7-3-19 G54: CHANGE REFERENCE COORDINATE SYSTEM PV
Changes the present value in the reference coordinate system.
Format
G54_<present value ... >
Operands
The following table shows the possible settings for the operands.
Description
This command changes the present value of the specified axis reference
coordinate system to a specified value.
!Caution
The absolute value stored in the absolute encoder will not be changed by this
command. Unlock the servo, lock it again and read values to use the present
position in the absolute encoder.
A software limit exceeded error will occur if a specified value exceeds the soft-
ware limits set in the system parameters.
!Caution
If this command is executed just after a G01, G02, G03, or G32 command, the
interpolation will be performed in Stop Mode, not Pass Mode, even if Pass
Mode has been selected. The following example shows this effect.
Programming Example
In this programming example, the present value of the reference coordinate
system is changed from (300, 400) to (200, 200).
