Remedy: Replace the power unit or update of the FPGA data by updating the 󹪝rmware.
Not
e:
If this fault occurs after a 󹪝rmware update, then update the 󹪝rmware again.
F30055 Power unit: Braking chopper overcurrent
Message class: Braking Module faulted (14)
Message value: -
Component: None
Response: OFF2
Acknowledgment: IMMEDIATELY
Cause: An overcurrent condition has occurred in the braking chopper.
Remedy: - Check whether the braking resistor has a short-circuit.
- F
or an external braking r
esistor, check whether the resistor may have been dimensioned too small.
Note:
The braking chopper is only enabled again at pulse enable after the fault has been acknowledged.
A30057 Power unit: Line asymmetry
Message class: Network fault (2)
Message value: %1
Component: Power Unit
Response: NONE
Acknowledgment: NONE
Cause: Frequencies have been detected on the DC link voltage that would suggest line asymmetry or failure of a line phase.
It is also pos
sible that a motor phase has failed.
If
these frequencies occur with the same or even higher amplitudes, then after a device-speci󹪝c time elapses, fault F30011
is output
Alarm value, only for internal Siemens troubleshooting.
Remedy: - Check the line phase connection.
- Check the motor f
eeder 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.
F30058 Power unit: heat sink fan defective
Message class: External measured value / signal state outside the permissible range (16)
Message value: Fault cause: %1 bin
Component: Power Unit
Response: OFF2
Acknowledgment: IMMEDIATELY
Cause: The feedback signal of the heat sink fan signals a fault, or there is a communication error with the fan.
- F
an defective.
- Fan bloc
ked.
- Feedback signal error.
Fault value (r0949, interpret binary):
Value in bits 0 to 15:
0: Feedback signal of the fan signals a fault
1: Internal communication error to the fan
Bits 16 to 31 are only for internal Siemens diagnostics.
