2.2.2. IO and Signal Wiring Requirements

The I/O, communication, and encoder feedback connections are typically very low power connections. In
some applications, especially when there are significant wire distances, a larger wire size may be required to
reduce the voltage drop that occurs along the wire. This increase may be necessary in order to keep the
voltage within a specified range at a remote point.
Low voltage and high voltage wires should be kept physically separated so that they cannot contact one
another. This reduces the risk of electric shock and improves system performance.

Signal Wiring
Low Voltage Power
1. ≥ 30 V if the wiring is not in close proximity to wiring operating at voltages above 60 V.
2. Insulation rating will need to be rated for the higher voltage if the wiring is in proximity to wiring operating at voltages above 60 V.
3. Larger gauge wire may be required to minimize voltage drop due to voltage (IR) loss in the cable.
