Introduction
This manual describes the GV3000/SE™ ControlNet™ Network Communication
Option Board (M/N 2CN3000). This board lets you operate and monitor a GV3000/SE
drive over the ControlNet network.
For normal operation, the GV3000/SE drive can be completely controlled using the
Network Option board. The only connections you need are a network interface
connection, hardwired emergency stop, and three-phase input and output power
wiring. Start, stop, reset, fault codes, and complete control can be done over the
ControlNet network.
1.1 About the ControlNet Network Communication
Option Board
The ControlNet Network Communication Option Board makes the GV3000/SE drive a
node on the ControlNet network. It is a printed circuit board assembly that mounts
inside a GV3000/SE drive and connects to the drive’s Regulator board using a ribbon
cable. The Network Option board is powered from the standard drive power supply.
The Network Option board is equipped with flash memory that lets you easily update
the board with the latest firmware revisions without having to remove the board from
the drive. An RS-232C serial port lets you connect a serial programming device to the
Network Option board for updating the board’s flash memory.
The Network Option board connects to the ControlNet network using two BNC
connectors that provide for redundant communication. You can connect a
programming device for accessing nodes using the Network Access Port, which is an
RJ-45 connector.
Three LEDs provide information to you about the board. Refer to chapter 8 for
descriptions of how the LEDs function.
See figure 1.1 for the locations of the connectors and LEDs.
