The reference to the master axis is established via the increments per revolution
and the travel path per revolution of the master axis (corresponds to the
circumference of the measuring wheel).
That is:
MasterPos =
Master_I
*
Travel Distance per Master Axis revolution
(M_Units/rev)

I_M
Travel Distance per Master Axis revolution -
Denominator
MasterPos: Master Position
Master_I: master increments read in
I_M: Increments per revolution of the master axis
Encoder with 1024 increments per master revolution and a circumference of the
measuring wheel of 40mm.
Travel path per revolution of the master axis numerator = 40
Travel path per revolution of the master axis denominator = 1
Increments per revolution of the master axis = 1024
Reference system of Slave axis: Unit of measure [mm]
Travel path per revolution numerator = 1
Travel path per revolution denominator = 1
Gearing numerator = 2
Gearing denominator = 1
This results in the following interrelations:
If the measuring wheel moves by 40mm (1 master revolution), the slave axis will
move by 80mm.
