Absolute position system
POINTS
(1) The feed pulses equivalent to the backlash compensation amount are not
added to the feed current value.
(2) Zeroing is required after the backlash compensation amount is changed.
The original backlash compensation amount is retained until zeroing is
carried out.
• No backlash compensation if travel direction = zeroing
direction.
• Backlash compensation if travel direction ≠ zeroing direction.
• Minimum backlash amount on first JOG operation after travel
direction change.
• Backlash compensation if travel direction changed.
• If travel direction changed.
• Backlash compensation amount is valid after zeroing is
started.
• Status stored at power off and applied to absolute position
system.
