(1) [Pr.11] Backlash compensation amount
The error that occurs due to backlash when moving the machine via gears can be compensated.
When the backlash compensation amount is set, pulses equivalent to the compensation amount will be output
each time the direction changes during positioning.
• The backlash compensation is valid after machine OPR. Thus, if the backlash compensation amount is set
or changed, always carry out machine OPR once.
• The backlash compensation amount setting range is 0 to 65535, but it should be set to 255 or less by using
the following expression.
