4.2 List of faults and alarms
F07802 Drive: Infeed or power unit not ready
Message value: -
Message class: Infeed faulted (13)
Drive object: VECTOR_G
Component: None Propagation: GLOBAL
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 value: -
Message class: Power electronics faulted (5)
Drive object: VECTOR_G
Component: Power Module Propagation: GLOBAL
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 rated currents of the motor and Motor Module.
Reaction upon N: NONE
Acknowl. upon N: NONE
