*1.The factory setting will change when the control method is changed. (V/f control factory settings are given.)
*2.The starting torque value can be set only for (-E) models.
nAdjusting Torque Compensation Gain
Normally, there is no need to make this adjustment. Do not adjust the torque compensation gain when using
open loop vector control.
For V/f control, adjust the torque compensation gain in the following circumstances.
• If the cable is very long, increase the set value.
• If the (maximum applicable) motor capacity is smaller than the Inverter capacity, increase the set value.
• If the motor is vibrating, reduce the set value.
Adjust this parameter so that the output current during low-speed rotation does not exceed the Inverter rated
output current range.

Tor que compensation gain
Set the torque compensation gain using the multi-
plication factor. Normally, there is no need to
change this parameter. Adjust the torque compen-
sation gain in the following circumstances.
•If the cable is very long, increase the set value.
•If the motor is smaller than the maximum
applicable motor of the Inverter, increase the
set value.
•If the motor is vibrating, reduce the set value.
Adjust this parameter so that the output current
during low-speed rotation does not exceed the
Inverter rated output current range.
