Greetings from the dry Northwest.
I am starting my 2nd quarter project. It is to use VFD and PLC to control imaginary automated drill to drill holes in a circular part say a flange with six bolt holes. Machine will
1. index the part
2. then drill hole
3. rotate part to next position
4. drill next hole.
Because we cannot purchase we are restricted to scrounging, cannibalize, borrowing, begging, etc. We have complete setups for hydraulic component learning (pumps, valves, servo valves etc etc).
SO the drive motors for the drill and for the index table are hydrulic. Each drive motor setup has a tach gen and a potentiometer for position sensing. Drive speed is appprox 2 to 300 RPM. Tach gen is 7Volt per 1000 RPM.
VFD will control pump speed, PLC AB 5/05 will control drill speed via the pump speed using the VFD. I think we are going to be OK on pump speed to control drill speed.
The snag is on the part rotation. We intend to use a stepper to rotate the part.
We have
1. a stepper motor but I did not bring home the data on it.
2. AB 1746 HSTP1 stepper controller module (this is never used still sealed). AB manual says we need a stepper translater.
3. Instructor dug out a
Warner Electric Slo Syn model number SS 2000 MD 7
RATINGS 24 to 75 VDC 4 amps.
I looked at factory web page to see if compatible with AB controller no mention.
E mailed local rep and factory -- awaiting response.
AT LAST -- The question
1. Will the Slo Syn be compatible with the AB stepper control module.
2. Have any of you used this combination?
3. What success (or lack of) did you have???
Thanks for the help
