can anyone talk me through measureing the wave forms of the drive transistors in spindle drives?
my drive is a06b-6059-h003 with a a16b-1100-0200 top board.
I don't know if the S5 jumper is applicable to my board.
the next problem is i'm unsure of where to probe. is it b1-U0 with the oscilloscope probe on B1 and the earth on U0?
I can't see wave forms but i'm probably not testing correctly.
