Cause: The braking chopper was inhibited because the unloaded DC link voltage continuously reaches or exceeds the chopper
activation thr
eshold. This prevents the braking chopper from being permanently active and possibly damaged.
Possible causes:
The value of parameter p0210 does not match the line voltage.
Fault value (r0949, interpret decimal): DC link voltage [V]
Remedy: Replace the converter.
F30265 Power unit: Line voltage failure detected
Message class: Power electronics faulted (5)
Message value: -
Component: Power Unit
Response: OFF3
Acknowledgment: IMMEDIATELY
Cause: Line voltage failure was detected
Remedy: - Switch on the line voltage.
- T
o increase t
he degree of ruggedness, the delay time in p3234 can be increased.
- If necessary, line voltage failure detection can be deactivated using p2149.16.

A30266 Power unit: Required modulator setting cannot be implemented
Message class: Hardware/software error (1)
Message value: %1
Component: Power Unit
Response: NONE
Acknowledgment: NONE
Cause: The required modulator setting was not able to be implemented. This can involve some undesirable eects;
for
example,
unexpectedly high switching losses can occur or the current controller bandwidth can be reduced.
Alarm value (r2124, interpret hexadecimal):
Only for internal Siemens troubleshooting.
Remedy: - Carry out a POWER ON (switch-o/switch-on).
A30267 Power unit: Active power overload
Message class: Power electronics faulted (5)
Message value: -
Component: Power Unit
Response: NONE
Acknowledgment: NONE
Cause: The alarm threshold for the active power overload of the power unit has been exceeded. Depending on the selected
o
ver
load response, the output current and therefore the output frequency can be reduced. If the current reduction is not
sucient to thermally relieve the power unit, then when the fault threshold for overload is reached the drive switches o
the power unit and outputs fault F30268.

Remedy: - Reduce the continuous load.
- Adapt t
he load duty cycle.
