The dimensional reference to the master is established via the following settings:
 Travel path per motor revolution master axis numerator = 50mm or with a rotary
feedback system: Travel per feedback revolution.
With denominator = 1 the value can be entered directly.
Long-term drift can be avoided by entering non-integral values integrally as a
fraction with numerator and denominator.
 Increments per revolution of the master axis
If required the direction of rotation of the master axis read in can be changed.
Example: Electronic gearbox with position detection via encoder
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:
Master_I Travel Distance per Master Axis revolution
(M_Units/rev)
MasterPos =
I_M

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.
