5.3 User-defined units
The controller supports the possibility to set user-defined units. It is thereby possible to set and read out the
corresponding parameters, e.g., directly in degrees [°], [mm], etc.
5.3.1 Calculation formulas for user units
5.3.1.1 Position information
All position values in open loop and closed lop mode are specified in the resolution of the virtual position
encoder. This is calculated from the virtual encoder increments (608F
h
:1
h
(Encoder Increments)) per motor
revolutions (608F

(Motor Revolutions)):

If value 608F

h

h
is set to "0", the controller uses "1" in subsequent calculations. The
factory settings are:
●
Encoder increments 608F
h
:1 = "2000"
●
Motor revolutions 608F
:2 = "1"
Example
h
:2
h
is set to the value "1", 608F
:1
h
is set to the value "2000" (default). Thus, the user
unit is 2000 increments per revolution. For a stepper motor with step angle of 1.8°, this
corresponds to the one tenth step mode.
