3.1 Faults and Alarms – Overview
Fault messages
In the event of a failure, the inverter switches off.
Fault messages are stored in parameter r0947 under their code number (e.g.
F0003 = 3). The associated error value is found in parameter r0949. The value 0
is entered if a fault has no error value. It is furthermore possible to read out the
point in time that a fault occurred (r0948) and the number of fault messages
(P0952) stored in Parameter r0947.
Alarm messages
Alarm messages are stored in parameter r2110 under their code number (e.g.
A0503 = 503) and can be read out from there.

To reset the fault, one of the methods listed below can be used:
1. Cycle the power to the drive
2. Press the - Button on the OP
