Agreed, I did confuse that portion. So, let's backup. What rating do I use to fuse the above limit switch? Do I use the PLC input's max current rating (12 mA)?

All of my I/O total is 5 amps, I was just saying a good chunk of that is from the limit switch (2.8 A). It appears I may have been misinterpreting the rating (see above).

Perhaps that is what I misinterpreted. The switch spec sheet says 2.8 A @ 24 VDC.

Sizing a Power Supply

I have 120 VAC feeding a Micrologix PLC. I am feeding my I/O with 24 VDC using a power supply. If I add up the current draw of all I/O, I get 5 Amps (largest draw from a limit switch). Does my...

One more....I see you moved a -1 to the P3-08 parameter. Looking at the manual for p3-08, looks like a 1 is used for Modbus, or 0 for external. Where is the -1 coming from? Just trying to...

Really appreciate the help.

For the MSG reads.... is there a need to compare the value to the sent value? Or, will this just flag the ER if it is unable to read the register?

I see how you triggered the msgs now. The MG EN XIO bit turns the OTL on, and the MG DN bit Unlatches.

The advantage to doing it that way is so it's not repeating every X s like in a timer right?

Perhaps I had the 2 mixed up. I will re-read. I thought in absolute mode, I would need to return to home position every time. That will work, just a less efficient cycle.

Thanks, I will review this!

The reading sounds like something I need to add. This will be what I use to verify the motor is at Position 1 before beginning Position 2 correct?

Thanks Steve I will do that.

Sounds like Modbus communication is the way to go between the drive and PLC. Next I will need to see how to set up the ML1200 for that since there is only 1 comm port.

I will look into this more. I like the idea of using more of the servo drives features, and then using a simpler LL program to control.
