Range : 1~65535
Unit : None
Authority : Operation admin or higher
Default : 1
Effective time : Instant
Note : When screws of different pitches and motors of different step angles or servo
motors of different pulses are matched, or connected through gears, it allows
keeping the program and actual motion distance consistent through electronic
gear ratio setting of the system.
CMR/CMD =P/ (L×1000)
CMR: gear ratio numerator
CMD: gear ratio denominator
P: Pulses corresponding to one rotation of the motor
L: Machine tool movement corresponding to one rotation of the motor (mm)
CMD/CMR is the pulse equivalent actually, i.e. the motion distance
corresponding to every pulse (unit: 0.001mm).
Ex 1: the motor rotates one cycle every 5000 pulses, and the machine tool moves
5mm when the motor rotates one cycle, then
CMR/CMD=5000/ (5*1000)=1/1
Then, CMR=1, CMD=1, the pulse equivalent is 0.001mm
Ex 2: the motor rotates one cycle every 5000 pulses, and the machine tool moves
10mm when the motor rotates one cycle, then
CMR/CMD=5000/ (10*1000)=1/2
Then, CMR=1, CMD=2, the pulse equivalent is 0.002mm
