zation aids 
for control 
engineers
The following presents a systematic procedure for setting of the control.
Note: In the event of strong load surges resulting in rapid speed
changes, the stator flux orientation of the SFC may be lost,
and current overload shut-offs (error E-OC) may occur. This
error is counteracted by the “current-controlled startup” func-
tion (see section 5.5.11) setting a steep lowering ramp.
 Step Checks Help
1
Check that your wiring is connected properly 
and the phase sequence is correct.
see section 2.1 “Device and terminal 
view”.
2
Enter correct (plausible) motor data and start 
auto-tuning.
see section 5.1 “_15 FC-Initial com-
missioning”.
3 Check the fault voltage compensation.

4
Check the limit values for the apparent 
current.
