Safety Instructions
Overview
This chapter states the safety instructions that must be followed when
installing and operating the NPBA-01 PROFIBUS Adapter Module. If
neglected, physical injury and death may follow, or damage may occur
to the frequency converter, the motor and driven equipment. The
material in this chapter must be studied before attempting any work on,
or with, the unit.
Warnings and Notes
This manual distinguishes two sorts of safety instructions. Warnings
are used to inform of conditions which can, if proper steps are not
taken, lead to a serious fault condition, physical injury and death. Notes
are used when the reader is required to pay special attention or when
there is additional information available on the subject. Notes are less
crucial than Warnings, but should not be disregarded.

in which a high voltage can cause physical injury
and/or damage equipment. The text next to this
symbol describes ways to avoid the danger.
General Warning: warns of situations which can
cause physical injury and/or damage equipment by
means other than electrical. The text next to this
symbol describes ways to avoid the danger.

General Safety
Instructions
WARNING! All electrical installation and maintenance work on the
ACS 600 should be carried out by qualified electricians.
The ACS 600 and adjoining equipment must be properly earthed.
Do not attempt any work on a powered ACS 600. After switching off the
mains, always allow the intermediate circuit capacitors 5 minutes to
discharge before working on the frequency converter, the motor or the
motor cable. It is good practice to check (with a voltage indicating
instrument) that the frequency converter is in fact discharged before
beginning work.
The ACS 600 motor cable terminals are at a dangerously high voltage
when mains power is applied, regardless of motor operation.
There can be dangerous voltages inside the ACS 600 from external
control circuits when the ACS 600 mains power is shut off. Exercise
appropriate care when working with the unit. Neglecting these
instructions can cause physical injury and death.
WARNING! There are several automatic reset functions in the
ACS 600. If selected, they reset the unit and resume operation after a
fault. These functions should not be selected if other equipment is not
compatible with this kind of operation, or dangerous situations can be
caused by such action.
More Warnings and Notes are printed at appropriate instances along
the text.

Chapter 2 – Overview
Overview
This chapter contains a short description of the PROFIBUS standard
and the NPBA-01 Adapter Module, an option package delivery
checklist, and warranty information.
PROFIBUS
PROFIBUS is an open serial communication standard that enables
data exchange between all kinds of automation components. There are
three main variations of PROFIBUS: PROFIBUS-FMS, PROFIBUS-DP
and PROFIBUS-ISP. The NPBA-01 PROFIBUS Adapter Module is
compatible with the PROFIBUS-FMS and PROFIBUS-DP protocols.
The physical transmission medium of the bus is a twisted pair cable
(according to the RS 485 standard). The maximum length of the bus
cable is 200 to 1200 metres, depending on the selected transmission
rate (see Appendix C). Up to 31 stations can be connected to the same
PROFIBUS system without the use of repeaters. With repeaters, it is
possible to connect 127 stations (including the repeaters, and the PLC)
to the system.
In PROFIBUS communication, the master station – usually a
programmable logic controller (PLC) – polls the slaves which respond
and take the actions requested by the master. It is also possible to
send a command to several slaves at the same time; in this case the
slaves send no response message to the master. Communication
between the slaves is not possible on a PROFIBUS link.
The PROFIBUS protocol family is specified in the DIN 19245 Standard,
Parts 1 to 3. The communication with a drive is discussed in
PROFIDRIVE – The PROFIBUS Profile for Adjustable Speed Drives.
For further information on PROFIBUS, refer to the above-mentioned
standards.

Chapter 2 – Overview
Installation and Start-up Guide for NPBA-01 2-2
The NPBA-01
PROFIBUS Adapter
Module
The NPBA-01 PROFIBUS Adapter Module is an optional device for
ACS 600 frequency converters which enables the connection of the
ACS 600 to a PROFIBUS system. The ACS 600 frequency converter
is considered as a slave in the PROFIBUS system. Through the
NPBA-01 PROFIBUS Adapter Module it is possible to:
• Give control commands to the drive
(Start, Stop, Direction, Run enable)
• Feed a motor speed or torque reference to the drive
• Give a process actual value or a process reference to the
PID controller of the drive
• Read status information and actual values from the drive
• Change drive parameter values
• Reset a drive fault.
The PROFIBUS commands supported by the ACS 600 and the
NPBA-01 PROFIBUS Adapter Module are discussed in Chapter 6.
The adapter module is mounted onto a standard mounting rail inside or
outside the converter unit, depending on converter type and
configuration.

