290 Parameters
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.

0.00…50.00%
Voltage boost at zero speed in percent of nominal motor
voltage.
1 = 1%
Motor model
temperature
adaptation
Enables the motor model temperature adaptation. Estimated
motor temperature can be used to adapt temperature
dependent parameters (e.g. resistances) of motor model.
Disabled
Temperature adaptation disabled.
0
Estimated
temperature
Temperature adaptation with motor temperature estimate
(parameter
).

Selects the form for the
U

f
(voltage to frequency) ratio below
field weakening point. For scalar control only.
Note:
The U/f function cannot be used with energy

is ignored.
Linear
Linear ratio for constant torque applications.
0
Squared
Squared ratio for centrifugal pump and fan applications.
With squared U/f ratio the noise level is lower for most
operating frequencies. Not recommended for permanent
magnet motors.
