260 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.

3.50%
0.00…50.00%
Voltage boost at zero speed in percent of
nominal motor voltage.
1 = 1%
Selects the form for the
U
/
f
(voltage to
frequency) ratio below field weakening point. For
scalar control only.
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.
1
Enables or disables the DC bus voltage stabilizer.
Disabled
DC bus voltage stabilizer disabled.
0
Enabled min
DC bus voltage stabilizer enabled, minimum
stabilization.
50
Enabled mild
DC bus voltage stabilizer enabled, mild
stabilization.
100
Enabled
medium
DC bus voltage stabilizer enabled, medium
stabilization.
300
Enabled strong
DC bus voltage stabilizer enabled, strong
stabilization.
500
No.
