STOP
Functions
This is the emergency stop signal. If input occurs during drive operations, the motor
decelerates at its maximum rate, and goes into the servo OFF state. After clearing the
signal, once the motor is stopped and at least 200ms have elapsed, the servo will go into
the ON state.

* Canceling the STOP signal is only possible after the motor has
completely stopped and 300ms have elapsed.
* When the STOP is cancelled, the interlock turns OFF, and if an ALM is
not issued, automatically changes to servo ON status.
* STOP signal cancel (detection of Active→Non-Active edge) cancels
STOP commands set remotely via transmission as well.
* Changing to STOP status can be initiated via transmission or the
STOP input port.
Alarm clear signal for alarms that can be cancelled.
