2.2 Control Commands
2 -33
* 1. Default setting: The current position is set as the machine coordinate origin when the power is turned
ON. If ZERO POINT RETURN is then not executed, the software limit switch function will not be
effective.
* 2. Yes: The machine coordinate origin is set using the position information in the absolute position de-
tecting encoder.
* 3. Cancelled: The previously set workpiece coordinate system is cancelled, and the workpiece coordi-
nate system is the same as the machine coordinate system.
For infinite-length axes, set a value within the range from 0 to POSMAX. If a value out of the setting range
is set for any infinite-length axis, an alarm will be generated.
2.2.4 COORDINATE PLANE SETTING (PLN)
J Overview
The COORDINATE PLANE SETTING (PLN) command defines two logical axes set in the pa-
rameters as a coordinate plane. Execute the PLN command before executing a command in
which a coordinate plane is specified.
Once designated, the coordinate plane remains in effect until it is redefined or until PROGRAM
END is executed.
J Description
The PLN command is designated as follows:
X-axis name Y-axis name
↓ ↓
PLN [axis1] [axis2] ;
Designate the two axes of the coordinate plane.
J Programming Examples
The following illustration shows a programming example for the PLN command.
