Do you have direction relays/control attached to it?.
Just thinking a 5v+/- swing may happen if no particular direction control specified is seen by the board.

You can use the +/- 'swing' as a cw/ccw control in servos.
Just a thought.


I'd be considering getting one of those cheapo $10 5 axis breakout boards (with the built in 10v output) on another port atm. They do actually work because they're basic.

The C6 board does use relays for direction control. I'm not seeing anywhere in the manual, or from my google-fu that the C6 boad will do -5v to 5v control, or 0-5v control.

The manual has this which is where your problem is it needs the output to the board to be 10v your output is 5v so you only get 50%

A Variable Frequency Drive or Inverter works by modifying the frequency for AC motors.
You can control most of these devices with an external analog signal (0-10VDC). That is,
if there is 5VDC coming into through the control signal, the motor will run at 50% of full
speed, if there was 10VDC, the motor will run at 100% of full speed. If there is no signal
coming out, then the motor will stop.
This unit can also be used on many DC motor controllers by replacing the potentiometer
that controls the speed.
