No. Name/Value
97.13 IR compensation
0.00...50.00%
Description
Defines the relative output voltage boost at zero
speed (IR compensation). The function is useful in
applications with a high break-away torque where
vector control cannot be applied.

WARNING! Set IR compensation value as low as
possible. Large IR compensation value can lead
to overheating of the motor and damage to
the drive, if operated for longer periods at low
speed.
