Electronic
gear ratio
4/1
1/32767
to
32767/1
Depends on the specific encoder
resolution. The formula of
electronic gear ratio of servo
driver is as below:
Electronic gear ratio numerator
=mechanical deceleration ratio ×
4× pulse No. per encoder circle;
Electronic gear ratio denominator
= (screw pitch / pulse equivalent)
E.G. In Weihong system, the
default pulse equivalent is
0.001mm/p, screw pitch is 5mm,
pulse number per encoder circle
is 2000 shaft coupling direct drag,
currently the numerator of the
electronic gear ratio is 8, and the
denominator is 5. (Select
incremental type encoder)
