If no electronic greasing is used, the valuation will be as follows:
Since the screw distance is 3mm, i.e. when motor rotate one rev, the working load will move 3mm. if
moving distance 4mm is required, it is 4/3 of rev
Pulse Count Requirement
If motor per rev requires 10000 pulse, then
= 13333.33333…
pulses
It will leads to innite number with accumulative error in pulse number.
If use electronic gearing ratio
If 1 pulse is set to 1um, and 10000 pulse per rev, the Electronic gearing ratio can be set as follows:
If Electronic gearing ratio is set to , then 1 pulse send by the host, will leads to 1um movment on the
moving object.

7.2.6 Jerk Smoothing Filter
Applying dynamic lter on speed and direction signals can signicantly smoothing motor rotary motion,
and reduce damages towards mechanical layer.
Jerk smoothing lter e󰀨ects are as follows ：

Time
Target Curve
Actual Curve
T
1) The smaller value of P-07 (KJ), the strong e󰀨ect it will be.
2) Jerk smoothing lter will cause command delay time T, but it will not e󰀨ect
in position accuracy.
