CHAPTER 1: INTRODUCTION
1.1 Overview
1.1.1
The HE300DNT100 is a plug-in Option card to the GE AF300E$
or IMO JaguarVX Inverter
which allows remote control of a drive through the DeviceNet
network. This Option card allows network
access to the Inverter’s configuration, control and status parameters. Configuration parameters may be
accessed either remotely over the network or through the local keypad. Similarly, control and status
parameters may be accessed through the high-speed DeviceNet
“Polled” logical connection or through
the local terminal and keypad. Manual override contacts are provided on the Option card, which allow
real-time selection of either remote or local control.
1.1.2
The supported DeviceNet
service is a Group-2-server-only with a single Poll Data I/O
connection with fragmentation. This is a predefined master/slave protocol supported by almost all
DeviceNet
scanners. A DeviceNet
Polled connection watchdog timer is provided such that a loss of
communications will shut down the drive. Network configuration and connection error diagnostic
information is available in an “option” function code, which is accessible through the Inverter’s keypad.
2.1 Additional Information
2.1.1
Inverter wiring, configuration and operation are included with the manuals supplied with the
Inverter.
3.1 Mechanical Description
3.1.1
The HE300DNT100 Option Board is a printed circuit assembly that mounts inside the housing of
the Inverter. It connects to the Inverter through a multiple-pin connector, which is located under the front
cover and next to the keypad connector. It also has a Phoenix-type 6-pin I/O vertical receptacle
connector (Horner APG, LLC. provides the matching 6-pin screw terminal connector) which is used to
connect a DeviceNet
cable (dual twisted pairs with shield). In addition, a Phoenix-type 2-pin screw
terminal, which is used to connect an optional remote override switch, is provided.
4.1 Electrical Description
4.1.1
The Option Board contains its own microprocessor and memory. It communicates with the
Inverter through a provided serial communications channel. This serial communications channel provides
access to the drive’s control, status and configuration parameters. An internal watchdog timer and
network diagnostics are provided. Connectors are provided for the DeviceNet
and manual override
connections.
