Xinje DS2-21P5-AS - Electronic Gear Ratio

39
t1, t2 ≤0.1μs
τ≥ 2.5μs
(τ/T) × 100 = 40%～60%
5-3-3. Electronic gear ratio
The electronic gear function is set any value for motor moving quantity corresponding to
input pulse command. The host device which sends command doesn’t need to consider the
machine deceleration ratio and encoder pulse quantity.

1. Calculate the electronic gear ratio (B/A) using the following steps:
Step
Content
Explanation
1
Confirm the machine
specification
Confirm the deceleration ratio, ball screw distance, pulley
diameter
2
Confirm the encoder
pulse
Confirm the servo motor encoder pulses
3
Set the reference unit
Set the actual distance or angle corresponding to 1 pulse of the
command controller
Workpiece
Ball screw pitch: 6mm
Encoder pulse: 2500
Define the machine condition and command unit by
electronic gear
The workpiece moves 10mm
Command unit is 1 µm
10mm
1µm
=10000 pulse
Command unit: 1µm
Encoder pulse: 2500
Ball screw pitch: 6mm
Workpiece
The workpiece moves 10mm
One rotation is 6mm
10
÷
6=1.6666
2500×４ pulse finishes one rotation
Command input 16666 pulses
Calculate these values in the host controller
