Drive Electrical Installation Chapter 3
Control Signal Wiring Design
Considerations Use shielded cables for all the analog and digital control cables.
Steel conduit or a cable tray can be used for all PowerFlex 6000 drive power or
control wiring; however, use only steel conduit for all signal wiring.
Wires for digital and analog signals must be routed separately.
Control cables and power cables must be routed separately; the distance between
the control cable tray and the power cable tray must not be less than 300 mm.
If the control cable must pass through the power cable tray, the angle between the
cable trays must be as close to 90° as possible.
Do not mix AC and DC wires in the same cable bundle.
General Wire Categories on page 73 identifies general wire categories for
installing the PowerFlex 6000 drive. Each category has an associated wire group
number that is used to identify the required wire. Application and signal
examples, along with the recommended type of cable for each group, are
provided. A matrix providing the recommended minimum spacing between
different wire groups which run in the same tray or in a separate conduit is also
provided.
ATTENTION: Steel conduit is required for all control and signal circuits when
the drive is installed in European Union countries.
