DOG type mechanical zero return

With the DOG type mechanical zero return, the 20SSC-H sets the zero-point position after the module stops
with a near-point DOG signal and servo motor zero-point signal. Use the DOG search function to execute the
DOG type mechanical zero return arbitrarily.
1. Operation
Zero return starts as follows, at the rising edge (OFF

1) At the rising edge (OFF
zero return direction at the zero return speed (high speed).
2) At the DOG input, the 20SSC-H decelerates the work piece to the zero return speed (creep).
3) The 20SSC-H counts zero-point signals after passing the zero-point signal count start timing.
4) After counting the specified number (zero-point signal numbers), the 20SSC-H stops the work piece.
5) After calibrating the zero-point, the current address is set as the mechanical zero-point address in
positioning parameters.
6) The 20SSC-H turns the positioning completion flag ON and sets (turns ON) the zero return complete flag.
