The heart of the Elite®Pro is a high speed Digital Signal Processor (DSP) designed specifically for motor control applications. The speed and processing power of the DSP are further enhanced by the skillful use of five (5) additional co-processors to handle critical high speed timing functions as well as keypad and external communications. Therefore, the resulting design is very capable of handling basic control algorithms along with advanced algorithms for system functions such as PID Dancer Controls, Center Winder Controls, Tension Controls, and Customized Control Functions to meet user requirements. The power section design for the Elite®Pro follows the same conservative design practice that Carotron's customers have come to appreciate in all of Carotron's designs. We provide a regenerative and non-regenerative drive chassis package that is capable of full load operation in a 55¾ C ambient. Compare this to our competitors that design to ambient levels of 35¾ to 50¾ C. Standard customer interface to the Elite®Pro is via a four-line alphanumeric, backlighted LCD display. English text and menu screens with soft-keys simplify the drive programming and eliminates the need to memorize numeric codes. A User programmable section is provided to allow frequently used monitoring screens or programming screens to be located together for specific machine functions. Two levels of password protection can be activated to prevent unwanted changes of drive parameters. RS-232 and RS-422 communications also allow interface to computers and PLC's.

Standard Features

MULTIPLE PROCESSORS

The Carotron Elite¨Pro has been designed with control loop speed and accuracy in mind. As a result, our control is equipped with 1 digital signal processor (DSP) and 5 microprocessors. The DSP is responsible for the Current Control Loop, Velocity Control Loop and I/O Functions. Three of the microprocessors are used to generate the firing signals to each of the SCRs. The other 2 microprocessors handle the Keypad and Communication functions. The final payoff is a DC Drive with superior speed and torque regulation, as compared with most Digital DC Drives.

ON BOARD EEPROM

One of the great advantages of the Elite¨Pro is the on board EE PROM. EE PROM is a user modifiable read-only memory that can be erased and reprogrammed. Since the program code is stored here, field upgrades are made easy. In other words, software upgrades or application specific changes can be made without sending the unit back to the factory.

DIGITAL OPERATOR

The Elite¨Pro has been equipped with an enhanced operator panel as a standard. The operator panel displays text messages on a 20 character x 4 line backlighted LCD display. Text messages can often eliminate the need to look up parameter codes in the instruction manual. Five soft keys are used to maneuver around in the simple menu structure of the Elite¨Pro. Additionally, the operator panel stays mounted on the driveÕs control board even when the front cover is removed. The operator panel can also be remote mounted up to 1000 feet away with an optional NEMA 4 mounting kit and simple communication cable.

COMMUNICATIONS

Many Users and OEMÕs have already recognized the benefits of serial communications with motor controllers. The lower cost of engineering and installation combined with enhanced flexibility make this an attractive low cost alternative to control wiring. Many products offer serial communications only as an option. The Elite¨ Pro comes with RS-232/RS-422 capability right out of the box.

SHUNT FIELD REGULATOR

The on board Field Regulator has two modes of operation. In the standard mode, the regulator supplies the standard 150/247/300VDC depending on the input voltage supply. In the closed loop mode, the shunt field current is regulated thus providing improved performance throughout the motorÕs temperature range. This mode of operation along with the regulators ability to be used with an external voltage source makes it easy for the Elite¨Pro to be used with motors that have non-standard field voltages.

FUTURE OPTIONS
