Torque compen-
sation gain
Sets the torque compensation
gain.
Usually changing this setting is
not necessary.
Adjust it under the following
circumstances:
• When the cable is long
increase the set value.
• When the motor capacity is
smaller than the Inverter
capacity (Max. applicable
motor capacity), increase the
set values.
• When the motor is oscillat-
ing, decrease the set values.
Adjust the torque compensation
gain so that at minimum speed
the output current does not
exceed the Inverter rated output
current.
Do not change the torque com-
pensation gain from its default
(1.00) when using Open Loop
Vector control.
