[4] Position loop gain and deceleration rate adjustment at coil changeovers
When using a coil changeover motor, the position loop gain and deceleration rate can be set for
each coil.
• Coil-specific orientation control position loop gain
Compensation magnification values are set for each coil by the SP119, SP120 and SP126
settings, relative to each coil's SP001 or SP002 position loop gain reference value. If a "0" is set,
the SP001 (SP002) setting is adopted.
SP119
Effective position loop gain (H-coil) = SP001 (SP002) ×

SP120
Effective position loop gain (L-coil) = SP001 (SP002) ×

<<Only for MDS-C1-SPM>>
SP126
Effective position loop gain (M-coil) = SP001 (SP002) ×

• Coil-specific orientation control deceleration rate
Compensation magnification values are specified for each coil by the SP121, SP122 and
SP127 settings, relative to each coil's SP006 deceleration rate reference value. If a "0" is set,
the SP006 setting is adopted.
