feedback
torque control
Control method
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.
Tension command
Parameter setting / analog terminal input / pulse train input / communication
Tension detection signal
Use an analog terminal for the signal input. (Terminal 1, 2, 4, or 6 is selectable.)
Additional function
Material break detection function
Taper function
Set a taper ratio.
Inertia compensation function
Set the compensation for acceleration and deceleration individually using external
signals.
Mechanical loss compensation
function
Straight movement (with five break points) against the speed can be performed.
