Communication and networking added to DC
drive
With its wide range of programmable functions, this DC drive is often used as a systems drive rather than a standalone unit and can communicate with other devices over a plant level network.
Sprint Electric has further enhanced its state of the art PLX digital DC drive with the addition of an Ethernet, CANopen, DeviceNet and Profibus DP communications capability With its wide range of programmable functions, the PLX is often used as a systems drive rather than a standalone unit, and the ability to communicate with other devices over a plant level network is a significant advantage

Sprint Electric has increased its range of digital DC drives up to 1050A for applications in the steel, plastics, rubber, and paper industries.
PLA module replaces PLC or PC based systems
A 'stand alone' PLA module with extended functionalities can compliment and enhance any analogue or digital drives system and reduce or eliminate the need for PLC or PC based systems.
Communications cards for the most widely used open industrial protocols have been developed first and Sprint is looking at adding further options including Ethernet/IP in the future.
The optional cards can be specified at the time of purchase and provide easy connectivity to the network via standard plug-in connectors.
The PLX comes with a wide range of useful peripheral software blocks built-in at no additional cost.

In recent years, the DC drive market has changed and retrofits have become an important market for DC drive manufacturers.
Regenerative four quadrant DC drives save energy
Compact regenerative four quadrant DC drives are designed to regenerate energy under braking without using complex intermediate storage, resistive dumping or additional power bridges.
Functions include high performance PID controllers, reel diameter calculator, taper tension calculator, multi-function signal processors, batch counter, spindle orientation and comparators.
The PLX provides a wide range of I/O options, with most of its terminals being universal inputs or outputs, and in all 17 digital inputs, seven digital outputs, eight analogue inputs and four analogue outputs are available.
While not intended to replace a PLC, these attributes enable the drive to perform a range of machinery control functions and now it is also able to provide diagnostic information and exchange control data with other devices and sensors via a factory floor network.
The ability to communicate via Ethernet is also a great benefit to commissioning and maintenance engineers, who can now use the web to interrogate and reconfigure the drive remotely.
Sprint, together with its North American distributor Bardac Drives, has developed Drive.web, a unique software package providing several users with access to multiple PLX drives via the Internet.
Drive.web runs on desktop or laptop PCs, enabling engineers working off site to view and adjust the drive's settings, see data on the operating status of the drive such as current and speed in real time, and diagnose and correct faults.
The Sprint PL/X range is designed to be the most compact, powerful, flexible and easy to program digital DC drive on the market.
The 4-quadrant PLX version covers the range 5 to 225kW, while the 2-quadrant PL version is available in ratings between 5 and 265kW.
The addition of a communications option makes these drives even more powerful and versatile for today's integrated manufacturing environments.
