5 Servo Adjustment
Measure the roundness and read the torsion amounts generated when the direction is reversed (linear
parts in the following figure). Set the smaller value of the read values to the parameter: SV206 (unit:
0.01μm) as the compensation amount.
Example: When the values are +X = 4.5μ m, -X = 4.2μ m, +Y = 3.9μ m, and -Y = 4.2μ m,
(3) Perform lost motion adjustment.
After setting the torsion amount (SV206), perform the lost motion adjustment (automatic) with NC
Analyzer2 adjustment function.
If requiring to improve the accuracy further than the adjustment result, adjust the lost motion
compensation amount.
Check the result in roundness measurement after adjusting the compensation amount.
【#2406】 SV206 FCTC Full-closed torsion compensation control torsion amount
Set the compensation amount of full-closed torsion compensation function.
Set the torsion amount between the motor-end position and the machine-end position right after the
stop as a standard setting value.
When not using, set to "0".
---Setting range---
0 to 32767 (0.01μm)
【#2316】 SV116 SSF11 Servo function 11
bit 1 : fctcfw Full-closed torsion compensation function forward direction
compensation enabled
Compensate the torsion amount in the forward direction with the full-closed torsion compensation
function. When compensating the torsion amount in the reverse direction only, set to "0".
