5 DATA USED FOR POSITIONING CONTROL

1) The backlash compensation is valid after machine OPR. Thus, if the backlash

compensation amount is set or changed, always carry out machine OPR once.

2) The backlash compensation amount setting range is 0 to 65535, but it sh ould

be set to 255 or less by using the following expression.

Backlash compensation amount
0 ≤Movement amount per pulse ≤ 255
