i950 TA Cia402-Advanced: When switching to subindex :085 = 'permanently set' a wrong actual position is displayed, due to a wrongly not reset internal offset (corrected from V03.26.00)
Corrected from:
Library: L_MC1P_MotionControlBasic (FAST Motion) from V03.26.00
(Update via Package Manager)
Response of the new version:
Referencing via the PLC application can now be executed correctly and the internally noted reference offset is set correctly if the following sequence is observed:
First deactivate the option "Homepos available for absolute encoder" in the drive (0x500E:085 = [0]),
then carry out the referencing via the PLC application in the control,
then activate the option "Homepos available for absolute encoder" in the drive (0x500E:085 = 'permanently set' [1]).
In the event of incorrect sequence, if referencing is carried out via the application while "Homepos available for absolute encoder" is activated (0x500E:085 = 'permanently set' [1]), this will now be rejected with an error message.
What happens?
In the control, an incorrect actual position is displayed when switching parameter 0x500E:085 = 'permanently set' [1]).
The reason for this is that the existing offset shift caused by the referencing process previously carried out via the control is incorrectly not reset.
When does the behaviour occur?
i950 with TA CiA402-Advanced with position control and
i950 axis referenced via the PLC application in the controller and then
then activating the option "Homepos available for absolute encoder" (0x500E:085 = 'permanently set' [1]).
