Index Parameter Min Max Unit Default Cust ID Description
P2.10.8
Minimum fre-
quency for open
loop torque con-
trol
0.00 P2.1.2 Hz 3.00 636
The output fre-
quency limit below
which the drive
operates in the
frequency control
mode.
P2.10.9
Torque controller
P gain
0 32000 150 639
Gives the P gain
for the torque con-
troller in the open
loop control mode.
The P Gain value
1.0 causes a 1 Hz
change in the out-
put frequency
when the torque
error is 1% of the
motor nominal tor-
que.
P2.10.10
Torque controller
I gain
0 32000 10 640
Gives the I gain for
the torque control-
ler in the open loop
control mode. The
I Gain value 1.0
causes the inte-
gration to reach
1.0 Hz in 1 second
when the torque
error is 1% of the
motor nominal tor-
que.
