Product Overview 2-1
Product Range
The DC590+ Series DC Digital Drive is designed for use in a suitable enclosure, with associated control equipment. The unit accepts a variety of
standard three-phase ac supply voltages 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 drive is controlled by a 32 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 Keypad gives access to parameters, diagnostic messages, trip settings and full application programming.
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.

How it Works
NOTE
Refer to Chapter 5: “Control Loops” for a more detailed explanation.
In very simple terms, the drive controls the dc motor with the use of
speed increase
Control Loops - an inner Current Loop and an outer Speed Loop. These
due to field
control loops can be seen in the Application Block Diagram. The block
weakening
Armature
diagram shows all the drive's software connections.

Using the Keypad, you can select the control loops to be used by the

drive to provide either:
• Current Control

• Speed Control (default)
It is usual to supply a Current or Speed Feedback signal to the
base
appropriate loop for more effective control of the drive. 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 drive 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 drive is controlled remotely using digital/analog inputs and outputs, or locally using the Keypad. By plugging in a COMMS Option Technology
Box, the drive can be linked into a network and controlled by a PLC/SCADA or other intelligent device.

Keypads
The drive is fitted with the 6901 Keypad.
It provides Local control of the drive, monitoring and complete access for application programming.
For example, you can start and stop the motor, check on diagnostic information, and change parameters values on the drive.
The keypad fits to the front of the drive, however, you can also remote-mount the keypad up to 3 metres away.
Alternatively, you can fit a 6911 keypad. The 6911 provides a larger screen and improved functionality.
For remote-mounting, you’ll need the correct Remote Mounting Kit. Refer to Chapter 6: "The Keypad".

Mechanical Installation
IMPORTANT Read Appendix B: “Certification" before installing this unit. Refer to “Installation Drawings”, page 3-75 for further
information. Note the additional information for Frame 6 and Frame H at the end of this Chapter.
Unpacking the Drive
Caution
The packaging is combustible and this action may produce lethal
toxic fumes.
Save the packaging in case of return. Improper packaging can result in transit
damage.
Frame H Packaging
Large drives (Frame H) are supplied in special packaging bolted to a pallet
with removable sides. Remove all fixings from the pallet.
Figure 3- 1 Lifting Details (Frame H)
Lifting the Drive
Use a safe and suitable lifting procedure when moving the drive. Never lift the drive by its terminal connections. 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.
Frame 4 & 5 drives have lifting eyes and a shipping plate fitted to the base to enable the drive to be lifted into position, or to be set-on-end by a forklift.
Remove the shipping plate before wiring the power terminals.
Frame H drives require the following:
• The drive is supplied with a lifting bracket fitted to each corner for hoisting. Remove the brackets when the drive is in its final position, however,
the bracket fixings MUST be re-fitted. Refer to Appendix E: “Technical Specifications” - Termination Tightening Torques (Frame H).
• A shipping plate is fitted to the base to enable the drive to be set-on-end by a forklift. Remove the plate before wiring the power terminals.
