4.3.1 Master axis (master shaft)
For scaling and imaging the master value in the application, the machine parameters of
the higher-level drive (master shaft) must be set.

Master value scaling
Example of determining the machine parameters for the master axis
Note!
When setting (scaling) the electrical shaft, ensure that the ratio and encoder
constants are identical for all drives in the system. The reference to the scaling
of the master drive is sensible.

Value Unit
C03930 Gearbox ratio - numerator 1
C03931 Gearbox ratio - denominator 1

1. Set gearbox ratio for the master value in the form
of a quotient (numerator and denominator):
i
1
= 3.333 = 10/3
– Numerator (C03930) = 10
– Denominator (C03931) = 3
2. Set feed constant (C03932).
– For the master value: Vk = d
1
* π = 471.2389 mm
3. Set the selection "mm" as path unit (C03933).
4. As reference speed (C03941) set the max. machine
speed v
max
= "1000 mm/s".
