5 Servo Adjustment
Always perform < Initial implementation > before performing the following adjustment items.
*Adjust according to (a), (b) or (c)
(a) Decrease SV106 by "10"
(b) Decrease SV112 by "1000"
(c) Increase the time constant
CAUTION
1. Always set the same value in the scale model gain of the interpolation axes when OMR-FF function is enabled.
2. Perform the above confirmation of accuracy in G61.1(G8P1)(high-accuracy) mode; use the constant and filter for high-
accuracy mode with OMR-FF function.
Note that only #2010: fwd-g (Feed forward gain) will be disabled.

In the state where
OMR-FF function is enabled
- SV106(PGM) =33
- SV112(IFF) = 10000
Measure the following with Waveform measurement
