Cn.15
PM speed
controller P
gain 2
100 0 – 5000
Adjust the proportional gain 2 of the speed
controller (high speed) for permanent
magnet synchronous motor control.
Note: Visible parameter if dr.9 = PM
Sensor-less
NO
Cn.16
PM speed
controller I
gain 2
150 0 – 9999
Adjust the integral gain 2 of the speed
controller (high speed) for permanent
magnet synchronous motor control.
Note: Visible parameter if dr.9 = PM
Sensor-less
NO
Cn.20
Sensorless
control gain 2
NO
NO
YES
Allows configuring the sensorless control
gain.
OPT. DESCR. FUNCTION
0 NO
Sensorless control gain
configuration parameters
will not be shown.
1 YES
Enables sensorless control
gain configuration.
Parameters Cn.21-32 will
be displayed.
YES
Cn.21
ASR
proportional
gain 1
(*)
0 to
5000%
Set the proportional gain 1 of the speed
controller (ASR).
The higher the proportional gain, the faster
the response will be. But if the gain is too
high, the speed of the motor might oscillate.
YES
Cn.22
ASR integral
time 1
(*)
10 to
9999ms
Set the integral gain 1 of the speed
controller (ASR).
YES
Cn.23
[18]
Independent
controller
proportional
gain 2
(*)
1.0 to
1000.0%
Set the proportional gain 2 of a separate
controller.
The higher the proportional gain, the faster
the response will be. But if the gain is too
high, the speed of the motor might oscillate.
YES
[18] Displayed when dr.9 is set to 4 (S-less1) and Cn.20 is set to 1 (YES).
(*) This value depends on the motor setting.
