Message value: %1
Component: Power Unit
Response: OFF2
Acknowledgment: IMMEDIATELY
Cause: The temperature of the power unit heat sink has exceeded the permissible limit value.
- Insu󹪟cient cooling, fan failur
e.
- Over
load.
- Ambient temperature too high.
- Pulse frequency too high.
Fault value (r0949, interpret decimal):
Temperature [0.01 °C].
Remedy: - Check whether the fan is running.
- Check the fan elements.
- Chec
k 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 the alarm threshold for alarm A30250 has been fallen below.
F30005 Power unit: Overload I2t (AC)
Message class: Power electronics faulted (5)
Message value: %1
Component: Power Unit
Response: OFF2
Acknowledgment: IMMEDIATELY
Cause: The fault threshold for the I2t overload on the AC side of the power unit has been exceeded. The permissible load duty cycle
or t
he continuous load was no
t maintained.
Fault value (r0949, interpret decimal):
I2t (AC) [100 % = 16384]
See also: r0036 (Power unit overload)
Remedy: - Reduce the continuous load.
- Adapt t
he load duty cycle.
- Check the rated currents of the motor and power unit.

F30011 Power unit: Line phase failure in main circuit
Message class: Network fault (2)
Message value: %1
Component: Power Unit
Response: OFF2
Acknowledgment: IMMEDIATELY
Cause: At the power unit, the DC link voltage ripple has exceeded the permissible limit value.
P
ossible causes:
- A line phase has failed.
- The 3 line phases ar
e inadmissibly asymmetrical.
- The capacitance of the DC link capacitor forms a resonance frequency with the line inductance and the reactor integrated
in the power unit.
- The fuse of a phase of a main circuit has ruptured.
- A motor phase has failed.
- For power units operated on a single phase, the permissible active power was exceeded.
