• Save the zero-point position offset as follows:
Saving to the M Register in Ladder Programs
Calculate (- (machine coordinate calculation position monitor) + zero-
point position offset setting), and save to the M register at the same time
as storing into OLxx06.
Save the content stored in the M register into setting parameter OLxx06
“Zero-point Position Offset” at power restart or servo power ON.
The program necessary for linear axis abs system linear axis is as follows:

TM parameter screen
After execution of zero-point setting, set the value (current value) of the
zero-point position offset (OLxx06) and save to the controller by the
