S-curve
characteris-
tic time at
accelera-
tion start
When the S-curve characteristic time
is set, the accel/decel times will
increase by only half of the S-curve
characteristic times at start and end.
The S-curve characteristic time at
start and end of deceleration is fixed
to 0.2 sec and can not be changed.

Torque com-
pensation
gain
Sets torque compensation gain as
a ratio.
Usually setting is not necessary.
Adjust in the following circum-
stances:
• When the cable is long;
increase the set value.
• When the motor capacity is
smaller than the Inverter capac-
ity (Max. applicable motor
capacity), increase the set
values.
• When the motor is oscillating,
decrease the set values.
Adjust the output current range at
minimum speed rotation so that it
does not exceed the Inverter rated
output current.

The torque compensation delay
time is set in ms units.
Usually setting is not necessary.
Adjust in the following circum-

• When the motor is oscillating,
increase the set values.
• When the responsiveness of the
motor is low, decrease the set
values.
