Control Commands (cont'd)
Coordinates Setting
Note: It can be dangerous to execute this command carelessly to switch the coordinates of the
reference position. After executing this command, confirm that the reference position
and the new coordinates are in agreement before starting 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 completed.
• 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 supply is turned OFF.
Normally, this command is executed once during system setup and it is not necessary to exe-
cute it again. Each time that the command is executed, 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 supply OFF and then ON
again before executing the command.
