Hey all, I'm trying to build a winch for the 14' projection screen that
going up over the ballroom stage out of a wheelchair motor assembly. Per
Jake's suggestion, I hacked 2 server PSUs to get 24v@14a but the controller
is not working and the error code says the right wheel/motor is missing/not
engaged. Anyone know what I am missing? Do I need to jump something to get
the controller to engage while it is "incomplete"?
Thank you,
robb

wow, you have done well.
the answer is that it detects the missing wheel because it can't see its
BRAKE electromagnet.
the solution is to connect a resistor to the place where the other
motors' brake coil would connect. it should be a resistor of a similar
value to the brake coil on the motor you do have, or maybe more ohms so it
uses less power when it gets energized.
a lightbulb might work, but it will see 24VDC when energized, so it would
need to be a 24v bulb or two identical 24v bulbs in series.
as for the anderson connectors on the motor controller, please don't cut
them or mess them up - if you need to connect to them (for example to
connect to the brake contacts for the missing motor) there should be other
anderson terminals in the basket where the motor was. Thanks for not
hacking up the wires on the motors controller.
and congratulations, you're close! once it works, we can use the other
electronics (this is from an old robot) to automate the process of sending
the screen up and down.

found teh info on motor http://www.cncwright.com/E690.html (looks like it
might be 120vac motor w/24vdc safety brake)
but nothing on the solenoid resistance - left a msg w/electrocraft support.
as for the bulbs in series, i assume you meant "two identical *12*v bulbs
in series" otherwise i'm confused.
can't help wondering if bypassing the controller & driving with 120ac/24dc
might be better/slimmer especially if building more for motorized lighting
trusses.
ty for teh info

for the brake resistance - MEASURE it with a mutimeter :)
and yes you're right, i meant to say two 12v bulbs in series.
