Introduction Chapter 2 contains both a general description of the major hardware
components of the 1395 drive and background information to support the
procedures detailed in other chapters of this manual. You should use this
chapter in conjunction with the Installation chapter when installing 400 –
600 HP, 230VAC, and 700 – 1250 HP, 460VAC and 1000 – 2000 HP, 660
VAC Series A Drives.
Terminology A brief description of new terms and concepts covered in Chapter 2 is
presented here:
Adapter Board – Circuit board containing hardware and software required
to interface external devices such as Allen-Bradley PLC or Discrete I/O
devices to the 1395 drive.
Interface – Hardware and associated software required to transfer
information and/or control signals from one device to another.
Microbus – Hardware and associated software designed by Allen-Bradley
for the exchange of digital information at the microprocessor level. The
microbus is used for the transfer of information between adapter boards
and the main control board.
Port – Hardware located on the main control board which allows for
connection of one adapter board to the microbus. There are two ports on
the main control board.
Programming Terminal – Device used for programming and monitoring
operation on the 1395 drive. The programming terminal is provided in two
packages: digital handheld terminal and door-mounted terminal.
Hardware Overview Figure 2.1 provides an overview of the hardware components associated
with the high horsepower 1395 drive. Hardware can be broken into one of
three categories:
•
Control boards
•
Control/Power interface hardware.
•
Power hardware
This chapter describes in general all of the major hardware components.
Figures provided in this chapter are drawn based on hardware
functionality. Some components may be repeated in several different
diagrams.
