Hello!
In the upcoming weeks I am going to order a Keling controller kit and I have a few questions for the masses.
This kit is going to be for a Standard Modern 13 X 34 lathe.
My questions are simple and probaly VERY common. I see the controller board is good for 2 or 3 axis machines..but the power supply is "only" a
48V/12.5A
controller info at top of page -
http://kelinginc.net/ControlSystem.html
So, someone correct me if I am wrong - but on Kelings site at the top of this link (
http://kelinginc.net/SMotorstock.html )it says "The Max. applied Voltage can be up to 20-25 times of Rated Voltage *** "... and the amperage can be 2/3 of the combined amperage from the motors that are bieng used...Right?
So, given this, 2 or 3 steppers @ 2.1V can safely run off of this power supply?
I am talking about the NEMA 34 HIGH TORQUE STEPPER MOTOR 906 oz-in, ½” shaft with a flat, 95 mm
KL34H295-43-8B(Rated Current: 6.1A, Rated Voltage: 2.1V (in Bipolar Parallel)
I'd be the first to admit I am electronically challenged, so I am looking here for help.
Now, that hurdle is over with - I didn't see anywhere that said what RPM these motors turn at the given voltage. I need this info to determine what these motors will need, as far as pulleys and ballscrews are concerned, to keep them in peak operating range given the rapids I'd like to see (~300 IPM)...
Last but not least, since I am electronically challenged and don't know squat about wiring I was wondering if the controllers can be "upgraded".. I.e. add a C3 pulse card if it doesn't come with one, prewired for coolant pump control, and possibly prewired for a VFD..
..or is the last part even that difficult?
Thanks for the help guys!
