Referencing

Referencing modes
When telegrams 7, 9, 110, and 111 are used, starting referencing can be configured with the
PROFINET control word STW1.11:
Control word
If the servo motor has an incremental encoder, totally three referencing modes are available:
● Setting reference point with the digital input signal REF
● External reference cam (signal REF) and encoder zero mark
● Encoder zero mark only
If the servo motor has an absolute encoder, the three referencing modes are available. You
can also adjust the absolute encoder (by setting current position as the zero position) with
the BOP function "ABS". Refer to Section "Adjusting an absolute encoder (Page 128)" for
details.
You can select one of these referencing modes by setting the parameter p29240:
Parameter
Note
Referencing mode for absolute encoder
If an absolute encoder is connected, the three referencing modes are available. You can
select the different referencing modes with parameter p29240. When p29240 = 1 or 2, the
referencing process can only be implemented before you use the "ABS" function. Once the
"ABS" function is implemented, the two referencing modes are not available any more.
