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.
