Input signal is from overtravel (OT) preventive limit switch placed at machine moving direction end.
Both signals are always valid except for in torque control.
When the input signal turns off, motor rapidly decelerates to a stop in negligence of the rotation command in the detecting direction.
Motor can rotate by pulse train input in the direction opposite to detecting direction, or by manual feed (forward command or reverse
command).

While [+OT] (7) control input signal is off, the +OT detection (38) output signal is on. While [-OT] (8) control input signal is off, the -OT
detection (39) output signal is on.
