Slitter / Scorer Control

Our smart velocity drive is a digital signal processor (DSP) based variable speed drive with an embedded software block to control a slitter/scorer. The program offers a number of programmable features that enable OEMs, integrators, and users to customize the functionality of the software to the application. These features include modes of operation, lineal tracking, flexible and easy to use, duplex/triplex option, smart AC digital drives, communication protocols, and many input-output options.

With Unico technology, you can also get specific models that will be custom-made for you and your particular needs.

Features

Communication Protocols

The drive supports a variety of serial communication protocols for connecting to virtually any PLC or HMI. The drive can also operate in a stand-alone mode using the built-in keypad/display with an ANSI protocol connection to a simple serial display unit.

Inputs & Outputs

All inputs and outputs are user-enabled and are mapped to hardware I/O points to allow customization of the control. They are also accessible through a high-speed serial communication link.

Modes of Operation

The embedded software has manual and automatic/run modes of operation. In manual mode, the drive can be jogged in both directions. In automatic/run mode, velocity cruise control is enabled and two parallel inputs are used to increase or decrease motor velocity. A third input is used to command the drive to return to a previous speed.

Flexibility and Ease of Use

The software allows the user to easily adjust the velocity and acceleration rates as well as to set up and tune the drive. Fault messages and warning indications are provided for the machine operator. An alphanumeric display shows current drive speed, drive state, and drive status. Analog outputs are available to provide other drives or controls with proportional references of drive speed and/or torque. The drive supports UEdit®, Unico’s Windows-based IEC 1131 standard ladder-logic and function-block programming package that provides even greater customization and flexibility. The drive is ideal for retrofits and seamlessly interfaces into existing logic and with other logic controllers.

Duplex/Triplex Rotate Option

A duplex/triplex rotate option facilitates automatic rotation of the slitter heads into position during the automatic-order-change sequence. An additional motor and smart drive are required. When the web is severed, the program tracks the tail and rotates the heads automatically based upon the tracking position. Index and rotate angles are programmable. When the heads are in position, a permissive allows the line to ramp up speed and resume normal operation.

Smart AC Digital Drives

Unico’s 1000 and 2000 drive families provide powerful, flexible digital flux vector control for sophisticated, performance-oriented applications. The drives have been designed for complete flexibility and offer a variety of feedback, programmable I/O, and communication options. They incorporate a number of energy-conserving features, including line regenerative capabilities for exporting energy back to the power grid. Both drive families can take advantage of a modular DC bus configuration for sharing or recirculating energy among multiple drives.
