REV Servo Module

Hello,
We are trying to use the new, legal REV Servo Module with the following servos:
https://hobbyking.com/en_us/robostar...16sec-73g.html

Now, when connected directly to the PWM output on the RoboRIO, they work according to the angles they are set to, but don't have the needed power to perform the way we need it (which is why we need the REV Module).

When connected vie the module, the LEDs mark that everything is fine, but the servo doesn't move at all and doesn't recieve any command. When plugging in a regular HiTec servo instead to the module, it works.

We are not sure what is the reason for that, maybe different PWM frequencies than the servo requires, or maybe some other reason.
Anyone has any experience with the module? Maybe our servo is just unsuitable for the module?

Re: REV Servo Module

I don't have any experience with that servo or the servo power module, but the page for the servo lists "removable input wire lead" as a feature. I'd want to make sure that feature wasn't engaging when you plugged the servo into the Rev module.
