(Note)
This parameter is available only when you use High Resolution Serial Output
Circuit H.
Changing this parameter occurs P/S alarm 000 (PLEASE TURN OFF POWER).
When you set this parameter, detection unit at FFG=1/1 is (Signal pitch /128[um]).
Please use(Signal pitch/128[um])for the parameter calculation of the number
of position pulses and FFG. If you need minimum detection unit (Signal pitch
/512[um]), please set FFG=4/1.
When you use nano-interporation, all position feedback pulses from separate
sclase is used as decimal position feedback.
