C4-01
Torque compensation
gain
Sets torque compensation gain as a
ratio.
Usually setting is not necessary.
Adjust in the following circum-
stances:
S When the cable is long; increase
the set value.
S When the motor capacity is small-
er than the Inverter capacity
0.00 to
2 50 1.00 B - 23 C4 01
Torq Comp Gain
er than the Inverter capacity
(Max. applicable motor capac-
ity), increase the set values.
S When the motor is oscillating, de-
crease the set values.
Adjust the output current range at
minimum speed rotation so that it
does not exceed the Inverter rated
output current.

Torque compensation
time constant
The torque compensation delay
time is set in ms units.
Usually setting is not necessary.
