Marked Point Alignment Method I - Mitsubishi Electric C70 Setup Manual

7.3.3.3 Marked Point Alignment Method I

This is a method to align to the marked point (matchmark or marking line) on the machine. Use GOT project controlled by
sequence programs, switches on the machine operation panel, manual handle, and the [ABS. POSITION SET] screen in
the CNC monitor on GOT for the absolute position zero point initialization set. The GOT project and panel switches are
made by the machine tool builder.

The parameter "#2059 zerbas" decides the absolute position basic point.
(1) Display [ABS SERVO MONITOR] screen from [TOOL PARAM].
(2) Select the direction of the grid point just before the marked point of Marked Point Alignment Method I with "#2050
absdir Base point of Z direction". (0: Forward direction 1: Reverse direction)
(3) Select the absolute position basic point with the parameter "#2059 zerbas Select zero point parameter and basic
point".
