GSS Posted July 15 Share Posted July 15 Looking for what should be a Global Tag for Bus Status. Geo Brick drive running Pewin32 Pro 2 software Quote Link to comment Share on other sites More sharing options...
steve.milici Posted July 15 Share Posted July 15 I’m not sure what you are requesting. Can you be more specific? In general, the reported errors for the drive are shown on the scrolling single-digit 7-segment display. See the hardware reference manual for your particular drive.

GSS Posted July 15 Author Share Posted July 15 Manual dictates that I must phase motors on power-up before they are able to run. PLC1 ( runs once at power up ) example in manual does not check to see that there is ~120-240 VAC applied so phasing can actually perform. PLC1 runs when 24 VDC is applied but must wait ~3 sec before applying 120-240 vac to powr bus. It appears that PLC1 program runs but fails to phase due to lack of bus power. If I run it again, manually, after bus is up, it works fine. Something not right here ! Quote Link to comment Share on other sites More sharing options...
steve.milici Posted July 15 Share Posted July 15 There is nothing wrong here, phasing will fail if there is no bus voltage. A well written phasing PLC would check for bus voltage not present errors. This is different between the Brick-AC and Brick-LV versions but is fully documented in the “Troubleshooting” chapters of each drive manual.

GSS Posted July 16 Author Share Posted July 16 You say that but the manuals I've been given by the Omron folks are innacurate in many instances. Why do you think I am posting ?? Not trying to be an ass but the sample code's have many syntax error's and in my case, try to phase w/o checking for bus power among other issue's.

steve.milici Posted July 16 Share Posted July 16 I don’t know what “Omron folks” you have been working with but the latest manuals for the Geo Brick LV and the Geo Brick AC are accurate having been proof-read by several groups and the “downloadable” example code checked for syntax errors. I have attached the latest versions to this post. Please let us know what syntax errors you are experiencing. The example code provided in these manuals is not considered “comprehensive” and is expected to be edited to reflect the full application requirements. As for the phasing Power-on PLC you could add the code to check for bus voltage not present or simply place a timeout at the beginning to accommodate the bus power delay. Another technique would be to disable power-on execution and run the PLC “on demand”. Geo Brick LV User.pdf GEO BRICK AC USER.pdf Quote Link to comment Share on other sites More sharing options...
