Readjust constants of speed control system
(code F61 to F66, C30 to C34, C40 to C45,
C50 to C55, and C60 to C65).
You can increase ASR (P constant) of function code
to reduce overshoot/undershoot in general.
Motor presents hunting.
Adjust constants
of speed
control system.
NO
Motor speed fluctuates when load changes in large amount.
You can quicken response of speed control system
to reduce speed fluctuation.
Readjust constants of speed control system.
If you still cannot operate correctly, contact FUJI.
