C type machine zero return process
A: Select the Machine Zero mode, press manual positive or negative (zero return direction set
by bit parameter No.183) feed key, the corresponding axis will move to the zero at a high
speed(set by parameter No.113).
B: As the proximity switch touches the tongue for the first time, the deceleration signal is active.
The speed doesn’t slow down and it traverses on.
C: As the proximity switch detaches the deceleration switch, deceleration signal contact is
closed, the feed speed decelerates to zero, then it runs reversely by low return speed.
D: As the proximity switch touches the deceleration switch for the second time in reverse
running, deceleration signal contact is cut off, it still runs by low return speed; as it detaches
the deceleration switch, deceleration signal contact is closed again, so the movement stops.
The zero return indicator for the corresponding axis on the panel lights up for zero return
completion.
