Denford VMC1300 - Rescued

[m_c]

Your right the RMHV and DDCSV are more or less the same.

I'll use a pot connected to the sprint board for speed control for now.

After a bit of digging on the internet and head scratching I *think* I've figured out why the speed control was set for 50v. I think that the 50v is the voltage from the tacho at max speed rather than the max output.

But worried about your comment regarding the motor failing taking out the speed controller, what tests can I do on the motor to establish if its good or not?

Have a read of the manual for setting the pots. Plus I think there may be posts over on the Denford forum somewhere where the Denford guys give a few pointers for setting the drive.

Generally carbon dust builds up, causing ground leakage, and/or shorting between windings. However the motors are not the easiest of things to dismantle to clean properly. I damaged the tacho trying to get mine apart, but then I was more interested to see what was in it, as it was already destined for the skip as I upgraded to a servo spindle.
