8.1.5
Stopper type (2) Mechanical zero return operation
This mechanical zero return method (creep speed only) uses only the stopper.
→
For the zero return interlock function, refer to Subsection 7.9.10
→
For details on the table operation, refer to Chapter 10
→
For the parameters, control data and monitor data, refer to Chapter 11
1. Operation
1) Upon the rising edge (OFF
→
ON) of the mechanical zero return command, the work piece moves in the
zero return direction at the zero return speed (creep).
2) After the work piece hits the stopper, the work piece stops when the servomotor torque reaches the zero
return torque limit value.
3) After the stop point, the current address is set as the mechanical zero-point address in the positioning
parameters.
4) The 20SSC-H turns the positioning completion flag ON and sets (turns ON) the zero return complete flag.

For the parameters, control data and monitor data, refer to Chapter 11
