Encoder counts wrong after Firmware update to 7.2?

[saimen54]

Hi,
I recently updated the firmware of my motion controller card 7344 PCI to 7.2.
Since then a 360degree-rotation in 15degrees-steps seems to miss one 15degree-step. A 360degree-rotation stopps at 345degrees

I think that maybe the encoder counts wrong or the move function isn't executed one time.
Has anybody expierienced similar problems or has any hints?

Thx.


PS. Does anybody know a way to downgrade the firmware to the version below? It seems that the firmware update causes the problem.

saimen54,

Odd behavior.  Is there anyway you could post the code for a simplified version of your program that exhibits this same issue.  I don't think there will be any other way to troubleshoot your issue without taking a look at the code.
