6.1.5 Tips and optimi-
zation aids
for control
engineers
The following section presents a tips and optimization aids to deal with
typical application errors.
Note: Please take note of the general information regarding the
properties of the motor control methods in the introduction to
section 6 “Control modes”
Step Checks Help
1
Check that your wiring is connected pro-
perly and the phase sequence is correct.
see section 2.1 “Device and terminal
view”.
2
In IEC standard motors:
Enter correct (plausible) motor data and
start auto-tuning.
see section 5.1 “_15 FC-Initial commis-
sioning”.
In special, reluctance or synchronous
motors:
Continue with step 3.
3 Check the current injection.
Optimization of current injection in this
section.
4 Check the IxR load compensation.
Optimization of IxR load compensation in
this section.
5 Check the boost voltage.
Optimization of boost voltage in this
section.
6
Check the interaction between current
injection, IxR load compensation and
boost voltage.
Optimization of the interaction in this
section.
7 Check the voltage frequency control.
Optimization of voltage frequency control
in this section.
