Roboclaw 2x30a only gives motor one speed

Help & Support Robot Parts

Hi everyone,

I have a trolling motor (Rhino Cobold V24) that I’ve hooked up to the Roboclaw 2x30a controller. I’m controlling the motor with a TBS Tango and X8R receiver. I’ve changed the settings in the Roboclaw software to the RC Control mode but when I push the throttle, the trolling motor only has one forward and one backward speed that consumes around 2amps. Any ideas on why it isn’t generating variable PWM signals to give the motor a variable speed? Do you think it’s the controller or the type of brushed motor?

Thanks for your help!

Keep in mind that the Motor controller is the Roboclaw and not the X8R Receiver.
Try testing the Roboclaw with a 0-5V to see if you can vary the speed of the motor.

This way, you will be able to isolate the issue, it could be the motor controller but also the Receiver.

Normally the Roboclaw should provide variable PWM when connected to a variable RC input like the throttle.

  1. Somehow the signal which the receiver is getting is not variable (i.e. check the transmitter)
  2. There are additional electronics within the motor which might be affecting the signal
  3. There’s another configuration within the RoboClaw which is affecting the signal.
  4. Important to note that the RoboClaw has an onboard BEC, so don’t supply separate power to the receiver

Can you provide a few clear photos of the setup? All documentation can be found under Useful Links here:
