The conveyer belt load has
Here,
Electronic gear ratio( N ) = Pt

ΔP
For example:
Known the encoder line number C=2500 line, the reducer gear ratio 1/10, the rolling cylinder diameter
D=200mm, a pulse travel equivalent ΔP=0.001mm, Calculate the electronic gear ratio.
Calculation step:
z Calculate the resolution of the encoder (Pt)
Pt = 4 × C = 4 × 2500 = 10000( pulse / rev)
z Calculate the command pulse numbers for one turn of the load shaft (Pc)

=
62800
z Calculate the electronic gear ratio
Electronic gear ratio( N ) = Pt = 10000 = 100000 = 2500
M Pc × R 62800 × (1/10) 62800 157
z Set parameters (By first numerator as an example)
Numerator N=2500，denominator M=157，set P029=2500 and P030=157.
