(Max.
applicable motor

increase the set
values.
• When
the motor is oscil-
lating,
decrease the set
values.
Adjust
the output current
range
at minimum speed
rotation
so that it does not
exceed
the Inverter rated
output
current.
Do
not alter the torque com-
pensation
gain from its
default
(1.00) when using
