NISA-03 DDCS/ISA Adapter
The NISA-03 DDCS/ISA Adapter is an interface board for controlling
ABB ACS 600 Product Family drives (later referred to as ACx 600) from
a personal desktop computer. The board enables the use of DriveWare
PC software, e.g. DriveWindow. The NISA-03 occupies a standard
16-bit ISA slot on the computer motherboard.
The optical signal is connected to the NAMC (Application and Motor
Control Board) of the ACx 600 with fibre optic cables. The signal can be
distributed to several drives using NDBU Series Branching Units; refer
to the NDBU documentation on more information on this feature.
The NISA-03 has two DDCS-protocol optical channels, one equipped
with 5 megabaud optical components, the other with 10 megabaud
optical components. The channel to use depends on the board it is
connected to. The diagram below presents the boards as well as cable
types and lengths that can be used with each NISA-03 channel.

2 Installation Instructions for NISA-03
WARNING! Do not work on a powered ACx 600. Before installation,
switch off the mains and other dangerous voltages (e.g. from external
control circuits) to the ACx 600. After switching off the mains, always
allow the intermediate circuit capacitors 5 minutes to discharge before
commencing work on the frequency converter.
WARNING! The component boards of both a personal computer and
the ACx 600 contain integrated circuits that are extremely sensitive to
electrostatic discharge (ESD). Wear an earthing wrist band when
handling component boards. Do not touch the boards unnecessarily.
Do not remove the NISA-03 from its antistatic packaging until required.
WARNING! Handle the fibre optic cables with care. The maximum long
term tensile load is 1 N; the minimum short term bend radius is 35 mm.
Do not touch the ends of the fibres with bare hands as the fibre is
extremely sensitive to dirt. When running the cables into the ACx 600
converter unit, use rubber grommets at cable entries to protect the
Installation Procedure 1. Switch off the PC and all its peripherals. Disconnect the mains
2. Switch off the mains supply and other dangerous voltages (e.g.
from external control circuits) to the ACx 600.
3. Remove the PC cover. Check that no existing boards use the same
addressing space with the NISA-03.
The default base I/O address for the NISA-03 is 280H. (The
NISA-03 requires 32 consecutive locations.) If this address is
already used by another board on the system, 2A0H can be
selected using the DIP switches as shown below. (DIP switch IAS3
is not used.)
Note: When installing new boards on the computer system, it is a
good practice to write down the I/O addresses, as it helps the
addition of other cards later, and makes troubleshooting easier if

4. Locate an available 16-bit ISA card slot. Remove the expansion
slot cover and screw. (Keep the screw.)
5. Press the NISA-03 Adapter into the slot evenly and firmly. Use the
screw from the slot cover to fasten the NISA-03 into its place.
6. Close the PC cover.
Before proceeding, make sure that the intermediate circuit capacitors
in the ACx 600 have discharged. (Before starting work on the ACx 600,
wait at least 5 minutes after switching off the mains supply.)
7. Open the front cover (or door) of the ACx 600. Locate the NAMC
(or NDBU) board. (The actual location of the boards inside the
drive vary depending on drive type.) Lead the fibre optic cables to
the inside of the drive. Use grommets at cable lead-throughs.
8. Inside the ACx 600, connect the fibre optic cables to Channel 3
(terminals V19 and V20) on the NAMC board. (On NDBU
Branching Unit, the incoming cables are connected to the MSTR
channel.) Observe connector colour codes.
9. At the PC, connect the fibre optic cables to the appropriate
NISA-03 channel (CH0 or CH1; see first page). Observe connector
10. Close the front cover (or door) of the ACx 600.
