Stopper type (1) mechanical zero return operation

This mechanical zero return method uses the DOG signal and stopper.
High speed travel is possible up to the DOG signal, thus reducing the time for mechanical zero return.

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 work piece hits the stopper, and the work piece stops when the servomotor torque reaches the zero
return torque limit value.
4) After the stop point, the current address is set as the mechanical zero-point address in the positioning
parameters.
5) The 20SSC-H turns the positioning completion flag ON and sets (turns ON) the zero return complete
flag.
