A2M-80SV02430 servo and S2-SVD15 driver

Recently picked up this servo and driver off Amazon because it was suspiciously cheap at $106 for the set.

Sounds too good to be true but oddly enough it arrived and works.

Here's some notes:

• Running at 110V unloaded it's able to get up to about 3.5-3.6kRPM.
• Running at 110V I was able to confirm, with my limited instruments, that it could produce ~6Nm peak torque. It may, with better testing and its full voltage, be able to reach its advertised peak torque of 7.2Nm.
• There is no serial port, even if the manual/product page says there is. Not sure if the firmware would support it if you populate the empty headers.
• It appears to use a single-turn absolute position encoder. Likely it communicates with the driver via some sort of serial method instead of the usual quadrature.
• The encoder/position data is not available as an output on the parallel port.
• The parellel port IO is rated for 12-24v. However, using 5v for the enable signal appears to work fine. Wired for single-ended quadrature inputs, I found I needed about 11.6v for it to work reliably. If I configured it with a fake differential signal (VCC and ground are different, right?) it seems to work fine at 5v.
• Opening it up, it appears to have an internal brake resistor.
• Not sure if there's any real difference between the A2M-80SV02430 servo and a regular 80ST-M02430 servo beyond the encoder.
• It was cheaper with the holding brake, so my servo has a "Z" at the end of the model number. Pump ~24v into the holding brake connection to release the holding brake. (Background: The holding brake helps keep the servo from turning when it's unpowered/e-stopped. The servo is actually strong enough to overcome it. The holding brake is different from the brake resistor which is used to throw away power when the servo is electrically decelerating.)
• To get wires into the black terminal thing, jam a screwdriver into the *side* and insert the wire into the round hole. I think you're supposed to be able to put a screwdriver in the top rectangular slots, but I wasn't able to get it to release that way.
• All the parameter numbers I've looked at in the manual match up with AASD-15A parameters so far.

@Thanos @RaaR: Hopefully that helps provide some more data to this conversation.

@Thanos: Do you see any reason it wouldn't work with your controller? Is it an issue if the servo driver doesn't send live position feedback? Namely, does sensorless homing (hard stop torque limit) still work?
