Sprint 400 driver board

[dazp1976]

Hello

Can someone help me with the wiring of a Sprint 400 driver board. The manual is here

https://www.sprint-electric.com/wp-c...0_1200-web.pdf

I want to connect it to the spindle on my Denford Micromill. The datasheet gives 4 outputs, two as "armature" and two as "field". I have to admit that I don't really know what these mean or how to identify the four on the spindle. However, when I apply mains power to the board, there is 0V on the "armature" pair, and 200V DC on the "field" pair. If I connect the 10V reference on pin 1 to the input on pin 3, nothing changes. What I need is for the DC output to go from 0 to 90V (the spindle maximum). Would appreciate some guidance

Something sounds amiss. Did you blow yours up or was the drive not supplied in the first place???.


I can't see it happoening myself. The 0-90v units look like they run off 115vac input. (u.s. ver input)
On 230vac input they give you 0-180v (looks like this is what you are finding). (u.k. ver input)

PLEASE NOTE:
There is only one board that puts out 0-90v on a 230vac input and that is the:
KBIC-240DS
This is extremely likely the one you need.

Who put you onto the sprint???.
The sprint is for the 180v motor types that exist, or the u.s. 90v types.

The official boards are these by the looks of it:

(sounds like the motor would be the u.s. standard one and they threw a quick fix board in for u.k voltages if you weren't given the control).

There's 3 options here.
1. you find a 180v motor for it.
2. have to resort to the buying the KB control board.
3. get 115Vac input to the sprint 400.
