    Hi JHL Yes - post the CX-P and NQ-D projects. We can establish comms between these first. We can move onto temperature control later... It's a CP1LM40 you have there. I wanted to know to confirm that channel 2 is correct (it is) Cheers, Pp

    Hello Which model CP1L are you using? Are there any other expansion units? Is there any data in the address '2'? (the temperature) Do you have communication between the NQ3 and the CP1L? If you post your projects, we can have a look... Pp

    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

    Hello 1. Have you made a STARTUP program; this will create an image of the existing VR memory on power up? 2. Is the controller RUNning? Find which program starts the others, and RUN "program name",1. You may need to find which program (task) runs on power up from the working contoller.

    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

    Hello AC DC I hate to see a thread with no replies, so here's an idea... I've never done this, but the files on the CF card can be accessed via FTP. Would it be possible to invoke an FTP client from within CX-S and get to the files this way? I don't think FTP functionality is built-in to CX-S, so embedding a third-party piece of software may work? I'd be interested to hear any results! Pp

    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

    Hi Jay You guys use the MX2 and CX-Drive don't you? We've had this for about 6 months or so. You can perform PLC-type logic within the drive itself. Quick run down: 1. Access to all 7 inputs, 3 outs, both analog ins and analog out. 2. 5 tasks (multitasking). 3. BASIC-type language, entered as flow chart. 4. Read/write access to 'everything' the inverter knows. You can programatically turn 'on' anything you can normally attach to an input. 5. Very handy!

    Hello Just interested to see if many of us are using the Drive Programming functionality yet? I've done a few jobs with it up to now. Works well in conjunction with the 'Simple Positoning' too. Pp

    First thing to note is the RJ45 connector isn't ethernet. Use the mini USB connector instead. It's a lot easier to set these things up via CX-Drive rather than the keypad. You could define a fixed speed of 60Hz, and select this via a digital input and have F001 vary the speed otherwise.

    Hello What you describe is what I would expect. Are you editting the speed from the keypad? If so, this edits F001 (IIRC), and the inverter won't know any different when it starts again. If you want it to always start at 60Hz, I'd use the excellent drive programming functionality. Pp

    Hi Sylvester This should be easier than it is! I've used a couple of methods: 1. Make the data record title one of the actual data record entries. Attach it to an internal address ($W___) and you can display it this way. 2. There's a function that can be attached to a 'Command' button, which is 'Read record label'. There's some flexibility in its arguments to select which record to read. HTH Pp

    Hi SW I think the OP meant Reset, not Preset the integral. I've had a look, and can't find anything, I'm afraid. I guess one of the 30 or so Words the PID intruction uses is the integral portion of the output. I'll try to decode it next time I'm using it... Edit: Not sure here, but can you change the integral gain to 9999 (disabled); I don't know if the integral action will return to what it was or start at zero again when you re-instate the 'correct' I gain?
