Subindex 1:
PPI (min. movement): Current amplitude
Adjustment of the current amplitude in percent
• For large machines and high mass inertia values or for linear direct drives, the current amplitude usually has to
be increased.
• A Lenze setting of "100 %" corresponds to 35 % of the rated motor current (
for axis B).
Note!
If the current amplitude is set to > 400 %, the device utilisation (Ixt) monitoring and/or one of the motor monitoring
functions may respond and cause the abort of the pole position identification.

Subindex 3:
PPI (min. movement): Gain
Adjustment of the proportional gain of the PI controller
• With the Lenze setting "0", the PI controller works as an I-controller.

Subindex 4:
PPI (min. movement): Reset time
Adjustment of the PI controller reset time
• For this, observe the following setting details:
• In order to be able to compensate a positional variation faster, first the reset time should be reduced. If this
does not result in the desired behaviour, the proportional gain can be increased.
• Ensure that the position control does not get unstable. We therefore recommend to use an I controller.
