Single Facer Control

A single facer control mainly comprises three parts: single face, overhead conveyor, and roll stand. 

Unico’s Smart Velocity Drive is a digital signal processor (DSP) based variable-speed drive with an embedded software block to control a single facer. The program offers several programmable features that enable OEMs, integrators, and users to customize the functionality of the software to the application. Our single facer control’s essential characteristics are the automatic splice control option, flexibility and ease of use, smart AC digital drives, communication protocols, and many others. 

With our single facer control, you not only control the process but can also customize the equipment to serve your needs better.

Features

Modes of Operation

The 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.

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.

Automatic Splice Control Option

An automatic splice control option permits splicing at speeds up to 1200 fpm (400 mpm). Additional drives, motors, and Unico’s 4000 Series controller are required. Since mechanical modifications are necessary, the option may not be available on some older machines.

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.
