Hello everybody!
I have a conveyor that is working in the following order:
1. Part loaded onto conveyor
2. Conveyor moves / "steps" forward (moves a fixed distance; motor runs until it receives a signal from a proximity switch which are mounted on a plate that rotates with the conveyor. This plate will give a total of 5 pulses pr. rotation. 1 pulse = 1 step)
3. Conveyor waits a certain time
4. Sequence repeats...
The thing is that I now want to be able to vary the distance the conveyor are moving from the plc. So I was thinking along the lines of using a encoder (absolute, since I'm not able to move to a referance) or using some kind of pulse transmitter. Or maybe it's just as simple as adding more "pins" to the rotating plate so I'll get more pulses pr. revolution. I think this should cover the resolution thats needed.
Does anyone in here have any experince with which solution I should use? Encoder / pulse transmitter?
Thanks in advance!
Cheers
