The TMCM-090 module has input pins for the +5V and +48V power supplies. Is there a sequence at which both power supplies should be connected to the board (5V before 48V or vice versa)?
I'm asking this because I somehow killed the processor of a TMCM090, and I am trying to figure out what I've done wrong.
Or maybe, is it wrong to generate the output signal without using the piezo motor as a load? I've connected the 4 phases only to an oscilloscope to see the shape of the output.
Thanks in advance,
