Speed Controller Control
Hi,
I have some Victor 883 speed controllers from the FIRST competition last year
that I'm attempting to control with a BS2. It has two inputs for +12 and -12,
two for the motor power (the output) M+ and M-, and then a three wire (red,
black, and white) control, as on a servo. I cannot figure out how to control the
actual bi-directional current output of this speed controller, though. I can
achieve forward control by:
loop:
pulse 12,845
pause 100
goto loop
where 845 is slow and 1245 would be very fast.
However, I cannot find a backwards direction that works. The led turns red
indicating a reversed direction but the motor isn't powered. I looked into the
pwm command but nothing came of this, possible since I used it incorrectly. Any
ideas?
