Backlash Compensation
Section 10-7
• After Backlash Compensation
Backlash compensation is applied for the first operating command that
operates in the opposite direction from which backlash compensation was
previously applied. Once backlash compensation has been applied, it will
not be applied again as long as operation is continued in the same direc-
tion.
Note
The PCU's present position compensation according to the backlash compen-
sation function is applied to both the feedback present position and command
present position.
10-7-3 Backlash Compensation Data Settings
When a G-series Servo Drive or a W-series Servo Drive is connected, the
data settings for backlash compensation are as follows:
Servo Parameter Area
Backlash Compensation Parameters (R88D-GN
@
-ML2)
The backlash compensation amount is set in Pn101 in command units. The
minimum setting unit for the backlash compensation amount, however,
depends on the encoder resolution.
