driesterer Posted January 2, 2007 Report Posted January 2, 2007 I am looking for some logic instructions for using a stepper motor with the ic200udd064 ge micro 64. This is new to me. I am not sure which instuctions to use and how to write the code. I just need to run the motor one direction, stop there for a while then return to home. I am using Proficy machine edition with a micro 64 #IC200UDD064-AA(Firmware upgraded to 3.6). Any suggestions?
Steve Bailey Posted January 2, 2007 Report Posted January 2, 2007 Read chapter 12 of GFK-1645; High Speed Counter, PWM, and Pulse Train Operation. You will use a pulse train output. Each pulse commands the stepper to index one step. The pulse train output gives you control over the total number of pulses to output and the rate (pulses per second).
RussB Posted January 2, 2007 Report Posted January 2, 2007 (edited) VM64_Motion.zip With firmware version 3.6 and the latest Proficy ME software you can use the new motion Function blocks for the 64 point VersaMax Micro. 'Find_Home' 'Jogging' 'Go_Home' 'Blending' 'Stop_Motion' Plus increased speeds on the HSC input and PWM Outputs, which includes DINT use. You do need the DC output version for this. Attached is an example of 'Find Home'. I have a preliminary manual if you need more help than the PME online help provides, but it includes most everything the experienced GE Fanuc programmer will need. Edited January 2, 2007 by RussB
driesterer Posted January 2, 2007 Author Report Posted January 2, 2007 I'm not able to open the file. is says "fxCim not configured properly".
RussB Posted January 2, 2007 Report Posted January 2, 2007 (edited) This is a Proficy ME backup file, you "Restore" it from with in PME. I have PME version 5.5 SP2 and SIM8. Edited January 2, 2007 by RussB
driesterer Posted January 2, 2007 Author Report Posted January 2, 2007 Thanks for your help. I was able to get connected but was not able to run my motor. ER turned on. Not sure what the error is. I powered down the PLC then powered back up, but it never came back. The OK light just flashes a few times then goes out then flashes and goes out. Any ideas?
RussB Posted January 2, 2007 Report Posted January 2, 2007 No idea, send this information along with a backup of your logic to support@gefanuc.com and ask them to verify your findings. If they can you may have found a 'bug' if not you may have a bad PLC.
driesterer Posted January 9, 2007 Author Report Posted January 9, 2007 OK, I got a new PLC under warranty. I still am having trouble with the logic. I am using the Homing instruction you provided, yet it seems something is missing. I have output Q5 for direction, but where is the analog step output and The controller I have needs a step input as well as the direction input. It also has an "EN" input.
driesterer Posted January 10, 2007 Author Report Posted January 10, 2007 My programming skills, or lack of, has been limited to discrete I/O. The analog part is throwing me. I have to make a stepper motor turn. I have narrowed the error down to AQ505 not being set to "1". When I set it, it will switch back to "0" on it's own. The other thing I am lost on is which terminal on the PLC does the analog out put come from?
RussB Posted January 10, 2007 Report Posted January 10, 2007 Post a backup of your project here, maybe that will help to describe what you have.
