C80 Series Connection and Setup Manual
14 Setting the Position Detection System
*2 The operation order is slightly different when "#2059 zerbas = 1 (grid point just before stopper)" is set. Set the
procedure (6) "Zero-P" after "Complete" is displayed on "State" of the procedure (12).
Automatic initialization start point
"Basic machine
coordinate system zero
point"
Zero return parameter
"#2037 G53ofs"
- (8) to (12) in this diagram correspond to the operation procedure.
- Select either one of "#2 Zero-P" with the parameter.
(Note 1) To change just the basic machine coordinate zero point, set "#0 Absolute posn set" and "#2 Zero-P", and then
turn the power OFF and ON.
(Note 2) If pressing against the machine end is attempted without passing the grip point once after turning the power
ON, the operation message "Not passed on grid" will appear. Return to a point before the last grid, and then
repeat from step of pressing against the machine end stopper.
(Note 3) If the first grid point is covered by the grid mask (#2028 grmask) as a result of return to the electric basic
position, the axis stops at the next grid point.
Note that zero-point shift amount (#2027 G28sft) is invalid.
(Note 4) Acceleration/deceleration during movement at the specified push speed is performed in smoothing-off
(stepfeed) mode.
(Note 5) If "0" is specified for "#2056 aproch" of the absolute position parameters, the machine zero point is regardedas
the approach point.
(Note 6) Automatic initialization is interrupted if one of the following events occurs. If it is interrupted, [State] indicates
"Jog Start" (after selecting the "Auto init set" mode if it is caused by mode change), so restart operation from
the step of JOG-start.
- An absolute position detection alarm occurs.
- Operation preparation signal turns OFF.
- The mode is changed.
- The system is reset.
If [State] is "Complete" before automatic initialization is started, "State" returns to "Complete" when power is
turned OFF and ON again without restarting the operation.
