Remedy:
- check the motor data - if required, carry-out commissioning.
- check the motor circuit configuration (star-delta).
- V/f operation: Increase the up ramp.
- V/f operation: Check the assignment of the rated currents of the motor and motor module.
- infeed: Check the line supply quality.
- infeed: Reduce the load when motoring.
- infeed: Correct connection of the line commutating reactor.
- check the power cable connections.
- check the power cables for short-circuit or ground fault.
- check the length of the power cables.
- replace power module.
F30002
Power module: DC link overvoltage
Reaction:
OFF2
Acknowledge:
IMMEDIATELY
Cause:
The power module has detected an overvoltage condition in the DC link.
- motor regenerates too much energy.
- line supply voltage too high.
Fault value (r0949, decimal):
DC link voltage [1 bit = 100 mV].
Remedy:
- increase the ramp-down time.
- activate the DC link voltage controller.
- use a brake resistor or active line module.
- increase the current limit of the infeed or use a larger module (for the active line module).
- check the line supply voltage.

F30003
Power module: DC link undervoltage
Reaction:
OFF2
Acknowledge:
IMMEDIATELY
Cause:
The power module has detected an undervoltage condition in the DC link.
- line supply failure
- line supply voltage below the permissible value.
- line supply infeed failued or faulted.
Remedy:
- check the line supply voltage
- check the line supply infeed and if necessary observe the fault messages of the line supply infeed.
Note:
The ready signal of the infeed r0863 must be connected to the associated inputs p0864 of the drives.

F30004
Power module: Overtemperature heatsink AC inverter
Reaction:
OFF2
Acknowledge:
IMMEDIATELY
Cause:
The temperature of the power module heatsink has exceeded the permissible limit value.
- insufficient cooling, fan failure.
- overload
- ambient temperature too high.
- pulse frequency too high.
Fault value (r0949):
Temperature [1 bit = 0.01 °C].
Remedy:
- check whether the fan is running.
- check the fan elements
- check whether the ambient temperature is in the permissible range.
- check the motor load.
- reduce the pulse frequency if this is higher than the rated pulse frequency.
Notice:
This fault can only be acknowledged after this alarm threshold for alarm A05000 has been fallen below.
