I am using an AB L27ERM PLC and a Kinetix 350 Servo, now I have almost zero experience with servos with the exception that I have been reading through the programming/set up manuals for this servo. As such I have established communications with the servo and even completed the hook up tests for Motor and Feedback with zero errors.
So I'm hoping that my question(s) will give me that additional info that I seem to be lacking after they are answered. I have a sensor wired in to pin 26 & 30 and I want to use that as my home position. Additionally I want my home position to be zero. While watching the data tag for Actual Position, when I move the servo by hand the positional data changes. One of my questions is how do I set a value of zero for this home position?
Now the fun stuff!!! I've read about the Motion Direct Commands, but I'm not really getting how they work or how to use them in a PLC program. The basic scope of my project will be starting from a zero reference position (home) move forward to whatever position I specify. This will actually be controlled by a touch probe, so we will move forward until the touch probe is made. Then I will capture that positional data for other uses, but after making contact on the part with the touch probe. Once that happens then I will want to reverse direction and go back to the home position (zero position).
So I need help with:
1. Establishing a zero reference position as my home position with the wired sensor.
2. Motion instructions, which ones to use for forward, stop, reverse.
I think that's everything.....for now!!!
