22,Using Electron Gear Ratio for Feeding Axes [0:Yes, 1:No]
It is for whether using the electron gear ratio for feeding axis. 0: yes,using electron gear, 1: No,
don’t using electron gear.
23,Numerator of X_Electron Gear (X_CMR) 24,Denominator of X_Electron Gear(X_CMD)
25,Numerator of Y_Electron Gear (Y_CMR) 26,Denominator of Y_Electron Gear(Y_CMD)
27,Numerator of Z_Electron Gear (Z_CMR) 28,Denominator of Z_Electron Gear (Z_CMD)
29,Numerator of A_Electron Gear (A_CMR) 30,Denominator of A_Electron Gear(A_CMD)
These are set for electric ratio of feeding axes,which are composed by Numerator &
Denominator of Feeding-axis electron gear ratio. Also CMR/CMD, Range: 1-999999.

Explain: When lead screws with different screw pitches are configured with motors of various step
angles,or with servo motors of different pulse number per round,or connections are realized through
different gears,the programmed values can remain consistent with the actual moved distance by
setting the parameter of the electronic gear ration of the system.
Electron Gear Ratio = = =
CMR:Numerator of gear ratio
CMD:Denominator of gear ratio
P: pulse number per motor round
L: Moved distance per motor round(mm)
The value of CMD/CMR is pulse equivalent,also moving distance per pulse ,with unit is 0.001mm.
Example1: Motor rotates one circle very 5000 pulses,after machine tool moves 5mm,then:
CMR/CMD = 5000 / (5 * 1000 ) = 1/ 1
That is to say,we can set the values as :CMR=1,CMD=1.
Here ,the pulse equivalent is 0.001mm.
Example2: motor rotates one circle very 5000 pulses,after which the machine tool moves 10mm.
CMR/CMD = 5000 / (10 * 1000 ) = 1 / 2
That is to say,we can set the values as :CMR=1,CMD=2.
Here ,the pulse equivalent is 0.002mm.
There is one simple solution,for example,current ratio is 1:1,X0-X10(CNC move 10mm),check
real distance that machine tool moves,if machine just move 5mm, set to 10:5, if machine moves
12mm, set to 10:12.also P27=10, P28=12 on Axis parameter.
31,Type of Limit Switch in Positive Direction[0:NO type, 1:NC type]
It is set type of limit switch in positive direction, also type of switch that is connected to
+L,PIN16_CN3 plug. 0:NO Type, 1: NC Type.
32,Type of Limit Switch in Negative Direction[0:NO type, 1:NC type]
It is set type of limit switch in negative direction, also type of switch that is connected to
-L,PIN15_CN3 plug. 0:NO Type, 1: NC Type.
33,Type of Home [D3X;D4Y;D5Z;D6A;D7B 0:Switch; 1:float Zero]
It is set type of home. bit parameter. Each axis set alone.
Bit D7 D6 D5 D4 D3 D2 D1 D0
Value 0 0 0 0 0 0 0 1
Axis B A Z Y X - - -
0: Switch/Sensor for home, 1:Float Zero point for home.
