5 DATA USED FOR POSITIONING CONTROL

MELSEC-Q

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

0 ≤	Backlash compensation amount	≤ 255
	Movement amount per pulse
