L a y o u t a n d I n t e r f a c e G u i d e l i n e s

Logic level cables must not run parallel to power cables. Power cables will

introduce noise into the logic level cables and make your system unreliable.

Logic level cables must be shielded to reduce the chance of EMI induced noise.

The shield needs to be grounded at the signal source to AC ground. The other

end of the shield must not be tied to anything, but allowed to float. This

allows the shield to act as a drain.

Power supply leads to the driver need to be twisted. If more than one MDrive

is to be connected to the same power supply, run separate power and ground

leads from the supply to each MDrive.
