Hi all.
Question regarding skid steer.
I need to replace my dual motor controllers that are currently setup using 2 servo channels for forward/reverse and steering.
Unfortunately the new dual motor controllers(running 4 X bldc, hall sensored motors) only accept analog voltage signals for throttle(forward) and a reverse switch. This obviously needs 2 separate channels.
I need to use pwm to analog voltage converters. Not sure how to proceed with this!
Has anyone got an idea of how to set this up to work?
These are the pwm to voltage converters recommended by motor driver supplier. Just don’t know how this will work with Servo 1 and 3 for Skid Steer.
you would use it set as a “brushed with relay” that will give you a duty cycle output for the pwm to voltage converter and a relay output for reverse.

Oh really?
Will read through it now! Thanks for that.
I also found an option with the specific Dual motor controller that it accepts forward, reverse without a reverse switch.
If the throttle voltage is 2.4v it will be parked(no movement).
Below 2.4v will reverse and above will go forward.
