My customer has a problem with the Geobrick LV set-up program, running on Windows7 and PEWINpro version is 4.2.11 When setting up a motor, the first two steps complete ok. Upon the start of the third step, the set-up application crashes with a critical error. We did reduce the notation level to none and have admin rights for the user. Any suggestions? On my own laptop, the same application does not crash with exact the same parameters and same controller. Same OS and same PEwin version. There however, I do not see any graphs during step 3 and 4 of the motor set-up. The pmac plot software does not work well with the windows themes for Windows 7 (black fields when setting custom fields), I had to set personal preferences to Windows Basic to get a proper view.

[quote='Sina' pid='1140' dateline='1295542051'] Question: What is the change on Ix25? On a different note, why do you need to change the encoders at all? It seems you're final homing is based upon limit switches and not the index of the primary encoder. Regards, [/quote] Sina, I want to use the secondary encoder as the position feedback and the primary as the velocity feedback. So I do not need to change encoders at all. However, I do want to capture both index markers. The index marker of the primary encoder for the setphase, the index marker of the secondary encoder for the position zero. Can I do this without switching Ix25? Ernst

Ix25 is initially $3440, then changed to $3444. Ix42 and Ix43 are both $3440. $3440 is the primary encoder, $3444 the secondary encoder. Amplifier & limit flags are on the primary encoder. I use the index of the primary encoder to do the setphase. I use the index of the secondary encoder for the position referencing. The limit is only to used to approach the index from one side. The secondary encoder has no fixed relation to the commutation.

I see a different behavior between plc and terminal: command "#9j/" gives a fatal following error when run from the plc (even if given repeatedly or with time delays) and works without problem when given from the terminal. My axis is a rotary motor with hall and encoder feedback, I have a secondary encoder (linear feedback). Both encoders and motor/hall are connected to a GeoMacro drive controller via Macro from a GeoBrickLV. Vertical application. This problem happens during initialization: At start-up, position and velocity feedback are from primary encoder. First do "$" with hall sensor, turn off brake, then "hm" to primary encoder index. Run axis into limit and reverse out of limit. Next apply brake, disable and change position feedback to linear encoder: Ixx03, Ixx08, Ixx23 and Ixx25 to the proper values. Velocity feedback remains from rotary encoder. Then enable again: this is what works when done through terminal and always gives a fatal position error when done in the plc, even waiting 5 sec does not help. After it faults in the plc, I can enable from the terminal without a problem. Open loop runs fine with both feedback options, same current amount needed to lift. It seems that the error is caused by the fact that the feedback channel is changed. Is there any command I can give to prevent this error from occurring?
