    I reckon I was a little late getting my reply

    The motor will only step once for each pulse the PLC sends out, you will need to send a whole series of pulses to make it rotate.

    5v power supply to v+ negative to c0. negative also to my pulse negative and direction negative.
    On the output side:
    You need a wire from C0 to the negative of the PLC 24v power supply, you also need another wire from C0 to the negative of the 5v stepper power supply.
    You need a wire from the PLC +V terminal to the positive of the PLC 24v power supply.
    You then need a wire from Y0 to pulse negative on the drive, as well as from Y1 to direction negative on the drive.
    You then need to take both drive positive inputs and tie them to your positive 5 volt power supply.

    Hope this helps.

    Ok i found out i needed to sink not source. Changed it now I get a signal but just for a single step then it stops. I can hold motor shaft and feel the signal step but no more. it will do it as many times as i trigger the x1 switch.

    Any help is greatly appreciated.

    thanks

    Please post how you wired it. A diagram if you can, otherwise a detailed description of how it is wired.

    Ok i have my plc programmed and wired up for a desktop test. Imputs and outputs lights trigger but im getting no signal to the stepper drive. Any ideas of what I maybe missing?

    Velocity might be better for a continuous move. You will probably need to experiment a bit until you find what works best for your application.

    Thanks. Thats getting me off to a start. But seeing that I need it to only move as long as Im holding the switch, wouldn't i need to use the Velocity Profile? Also I wont need a homing switch due to manual movement by a contact switch. What would be the best way to adapt the example do you think?

    Thanks

    Appendix E of the DL06 User Manual has a sample program under the Mode 30 section.

    Try example 3 on page 53.

    D0-06 dd1 with stepper drive/motor controled by plc

    Im new to plc. Although i have good knowledge with cnc machines and their programming Im having trouble setting up a plc to run a standalone stepper with two limits and to switches for left right movement.

    Basically I want to be able to push or turn a switch and as long as i hold it it will move right until I hit a limit. Then I want to be able to push another switch and it will move left until I hit a limit as long as the switch is activated.

    I know I have to be in mode 30 for this. But I have read and read and cant figure out how to get into mode 30, as well as program the plc to preform the function above.

    Any help will be greatly appreciated.

    Thanks!
Working...
