FRAGE:
How to configurate an axis without encoder in the standard application?

ANTWORT:

Beispiel: Zwei Gantry-Achsen haben keine Geber.

1. To delete TO_Gantry_1 and TO_Gantry_2, configurate two TOs with exact the same name, but without check off 'positioning', refer to Manual 10/2010, Chapter 8.13.2.2.
2. The position-coupling between Gantry 1 und Gantry 2 must be removed:
   • go to program/Gantp_2/gantrymcc_2_s/Operation Mode
   • open Crane_FB_Library.fb_op, you find "to_checkbackmasteraxis" at the line 83 (V2.0 SP1) or the line 82 (V2.0 SP2)
   • delete the content "Gantry_1"
3. To delete the function 'Referencing' for Gantry
   • go to program /Mon_Ref/referencingmcc_1/
   • delete the Modul 'Gantry'
4. To set one signal manually to 'True' by doing (Only for V/f control*):
   • go to program/Gantp_1/gantrymcc_1_s/Operation Mode
   • open the program Crane_FB_Library.fb_op, you find "bocheckbackSpeedControllerActive' at line 80 (V2.0 SP1) or at line 79 (V2.0 SP2)
   • setting it as 'TRUE'
   • repeat it to TO_Gantry_2

Reason (Manual 10/2010, P.211, Note):
In the V/f-control the speed controller is not used, as a result the 'speed controller active' signal is not automatically set.

Note:
For configuration of all Gantry DOs it is always required to select the control-mode 'n/M control + V/f control, I/f control', otherwise the drive can’t be controlled by Simotion. It is also possible to select 'V/f control' by Sinamics parameter p1300 later on.

* The 4th step must be only applied, if you use V/f control. If you use sensorless VectorControl [Speed control (sensorless)], then don't change anything, except to configurate the DO without encoder.
