0 to 400Hz (Pr. 273 1/2)Hz to (Pr. 273 )Hz can be
achieved.

(Pr. 5 1/2)Hz to (Pr. 5 )Hz is achieved.
Set the time constant of the primary delay
filter relative to the output current.
(The time constant [ms] is 0.75
1 to 4000
and the initial value is 12ms.)
A larger setting provides higher stability but
poorer response.

Usually set a value between 130% and
180%.
0 to 1000%
Set the force (holding torque) for stop-on-
contact control.
9999 No compensation.
Set a PWM carrier frequency for stop-on-
contact control.
