2
Acknowledge:
IMMEDIATELY
Cause:
More than one setpoint telegram was not able to be transferred to the power unit module.
Remedy:
Check the interface (adjustment and locking) to the power unit module.
F30074 (A)
Communication error between the Control Unit and Power Module
Reaction:
NONE
Acknowledge:
IMMEDIATELY
