controller
PID control, PI control, P control, and PD control can be selected.
Gain switchover by tension feedback is available.
Gain switchover by external terminal input is available.
Parameter setting / analog terminal input / pulse train input / communication
Use an analog terminal for the signal input. (Terminal 1, 2, 4, or 6 is selectable.)
Material break detection function
Set a taper ratio.
Set the compensation for acceleration and deceleration individually using external
signals.
Straight movement (with five break points) against the speed can be performed.
