I 've been trying just about every example I can find but I can't move my stepper motor. Hardware: DirectLogic 06 PLC Stepper Driver Stepper Power Supply Stepper Motor The test feature on the driver moves the stepper back and forth so I believe that is connected correctly. Am I missing some other piece of hardware? Do you need an H0-CTRIO2 to send the proper pulses to the driver? Bubba

What model of DL06 do you have? I believe the transistor (DC) output models do have a high speed output that, while less capable than a CTRIO, could well do basic stepper driving.
However, the relay and AC output models do not, and you would have to have a CTRIO to drive a stepper.

We need a lot more information.
1) What model of DL06?
2) How do you have it wired and what are your part numbers for the controller?
3) What mode are you using?
4) What is your ladder code?

The models of hardware are:
D0-06DD1-D
STP-PWR-4805
STP-DRV-6575
As far as code goes I'm using the automatic trapezoid example from the manual. I 'very added a couple lines of code to toggle the Yankees output on and off. Y0 is wired to step+ and Y1 is wired to dir+.

Sorry it took so long to get the code posted. Didn't have easy access to the system with the code on it.

Please show exactly how you have wired from the DL06 to the STP-DRV-6575
Since you have a 'sinking ' output DL06 you will need to follow the upper of the two diagrams on page 2-7 of the Surestep manual.
Connect the same plus voltage which you wired to the DL06 +V terminal (upper terminal block, far right terminal) to the step+ and dir+ terminals of the drive.
Connect Y0 to step- and Y1 to dir-
And you left out
LDA O3630
OUT V7630
from the first rung. This establishes where the Profile table is located.

The example code I used said those two items were optional.

Then make sure that the value 3630 octal (or 798 hex, or 1944 decimal) is in location V7630 by whatever means.

I 've tried the various items you suggested but still no luck. I'm new at using PLCs and this is the first one with a stepper motor. I probed the signals going from the PLC to the driver and I can see the trigger (Y0) toggling on and off.
Any more tips would be appreciated.
