8.3 Backlash Compensation Function
The backlash compensation function compensates for the backlash amount in the
mechanical system. When the backlash compensation amount is set, extra pulses
equivalent to the backlash compensation amount are output after a change in
travel direction resulting from positioning control, JOG operation, or manual pulse
generator operation.

.1 Backlash Compensation Amount
(1) Setting the backlash compensation amount
The backlash compensation amount is one of the fixed parameters, and is set
for each axis using a peripheral device.
The setting range differs according to whether mm, inch, degree, or pulse units
are used, as shown below.
(a) Millimeter units
• 0 to 6553.5
(Backlash compensation amount)
• 0 ≤
(Travel value per PULSE)
≤ 65535(PLS)
(Decimal fraction rounded down.)
(b) Inch or Degree Units
• 0 to 0.65535
(Backlash compensation amount)
• 0 ≤
(Travel value per PULSE)
≤ 65535(PLS)
(Decimal fraction rounded down.)
(c) Pulse Units
• 0 to 65535
(Backlash compensation amount) ×(PULSES per
rotation)
• 0 ≤
(Travel value per rotation)
≤ 65535(PLS)
(Decimal fraction rounded down.)
