Parameters 289
Sets the frequency at which IR compensation (set by
parameter
) reaches 0 V. The unit
is % of motor nominal frequency.
IR compensation
When enabled, IR compensation provides an extra
voltage boost to the motor at low speeds. Use IR
compensation, for example, in applications that require a
high breakaway torque.

Motor values supplied by the user that are used in the
motor model.
These parameters are useful for non-standard motors, or
to just get more accurate motor control of the motor on
site. A better motor model always improves the shaft
performance.

Notes
:
• Parameter value is automatically set to zero when ID
run is selected by parameter
.
The values of parameters
are then
updated according to the motor characteristics
identified during the ID run.
• Measurements made directly from the motor terminals
during the ID run are likely to produce slightly different
values than those on a data sheet from a motor
manufacturer.
• This parameter cannot be changed while the drive is
running.
