7.2.1.2 Dog-type Reference Position Return Adjustment Procedures
Adjust the dog-type reference position return with the following steps.
(Note)
This adjustment is available when the sequence programs for machine control are installed in PLC CPU so
that the CNC servo axis can be operated.
(1)
Select [TOOL PARAM] ---> [MENU (MENU 5)] ---> [SETUP (MENU 4)] ---> "Y" ---> "INPUT" --->[AXIS]. Scroll the
page to display the [ZERO-RTN PARAM] screen.
(2)
Set "0" for the following parameters on the [ZERO-RTN PARAM] screen.
Reference position shift amount (#2027 G28sft)
Grid mask amount (#2028 grmask)
(3)
Turn the power OFF and ON, and then execute reference position return.
(Note)
Use the GOT project, controlled by sequence programs, or the switches on the machine operation panel
to command "reference position return mode" and operate the axis movement. The GOT project and the
panel switches are made by the machine tool builder.
(4)
Select [ALARM/DIAGN] --> [SERVO (MENU 2)]. Scroll the page to display the [SERVO MONITOR(3)] screen.
