PARAMETER DESCRIPTION 258
5.11.9 Dwell function
V/F
During acceleration /deceleration, this function can solve the
backlash problem caused by stopping acceleration
/deceleration, through frequency and time set by this parameters.

Backlash compensation (10-18(
P.229
)=”1”)
The gears in reducer have backlash, and there is no-load segment between forward and reverse rotation.
Even if
the motor is running, the backlash will not produce a mechanical following status.
In order to avoid backlash, acceleration and deceleration will be temporarily stopped.
The frequency and time for
interrupting acceleration and deceleration are set from 10-18(
P.229
)~10-22(
P.233
).

Note: After setting backlash compensation, only the interruption time in acceleration and deceleration time will become
longer.
Acceleration and deceleration interrupt waiting function (10-18(
P.229
)=”2”)
If 10-18(
P.229
)=”2”, acceleration/deceleration stop function is enabled. When accelerating to the frequency set in
10-19(
P.230
), accelerate to the target value after waiting for the time set in 10-20(
P.231
). When decelerating to the
frequency set in 10-21(
P.232
), decelerate to the target value after waiting for the time set in 10-22(
P.233
).
