to

Depend 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 and
deceleration ratio is 1:1; so the
numerator of the electronic
gear ratio is 8, and the
denominator is 5. (Select an
incremental type encoder)
