590 Series Digital Converter
1GETTING STARTED
Introduction
System Design
The 590 Series Converter is designed for use in a suitable enclosure, with associated control
equipment. The unit accepts standard three-phase ac supply voltages in the range 110V to 660V,
depending upon the model, and is suitable for the powering of DC shunt field and permanent
magnet motors, providing controlled dc output voltage and current for armature and field.
All units are designed for simple and economical panel mounting using keyhole slots. Plug-in
control connectors simplify the fitting and removal of the unit to the panel.
Where possible, standard parts are used throughout the range thereby reducing the variety of
spare parts required to maintain a multi-drive system. For example, the same basic control
boards are used in all types of three-phase armature controller regardless of horsepower or
bridge configuration.
The control circuit is totally isolated from the power circuit thus simplifying the interconnection
of controllers within a system and improving operator safety. The coding circuitry adjusts
automatically to accept supply frequencies between 45-65Hz and possesses high immunity to
supply-borne interference. The armature controllers are phase rotation insensitive.
Control and Communications
The Converter is controlled by a 16 bit Microcontroller providing advanced features such as:
•Complex control algorithms which are not achievable by simple analog techniques.
•Software-configurable control circuitry built around standard software blocks.
•Serial link communications with other drives or a PC for advanced process systems.
The integral Man-Machine Interface (MMI), with a two-line 16 character display, is a powerful
diagnostic tool. It provides access to all alarms, inputs and principal software blocks in the
controller, whilst the front panel LED indicators give an immediate status display of the drive,
key inputs and outputs.
Regenerative and Non-Regenerative Models
The motor armature controllers include both regenerative and non-regenerative models:
•Regenerative controllers consist of two fully-controlled thyristor bridges and a field bridge
with full transient and overload protection, together with sophisticated electronic control of
acceleration and deceleration, speed and torque in both directions of rotation.
•Non-regenerative controllers consist of one fully-controlled thyristor bridge and a field
bridge with full transient and overload protection, together with its associated electronic
control circuitry, and provide accurate speed and/or torque control in one selected direction
of rotation.
Field Regulator
A field regulator is fitted as standard. The regulator consists of a full-wave half controlled single
phase thyristor bridge with transient and overload protection. It provides either a fixed voltage
or fixed current source, depending upon the selected mode of operation for constant torque
applications. The field current mode of operation can be further enhanced to provide field
weakening for drive control motors which require extended speed or constant horsepower
control.

Equipment Inspection and Storage
•Check for signs of transit damage
•Check the product code on the rating label conforms to your requirement.
If the unit is not being installed immediately, store the unit in a well-ventilated place away from
high temperatures, humidity, dust, or metal particles.
Refer to Chapter 2: “An Overview of the Converter” to check the rating label/product code.
Refer to Chapter 8: “Routine Maintenance and Repair” for information on returning damaged
goods.
Refer to Chapter 11: “Technical Specifications” - Environmental Details for the storage
temperature.
Packaging and Lifting Details
Caution
The packaging is combustible and, if disposed of in this manner incorrectly, may lead to
the generation of lethal toxic fumes.
Save the packaging in case of return. Improper packaging can result in transit damage.
Use a safe and suitable lifting procedure when moving the drive. Never lift the drive by its
terminal connections. The larger drives are fitted with lifting points.
Prepare a clear, flat surface to receive the drive before attempting to move it. Do not damage
any terminal connections when putting the drive down.
Refer to Chapter 11: “Technical Specifications” - Mechanical Details for unit weights.
About this Manual
This manual is intended for use by the installer, user and programmer of the 590 Converter. It
assumes a reasonable level of understanding in these three disciplines.
Note: Please read all Safety Information before proceeding with the installation and operation
of this unit.
Enter the “Model No” from the rating label into the table at the front of this manual. There is
also a column for you to record your application’s parameter settings in the table in Chapter 10.

12AN OVERVIEW OF THE CONVERTER
How it Works
Note: Refer to Chapter 9: “Control Loops” for a more detailed explanation.
In very simple terms, the Converter controls the dc motor with the use of Control Loops - an
inner Current Loop and an outer Speed Loop. These control loops can be seen in the Application
Block Diagram. The block diagram shows all the Converter’s software connections.
Using the Man-Machine Interface (MMI), you can select the control loops to be used by the
Converter to provide either:
•Current Control
•Speed Control (default)
It is usual to supply a Current or Speed Feedback signal to the appropriate loop for more
effective control of the Converter. Current Feedback sensors are built-in, whereas Speed
Feedback is provided directly from the armature sensing circuit (default), or by tachogenerator,
encoder or Microtach connection to the relevant option board.
When in Speed Control,
you can modify the
performance of the
Converter further by
controlling the motor
field, i.e. Field Control.
By weakening the field
current, you can obtain
an increase in motor
speed beyond that
normally achievable for
the rated Armature
Voltage of the dc motor.
The Converter is controlled remotely using digital/analog inputs and outputs. It cannot be
directly stopped or started using the MMI.
A remote 5721 Operator Station can also be connected. This allows you to read and write to
many of the drive’s parameters from outside the cubicle if required.
By plugging in a COMMS Option Board, the Converter can be linked into a network and
controlled by a PLC/SCADA or other intelligent device.
