Layout and Interface Guidelines

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 earth. 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 MDrivePlus need to be twisted. If more than one driver is to be connected to the same power supply, run separate power and ground leads from the supply to each driver.

Rules of Wiring

•Power Supply and Motor wiring should be shielded twisted pairs, and run separately from signal- carrying wires.

•A minimum of one twist per inch is recommended.

•Motor wiring should be shielded twisted pairs using 20 gauge, or for distances of more than 5 feet, 18 gauge or better.

•Power ground return should be as short as possible to established ground.

•Power supply wiring should be shielded twisted pairs of 18 gauge for less than 4 amps DC and 16 gauge for more than 4 amps DC.

Rules of Shielding

•The shield must be tied to zero-signal reference potential. It is necessary that the signal be earthed or grounded, for the shield to become earthed or grounded. Earthing or grounding the shield is not effective if the signal is not earthed or grounded.

•Do not assume that Earth ground is a true Earth ground. Depending on the distance from the main power cabinet, it may be necessary to sink a ground rod at the critical location.

•The shield must be connected so that shield currents drain to signal-earth connections.

•The number of separate shields required in a system is equal to the number of independent signals being processed plus one for each power entrance.

•The shield should be tied to a single point to prevent ground loops.

•A second shield can be used over the primary shield; however, the second shield is tied to ground

at both ends.
