ACR7000 CONTROLLER Hardware Installation Guide 45
Overview
The ACR7000 Controller communicates in a standard Ethernet network, thereby providing a direct link for
sending commands through the Parker Motion Manager software installed on a PC. This chapter describes how to
establish the standard Ethernet connection.
The controllers have a dual-stack, standard RJ-45 connector, which provides two communications ports. The two
ports act as a hub, with a single IP address.
Ethernet Specifications
Ethernet Cable Specification
Use a braid over foil twisted pair cable (straight or crossover) for connection to a PC. An example of this type of
cable is L-COM TRD855SIG-XX. The maximum recommended cable length is 30m.
Ethernet Connector
A standard RJ-45 socket connector, located on the front panel of the drive/controller, provides two
communication ports that accommodate ETHERNET connections. The two sockets of the connector are identical,
and either may be used for direct connection to a PC network card.
To provide top noise performance, the connector contains isolation transformers and common mode chokes for
both the transmit and receive signal pairs.
