I need some help please. I am trying to use a FP Command in the Sure Step software with the Click plc. To control a stepper motor. I would like the stepper motor to start at one FP command Location then with each additional FP Command turn backwards. But I am missing something the program I wrote does not work. I thought I read that if you give a FP Command lets say of 80,000 steps and another of 40,000 steps the motor would turn backwards. I tried to follow the example from the website but it is not working. Any and suggestions would be greatly appreciated. Attached is my effort so far This is my first time trying to do a motion control

    You would probably get faster help from the Technical Support group.

    But, just reading the manual (I haven't used this) have you tried using separate 'dI ' commands which set the target followed by 'FP ' commands with no parameters?

    Can you get the desired results from the stepper when running the exact same commands using the SCL terminal software on your PC?

    Also, are you able to make the stepper do anything using the CLICK?

    Thanks ' bcarlton

    No I have not tried the DI Command. I will look into that and tech support.

    I have learned a lot from this form from some smart people so I did not even think about tech support.

    I can get the stepper to move but it doesn't seem to do what I think it should do. I have the following

    Click plc

    stp drive 80100

    motor 34079

    power supply 4810

    From what I understand in the directions using a FP Command with reducing number values should rotate the motor less revolutions with each reduced value FP Command

    Inside the SureStep Pro software that you use to configure your drive, you can go to Drive>>SCL Terminal, and from there you can run the commands to find out what it *takes to* make the motor do what you want. After you can make it do what you want from there, then you can translate it over to your CLICK program. This will help to see which problems are in the CLICK program, and which problems are in the commands.
