ABS Encoder Origin Setting
Section 8-6
Execute ABS origin setting using the bit in the PC Interface Area.
• The absolute position setting value is stored in the system variable after
ABS origin setting is completed. It is possible to transfer the absolute
position setting value to another MC Unit through backup/restore opera-
tion using the CPU Unit’s memory card.
• The absolute position setting value can be referenced using IORD
instruction or the Support Tool. However, they cannot be edited directly.
Make sure to set the absolute position setting value using ABS origin set-
ting function.
• The addresses in the table below are for Axis 1:
Note
(1) It is recommended to backup the contents of ABS origin setting in the
CPU Unit’s memory card after ABS origin setting is completed.
(2) Make sure to set the absolute position setting value correctly. Otherwise,
difference in values for positioning will occur between the MC Unit and
ABS encoder.
(3) Do not execute ABS origin setting at least for one second after the main
power supply for the Servo Driver or control power supply is turned ON.
