TENSION SENSORLESS TORQUE CONTROL

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.
Dancer/tension control selection, Inertia compensation acceleration, Inertia
compensation deceleration, Inertia compensation second acceleration/
deceleration time selection, Winding diameter measurement, Stall mode trigger,
