Stepper motor wiring advice.
« on: 13:52:38, 11 May, 2017 »
I have a McLennan geared stepper motor that I want to use for focusing, taking the output from the MountHub Pro focus controller.

I’m just trying to see if I have the wiring done correctly.

The focuser output is via 5 pins of a 9 pin D connector as follows:

D PIN connector  / Output

Pin  1:   +2
Pin  2:   -2
Pin  3:   +1
Pin  4:   -1
Pin  5:   12v


I have the Stepper Motor wired up this way: ( see pic)


Terminal Block number / Input
4      -1
1      -2
3’4’      12v
1’2’      12v
3      +1
2      +2

Just wondering if this is correct, would appreciate any advice please?  Stepper motor PDF file also attached.

Should be. The easiest way it to check continuity with a multimeter. If it just buzzes when powered up then the Polarity of one coil or the other is reversed.
