PS6.2.3 Calculate pulse equivalent according to fixed electronic gear ratio
DELTA ASDA-B2: Electronic gear ratio default--16/10
，
A2: Electronic gear ratio default--N=128/10
E.g. B2
：
Set P1-44=1, P1-45=1, Encoder pulses equivalent 2500×4=10000
Screw drive
screw pitch=5mm
，
pulse equivalent =
= 2000
