Feed-to-Stop Control

Our FTS™ software module is engineered specifically for controlling roll-feed applications.

Our FTS™ software module is engineered specifically for controlling roll-feed applications. The program is embedded within the controller of a Unico drive, eliminating the need for an external control rack. 

When used in conjunction with a programmable controller, the drive forms a powerful automation work cell that can either stand-alone or be easily integrated with other Unico automation cells to build a complete control system for a metal-processing line. Embedded control reduces system complexity while taking full advantage of the exceptional performance, flexibility, and ease of use of Unico drives.


Single-Stroking Profile Mode

In this mode, the feeder follows an internally simulated profile using the feed initiate and cut engage inputs to control the feed cycle. The feeder starts the feed when the feed initiate input is set. When the feed is complete, the feed complete output is set. The shear can then be cycled to clear feed initiate and set the cut engage bit. When cut engage is set, the feed complete output is cleared. As the shear continues to cycle, the feed initiate input is again set to start another feed.

Synchronous Profile Mode

In synchronous profile mode, the feeder is electronically line-shafted to the press or shear. It follows an external reference signal, typically a pulse generator or a resolver mounted on the press or shear. By taking advantage of the full feed angle, this mode results in higher production rates while minimizing slippage. The feeder responds quickly to changes in line speed, allowing the line to accelerate rapidly without the risk of jamming. The feeder never operates faster than is necessary, thereby minimizing violence in the loop between the feeder and the leveler.

Trapezoidal Mode

Trapezoidal feeding smoothes the command by rounding the sharp corners of the velocity profile. While most feeders operate in a profiling mode, the trapezoidal mode can be used to attain the lowest speed for a given length.

Single Feed

The single feed function feeds one length at a pre-programmed speed. The single feed input must be toggled for subsequent single feeds.


The feeder can be commanded to reverse slightly after the shear or press has gone through the bottom dead center. This reduces material drag on the rising blade and improves blade life. It also helps prevent damage to the leading edge of the material.

Micro Adjust

The micro-adjust feature minutely adjusts the feed length by adding or subtracting a programmable offset to the current feed length.

Quick Length Change

Lengths may be quickly changed on the fly by entering a new length into the next length location, then setting an input to make the changeover.

Multiple Part Counting

The operator can specify the number of parts to be counted in applications where multiple pieces are cut or stamped with each feed or die hit.


The operator can set up batches consisting of a number of feeds of a given length that the drive will perform before stopping.

Early Warning

An early warning output is set when the batch is nearly completed. The output can be used to alert the operator or to slow the line down.

Velocity Clamping

The feed velocity may be clamped to a reference or input velocity. In conjunction with loop control, this feature can be used to control line speed on shear lines.

Pilot Pins

Pilot pins are typically used to align the indexed feed within a die. The feeder reduces its torque limit when the pilot pin is engaged in the material to allow the alignment to occur. When the pilot pin is released, the feeder can either reset its position using the newly aligned position as its zero points or maintain its current position.

Press Cam Outputs

The program monitors the feedback device on the press or shear and generates up to eight outputs that can be configured to turn on or off at specified press positions. These outputs can trigger various other line functions and replace mechanical cam switches.


A reject function is provided to allow the operator to reject material of in specified lengths. A reject output may be used externally for proper counting and stacking.

Feed and Delay

A programmable delay allows the user to adjust the time between the completion of a feed and the firing of the shear to meet machine requirements.

Line Pulse Generator

While most feeders operate using a line pulse generator (LPG) to track material movement, some lines do not have a measuring wheel or operate without an LPG at certain times. An input allows the user to selectively enable and disable this functionality.


The control can be customized to a specific installation using UEdit™, a powerful Windows-based programming tool that lets users add their own ladder logic and function block programming.

Inputs & Outputs

A variety of input/output functions are provided for integrating the feed-to-stop control with external devices. The user can select the functions required by a given system and specify their corresponding hardware or serial I/O points.
