Parameters
Code
Positioning mode selection.
OFF： Needle up and down is adjusted by external synchronizer, and needle bar upper dead point is adjusted by
【183.PUB】
A： Needle up is adjusted by 【179.PUA】, and needle down is adjusted by【181.PDA】.
B： Needle up is adjusted by 【179.PUA】, needle down is adjusted by【181.PDA】
and needle bar upper dead point is adjusted by 【183.PUB】.
C： When pedal control, needle up is adjusted by【179.PUA】, needle down is adjusted by【184.PDB】,【185.PDC】 ;
