Hello,
I have an old Motion Science, Inc. Stepper Drive. It is PN MSFX16006-01, Manufactured in 1991. It has failed, will not move the motor properly. I can purchase a refurbished one, but since I have a bit of time prior to needing it, I would like to attempt a replacement. I have contacted all companies that provide repair services, as well as the company who sells refurbished ones. They have been as unhelpful as possible. It seems that obtaining a datasheet or wiring diagram for this part is impossible. If you were me, and didn't want to purchase a refurbished one just yet, how would you proceed with determining the functionality of a non-working device to the point where a replacement could be specified.
Things I will need:
1. Microstep Resolution: (this is dip switch selectable, but I don't know what the dip switch settings actually mean in terms of steps / rev
2. Bus Voltage: I can measure this.
3. Motor Hookup: There are 4 wires to the stepper, labeled S and C. I believe these to be for SINE and COSINE.
4. There is a DB15 Connector which gets 10 signals (some are probably power / common / gnd) This is the biggest roadblock, and where I'm seeking advice.
I have most basic electronics tools available, voltmeters, oscilloscope, logic analyzer, etc.
Thanks for looking!
