Confirm the
command unit
1 command unit: 0.001mm
1 command unit: 0.1°
1 command unit: 0.02mm

Calculate the
command
amount of 1
revolution of
load shaft
6mm/0.001mm=6000
360/0.1=3600
314mm/0.02mm=15700
5
Calculate the
pulse number
m of one
revolution of
motor shaft
M =6000/(1/1)=6000
M=3600/(3/1)=1200
M=15700/(2/1)=7850

Set pulses per
rotation
P0-11/P0-12
P0-11=6000
P0-12=0
P0-11=1200
P0-12=0
P0-11=7850
P0-12=0
Set electronic
gear ratio
(P0-13/P0-14)/
(P0-92~95)
P0-13=131072
P0-14=6000
After reduction
P0-13=8192
P0-14=375
P0-13=131072
P0-14=1200
After reduction
P0-13=8192
P0-14=75
P0-13=131072 P0-14=7850
After reduction
P0-13=65536 P0-14=3925
Conver to second gear ratio
P0-92=5536 P0-93=6
P0-94=3925 P0-95=0
5.3.1.2 Positioning completion signal (/COIN, /COIN_HD)
In position control, the signal indicating the completion of servo motor positioning is used when the
command controller needs to complete positioning confirmation.
