Parameters 283
97.13 IR compensation
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.
See also section IR compensation for scalar motor
control on page 36 .
Typical IR compensation values are shown below.
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.
