Introduction Chapter 3 contains both a general description of the major hardware
components of the Series A 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 40 – 100HP, 230VAC and 75 – 200HP, 460VAC Series A Drives.
Terminology A brief description of new terms and concepts covered in Chapter 3 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 3.1 provides an overview of the hardware components associated
with the Series A 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.
Important: Refer to Chapter 1, “Publication References” for manuals
describing larger horsepower and current ratings at other line
voltages.
