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, the 20SSC-H writes the mechanical zero point address, specified in positioning
parameters, to the current address.
4) The 20SSC-H turns the positioning completion flag ON and sets (turns ON) the zero return complete flag.
3. Setting item
In the stopper type mechanical zero return, specify the following settings.
Setting item
Zero return mode
Zero return speed (high speed)
Zero return speed (creep)
Zero return direction
Selection of DOG input
DOG input logic
Mechanical zero-point address
Zero return torque limit
4. Changing the zero return speed
Use the override function or operation speed change function to change the zero return speed (high speed).
However, the speed does not change when the operation speed change disable flag is ON.