Chapter 4 – Electrical Installation
Overview
This chapter contains:
• Cabling instructions
• Instructions for bus termination
• Connection and earthing instructions for the NPBA-01 module and
earthing instructions for the bus cable.
WARNING! Before installation, switch off the ACS 600 power supply.
Wait for five minutes to ensure that the intermediate circuit is
discharged. Switch off all dangerous voltages connected from external
control circuits to the digital inputs or relay outputs of the ACS 600.
Cabling
Arrange the bus cables as far away from the motor cables as possible.
Avoid parallel runs. Use bushings at cable entries.
Handle the fibre optic cables with care. The maximum long term tensile
load is 1 N and the minimum short term bend radius is 25 mm. Do not
touch the ends of the fibres with bare hands as the fibre is extremely
sensitive to dirt.
Bus Termination
The built-in terminating resistors must be switched on if the NPBA-01
module is installed at the end of the bus. Otherwise the resistors must
be switched off. Terminating resistors prevent signal reflections from
the bus cable ends.

The NPBA-01 module is connected to the frequency converter using a
fibre optic cable link. The module is designed for use with Simplex fibre
optic cables and connectors.
The bus cable and the external power supply are connected to terminal
block X2.

Earthing
The NPBA-01 module earth is internally connected to the rail onto
which the module is mounted. If the rail is fastened to an earthed
metallic assembly plate, the module is automatically earthed, and no
external earthing wire is needed. If the rail is fastened to a base that is
not earthed, the rail must be connected to the nearest earthing
terminal. However, the earthing wire should not be connected to the
same terminal as the power cable screens. (See Chapter 3, page 3-2.)
In the NPBA-01 module there are several built-in earthing terminals
(see Figure 4-3 below):
•ThePE terminal is internally connected to the NPBA-01 module
earth. Normally, no external wires need to be connected to this
terminal.
•TheSH terminal is internally connected to the NPBA-01 module
earth. The SH terminal is normally used for earthing the PROFIBUS
cable shield if there is no other station at which the cable shield is
connected directly to earth.
•TheSHF terminal is internally connected to the NPBA-01 module
earth via an RC filter. The SHF terminal is typically used for earthing
the PROFIBUS cable shield.
•TheDG terminal is isolated from the NPBA-01 module earth. This
terminal is used for connecting the third conductor of the bus cable.
The third conductor - Data Ground - offers a common reference or
comparison potential to all modules on the bus. The use of Data
Ground is highly recommended as it improves noise immunity.
Earthing the PROFIBUS
Cable Shields
The PROFIBUS cable shield may be connected straight to earth only at
one station. At other stations the cable shield should be earthed via an
RC filter (See Figure 4-3 below).

Chapter 5 – Programming
Overview
This chapter explains how to program the ACS 600 parameters to
prepare the drive for PROFIBUS communication.
For information on setting the ACS 600 parameters, read
General
below. For details, see the ACS 600 Programming Manual.
The sections NPBA-01 Module Activation and PROFIBUS
Connection Configuration (page 5-3) describe how the
communication between the ACS 600 and the NPBA-01 PROFIBUS
Adapter Module is started.
Control Locations (starting page 5-4) deals with selecting the
NPBA-01 module as the source of Start, Stop, Direction and Reference
signals. For information on how to select the actual signal from the
ACS 600 to be read through the PROFIBUS link, refer to
Analogue
Outputs , page 5-7. The selection of the NPBA-01 module as the
source of the Run enable signal and fault reset is described in System
Control Inputs, page 5-7. For information on how to define the
operation of the drive upon a NPBA-01 Module fault condition, see
Fault Functions, page 5-8.
General
The operation of the ACS 600 standard software can be changed by
adjusting the drive operating instructions called Parameters.Parameter
values can be modified with the CDP 311 Control Panel. For
information on the use of the control panel, see the ACS 600
Programming Manual .
Before programming, the NPBA-01 PROFIBUS Adapter Module should
be installed according to the instructions given in Chapters 3 and 4.
Table 5-1 (next page) presents the Parameters that should be set after
the NPBA-01 PROFIBUS Adapter Module has been mechanically and
electrically installed. The Parameters are discussed in more detail later
in this chapter. The default values refer to the Factory macro, and may
differ from the default values of other macros.
Note: The proper control of the ACS 600 by the PROFIBUS Control
Word requires that the parameters are set according to the values in
the Recommended Settings column.
Appendix F contains the listing for a type definition program, required
by Siemens master stations to configure the system for communication
with the NPBA-01 PROFIBUS Adapter Module.
