Re: A curious situation...
The motors are CIMs - all from previous KOP.
The problem occurs when the pwm cable is moved from one Jag to the other. When plugged into one Jag, the wheel runs forward, plugged into the other, the wheel runs backwards. (In each case, the other motor is back driven during the test.) The code is the same... -Mr. Van |

Re: A curious situation...
even though this should be impossible to mess up since it fries the jags:
are the input voltages to the jag connected in the same way? (+ to +, - to -) if power input to the jags is the same, I would test the same jag with different motors, this would confirm whether the problem is with the motor or the jag. if the same jag induces different directions in different motors, the motors are to blame. if the same motor turns different ways under different jags which have the same input voltage and signal, the jags are to blame. let us know what happens, i'm curious! -Leav |

Re: A curious situation...
For anyone who is interested, it turned out that indeed one of the CIM motors is wired backwards internally. It runs in the opposite direction of all of the other CIMs we have.
Odd. Has this happened to anyone else? -Mr. Van Coach, Robodox |

Re: A curious situation...
We had a backwards CIM in 2010, ended up destroying a toughbox.

Re: A curious situation...
Acidentally programmed my drive code wrong so one CIM was fighting the other. Thankfully nothing was damaged.
