(2) Backlash compensation processing
The details of backlash compensation processing are shown in the table below.
Table 8.2 Details of Backlash Compensation Processing
Condition Processing
First motion after power on
• No backlash compensation if travel direction = zeroing
direction.
• Backlash compensation if travel direction ≠ zeroing direction.
JOG operation start
• Minimum backlash amount on first JOG operation after travel
direction change.
Positioning start • Backlash compensation if travel direction changed.
Manual PULSE generator
operation
• If travel direction changed.
Zeroing start
• Backlash compensation amount is valid after zeroing is
started.
Absolute position system
• Status stored at power off and applied to 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.
