Operating Instructions, 09/2015, A5E36037884
Cause
An error has occurred during the position
actual vaule preprocessing.
In the PTI mode or a compound mode with
PTI, the P-TRG or CLR function is activat-
ed.
The parameter configuration of PTI coun-
ter is incorrect.
Alarm threshold for I t overload of the
2
power unit exceeded.
The angular commutation offset was re-
defined and has still not been saved.
In order to permanently accept the new
value, it must be saved in a non-volatile
fashion.
The automatic determination of the angular
commutation offset (encoder adjustment)
is activated.
The automatic determination is carried out
at the next power-on command.
The motor data ident. routine is activated.
The motor data identification routine is
carried out at the next power-on command.
The DC link voltage is too low.
11.2 List of faults and alarms
Remedy
Check the encoder for the position actual
value preprocessing.
Refer to F52931.
In the PTI mode, deactivate the P-TRG or
CLR function; in the compound mode with
PTI, do not switch to other modes.
Default the drive and re-configure the param-
eters.
Reduce the continuous load.
•
Adapt the load duty cycle.
•
Check the assignment of the rated cur-
•
rents of the motor and motor module.
This alarm automatically disappears after the
data has been saved.
The alarm automatically disappears after
determination.
The alarm automatically disappears after the
motor data identification routine has been
successfully completed.
If a POWER ON or a warm restart is per-
formed with motor data identification selected,
the motor data identification request will be
lost. If motor data identification is required, it
will need to be selected again manually fol-
lowing ramp-up.
Switch on the load supply.
•
Check the line supply if necessary.
