Re: Victor and Spike in same circuit?

Looking to operate it as follows

1. Raise Arm. (Victor controlling speed, spike controlling nothing really passing voltage through)
2. Arm Stopped. (Victor to neutral, spike to brake (rev & fwd = 1))
3. Lower Arm (sam as raise just other direction)

Is this legal?
Would it work?
Any other options we might try?

Thanks in advance,

Phil
Is setting the Victor's jumper to "Brake Mode" (Jumper pins A and B right on the Victor) not providing enough backdrive resistance?

In our team's experience, setting the Victors to Brake Mode behaves very simliar to shorting the motor leads in neutral, and it's all done automatically for you.

If it doesn't provide enough backdrive resistance, you may need a mechanical solution as running your motors at stall to keep it stationary isn't a viable option.
