< Setting method >
(1) Disable all the input compensation parameters before checking the torsion amount with the motor-end
feedback in the roundness measurement.
Set lost motion compensation 1 (LMC1) to "0".
Set lost motion compensation 2 (LMC2) to "0".
Set lost motion compensation 3 spring constant (LMCk) to "0".
Set lost motion compensation 3 viscous coefficient (LMCc) to "0".
Set lost motion compensation 4 gain (LMC4G) to "0".
Set full-closed torsion compensation control torsion amount (FCTC) to "0".
(2) Perform "Roundness measurement" with NC Analyzer2 waveform measurement function.
Set radius R to about 100mm and feedrate F to about 3000mm/min.
Select "Setting" from the measurement screen and change Waveform type, which is in Channel setting
on "Sampling condition setting", from "Position FB" to "Motor end position".
