(7) Zero pass signal (M2406+20n) ..................................... Status signal
This signal turns on when the zero point is passed after the control circuit power

However, in the home position return method of proximity dog method, count
method, dog cradle method, limit switch combined method, scale home position
signal detection method, or dogless home position signal reference method, this
signal turns off once at the home position return start and turns on again at the
next zero point passage.
