Mr.lemonnier Posted March 4, 2011 Report Posted March 4, 2011 I'd like to know if any of you already used the positioning option of the Omron 3G3MX2 drive ? What I wanna do is connect my encoder directly to the drive and set the 8 position of my receiver boxes. The drive will need to position the rotative table directly in front of the box, stop until the ejection is complete and replace itself to home position. I think it's possible but i've got some issu with the programmation. Any help will be welcome ! Mick
ParaffinPower Posted March 5, 2011 Report Posted March 5, 2011 Hello Mick I've used this a few times, and it's pretty good. Attached is a CX-Drive project which shows which parameters you need to adjust. I think P075 sets the inverter for a rotating co-ordinate system, ie. it will take the shortest route. Make sure the motor is auto-tuned first, as good low-speed operation is critical for accurate positioning. Also, the EA (Phase A of the encoder) terminal input is 32KHz, so choose your encoder symathetic to this! EB (terminal 7) is rated MUCH lower but isn't a problem as the drive 'knows' which direction it's going. Come back with any questions. Pp PositionDemo.zip
Mr.lemonnier Posted March 7, 2011 Author Report Posted March 7, 2011 Yeah ! this should help a lot, thanks buddy !
Mr.lemonnier Posted March 16, 2011 Author Report Posted March 16, 2011 I could not find the auto-tune function. Could you point it out to me please ?
ParaffinPower Posted March 16, 2011 Report Posted March 16, 2011 Hi Posted the user manual here . Search 'autotuning' and the first reference is a step-by-step guide. Better results if you use 'rotational' autotune, and the load disconnected IMO. Pp
Mr.lemonnier Posted March 17, 2011 Author Report Posted March 17, 2011 Ok I've follow the step-by-step guide but can't get the auto-tuning to work.
ParaffinPower Posted March 18, 2011 Report Posted March 18, 2011 Salut Do you get the 'failed' symbol on the display? Pp
Mr.lemonnier Posted March 18, 2011 Author Report Posted March 18, 2011 (edited) Yes I got this message, and I've follow the step, set the parameter H020 to H024 and tried the recommandation in the manual. Also i've been unable to open the file you send me with cx-one. Edited March 19, 2011 by Mr.lemonnier
ParaffinPower Posted March 19, 2011 Report Posted March 19, 2011 Send your CX-Drive file, and motor nameplate details so I can look. Pp
Mr.lemonnier Posted March 21, 2011 Author Report Posted March 21, 2011 I think it will be OK, I've got the simple positionning working good !! Thanks for all the help buddy !!
Mr.lemonnier Posted March 24, 2011 Author Report Posted March 24, 2011 (edited) Ok I'm still having issues with my programmation. I've got a 1000 PPR Encoder and no information about my engine, the faceplate is missing, but its around 1 Hp 3 Phase 208 V. My problem is : let say I ask for the position 250, it goes there, stop with DC injection and goes back to zero (working just fine). But the second time, It does around 50 pulse, stop, and gave back error : E80.3. I'm sending you my program. Also i'm unable to auto-tune my engine and upgrade Cx-drive to open the file you send me.

ParaffinPower Posted March 28, 2011 Report Posted March 28, 2011 It looks ok. One suggestion may be to move PCLR from Input 7 to input 6. Input 7 is used for phase B of the encoder (when used) I've never used 'without limitation' (P075=1), so maybe change this to 0 to test. Paul
