I have spent some time in a lab playing around with a ControlLogix, which had a SERCOS card running to an Ultra3000 which controlled an AB servo.
It was a very nice setup and I didn't have much trouble programming the servo to do some pretty cool things.
Are those four components always required when dealing with servos?
PLC -> Motion controller card -> Drive -> Servo
If you had an SLC 500, would you need a SERCOS card for it? I ask because I haven't seen any SERCOS cards for the SLC 500.
Assuming that a motion controller card is required in the PLC rack, are there cards like this for SLC 500's?
Or can you just go direct from the PLC to the drive? ie:
PLC -> Drive -> Servo
I am looking at just using two small servos to control a couple of small tables which must be able to be positioned very precisely, but they don't have to get there very fast.
Another question: Is a high speed counter card used for motors which have encoders, but which are not servos?
