MotionSuite™ MP940 Machine Controller Reference Manual Parameter Details
6-13
21 Gear Ratio (Motor) Parameter that sets up gear ratio between the motor and load.
Set up the following 2 values in the configuration so that if
motor axis rotates m rotations, then load axis rotates n rota-
tions.
Gear ratio (motor side) = m
Gear ratio (load side) = n
Setting Example
In the above diagram: Set Decel Ratio = n/m = 3/7~4/9 = 4/21
Then set: Gear Ratio (Motor Side) = 21
Gear Ratio (Load Side) = 4
1
22 Gear Ratio (Load) 1
23 Maximum Value of
Rotary Counter When a rotary axis is set, set the reset position upon 1 rotation.
This is disabled in the case of linear axes.
Setting range: 1 ~ 2 31-1 (Command Unit)
(Ex.) Reset at each 360 degree in a rotating unit.
