calculated deceleration ratio 1:1, pulse equivalent 0.001
mm,
CMX/CDV=10000×0.001/5 = 2/1;
When pulse unit = 0.0005mm, CMX / CDV = 1/1.
Electronic gear ratio range: 1/50 ~ 500

3: cumulative command pulses E: load inertia
When the parameter is set [3], monitor if the
number of sent and received pulse is correct by
setting this parameter. In Weihong control
system, the correct quantity of pulse sent by
control card is detected by pulse inspection to
determine if there is electrical interference.

external input;
[1]: servo on all the time inside.
Bit 1: last signal of positive rotation range (LSP):
[1]: auto servo on inside and no need of external
wiring.
Bit 3: last signal of negative rotation range
(LSN) :
[1]: auto servo on inside and no need of external

Command pulse numerator and denominator are also those of
the electronic gear ratio.
α / β=encoder resolution× pulse equivalent× mechanical
deceleration ratio / screw pitch.
Typical value: encoder resolution 65536, pulse equivalent
0.001, pitch 5mm, mechanical deceleration ratio 1,
α / β=65536×0.001 / 5=8192 / 625,
So α=8192, β=625. 02
