If you set PnB54 to 1 (Enable Expansion Mode), the parameter setting range, the command name, and the com-
mand setting range will change. Refer to the following section for details.

Function/Description
Coordinates Setting
Note: It can be dangerous to execute this command carelessly to switch the coor-
dinates of the reference position. After executing this command, confirm that
the reference position and the new coordinates are in agreement before start-
ing operation.
Setting range: −99999999 ≤ nnnnnnnn ≤ +99999999 [Reference units]
• With an Incremental Encoder
Replaces the current position with nnnnnnnn.
Homing will be completed and the software limits (PnB21 and PnB23)
will be enabled.
This coordinates setting will be cleared when the control power supply is
turned OFF.
Note: Parameter PnB25 will not be refreshed. PnB25 will be used as the current
position when the control power supply is turned ON and homing is com-
pleted.
• With an Absolute Encoder
Switches the current position to nnnnnnnn and refreshes PnB25 with the
absolute position offset so that the current position becomes nnnnnnnn.
The coordinates setting will remain effective after the control power sup-
ply is turned OFF.
Normally, this command is executed once during system setup and it is
not necessary to execute it again. Each time that the command is exe-
cuted, the content of PnB25 is refreshed and stored in EEPROM, so this
command must not be executed repeatedly or too frequently.
Note: When one of the Pn20E to Pn210, Pn205, or PnB20 to PnB25 parameters
has been changed, enable the new setting by turning the control power sup-
ply OFF and then ON again before executing the command.
