I have a 12V switching power supply that I have used to bench test three 200F servo drives individually. All three connect properly to vipertune and communicate with the encoders properly.
When I connect all three to the power supply the green led lights up on all three, but there are no flashing lights and I cannot connect to vipertune.
When I connect two of the drives to the power supply, the green led lights up and the red leds flash on both.
I have tried two other lower quality power supplies and one will only properly power a single drive and the other won't power any drives.
This sounds like a power supply problem, Does the viper drive have issues with switching power supplies?
