For application encoders, a gear transmission between the application encoder and
motor must be parameterized via a gear factor (see chapter 8.4.11 "Gear factor speed
sensor 2").
The conversions between the different reference systems are done automatically, the
user sets the target values in user units referred to the distance.

8.4.13.1 Example

For parameterization of a linear slide, the following properties are known:
Motor gear ratio: 8:5
Application encoder gear ratio: 7:3
Feed rate of linear axis: 635.5 mm/revolution of the output shaft
This results in the following parameterization:
Feed constant
Gear shaft turns
Gear motor turns
EC2 Gear Factor Numerator
EC2 Gear Factor Denominator
In order to move by 1 mm, a positioning order of 10 u must be executed.

Parameters
Description
1115 = 6535 rev
1116 = 5
1117 = 8
513 = 24
514 = 35
In the case of linear systems, the feed constant is typically specified in
the data sheet. If this value is unknown, it must be determined empirical-
ly. For empirical determination of the feed constant, refer to application
manual "Positioning".
