Victor 888 PWM Problems

Hello everyone!

I am here on behalf of FRC Team 5196, Breaking Bot, and we're experiencing some problems. After the second our kits arrived where we were hosting kickoff, we began to build the kit bot and finished it with in a few hours, as well as all of the programming aspects such as flashing the cRIO and the wireless bridge. When we finally set the robot on the ground to test it with a joystick, the Victor 888 motor controllers would not stop flashing amber/orange, which (according to the manual) indicates that they are receiving no PWM signal.

We disconnected one of them from the motor and hooked it's power and PWM cables to our only Jaguar motor controller and it worked completely fine. We then took the Victor 888 inside and tested it's PWM with an Arduino and oscilloscope and it was still creating the same problems.

Is anyone else experiencing these problems with the new Victor motor controllers, or does anyone know how we can troubleshoot the problem?

Thanks!
