4 Faults and alarms
4.2 List of faults and alarms
Remedy:
- check the current limits (p0640).
- vector control: Check the current controller (p1715, p1717).
- U/f control: Check the current limiting controller (p1340 ... p1346).
- increase the up ramp (p1120) or reduce the load.
- check the motor and motor cables for short-circuit and ground fault.
- check the motor for the star-delta configuration and rating plate parameterization.
- check the power unit and motor combination.
- Choose "flying restart" function (p1200) if switched to rotating motor.
F07802
Drive: Infeed or power unit not ready
Message class:
Infeed faulted (13)
Reaction:
OFF2 (NONE)
Acknowledge:
IMMEDIATELY
Cause:
After an internal switch-on command, the infeed or drive does not signal ready.
- monitoring time is too short.
- DC link voltage is not present.
- associated infeed or drive of the signaling component is defective.
- supply voltage incorrectly set.
Remedy:
- increase the monitoring time (p0857).
- ensure that there is a DC link voltage. Check the DC link busbar. Enable the infeed.
- replace the associated infeed or drive of the signaling component.
- check the line supply voltage setting (p0210).

A07805 (N)
Drive: Power unit overload I2t
Message class:
Power electronics faulted (5)
Reaction:
NONE
Acknowledge:
NONE
Cause:
Alarm threshold for I2t overload (p0294) of the power unit exceeded.
The response parameterized in p0290 becomes active.
See also: p0290 (Power unit overload response)
Remedy:
- reduce the continuous load.
- adapt the load duty cycle.
- check the assignment of the motor and power unit rated currents.
F07806
Drive: Regenerative power limit exceeded (F3E)
Message class:
Power electronics faulted (5)
Reaction:
OFF2 (IASC/DCBRK)
Acknowledge:
IMMEDIATELY
Cause:
For blocksize power units, types PM250 and PM260, the regenerative rated power r0206[2] was exceeded for more
than 10 s.
See also: r0206 (Rated power unit power), p1531 (Power limit regenerative)
Remedy:
- increase the down ramp.
- reduce the driving load.
- use a power unit with a higher regenerative feedback capability.
- for vector control, the regenerative power limit in p1531 can be reduced so that the fault is no longer triggered.
