Product Overview
DC590+ DRV Series DC Digital Drive
Product Range
The DC590+ DRV contains the DC590+ controller, a contactor and ac supply fusing. An optional control transformer, motor blower and dynamic
brake are also available.
System Design
The 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. 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 controllers 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 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 DC590+ DRV Series includes both regenerative and non-regenerative models:
•
Regenerative drives
consist of two fully-controlled thyristor bridges, contactors, fuses, 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 drives
consist of one fully-controlled thyristor bridge, contactors, fuses, 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 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. The field current mode of operation can be
further enhanced to provide field weakening for controlling motors in extended speed or constant horsepower control.
