Dual throttle control on the SMC 24V23A

Is it possible to configure the Simple Motor Controller to accept separate analog inputs for forward or reverse directions, alternatively using one of the inputs to control the direction?

Hello, zyanide.

Using the input scaling settings, you could configure your analog inputs so that their scaled value is always positive, then use the “Right” mixing mode so that the motor speed is computed by taking the scaled value of channel 1 minus the scaled value of channel 2. This means that when channel 2’s scaled value is 0, channel 1 would control the speed of the motor and the motor would only drive forward. When channel 1’s scaled value is 0, channel 2 would control the speed of the motor and it would only drive backwards. Is this what you want?

I’m not sure understand what you are trying to do, but the documentation of how the analog inputs can be configured is here:
pololu.com/docs/0J44/5.1

If you have a microcontroller connected to the Simple Motor Controller and you are controlling it with serial commands, you can read the two analog inputs from the Simple Motor Controller and use them in any way you want to calculate the speed and direction of the motor.

Maybe it would help if you told us the bigger picture of what you are trying to accomplish.
