ULTRA ADVANTAGE SERVO ROLL FEED 2/14/2003

The “Jog Forward” Operator button will function until the end of the “Feed Length” is reached. During “JTL” mode,

the bottom line on the display will show “Waiting for Jog”. When the “Feed Length” is reached, the jog buttons

become inactive and the message on display will show “Waiting for Press”. The jog buttons will not become active

again until after the press has made a cycle.

5.4 “AUTO / MANUAL” MODE

“Auto” Mode is used for production running of the UltraAdvantage Servo Roll Feed. When “Manual” mode is selected

via the 2-position selector switch, the control can be put in “Auto” mode by pressing Cycle Start button.

During “Manual” mode, the feeder can be jogged infinitely in either direction. After the Cycle Start button is pressed,

the jog buttons are inactive, and the feeding of the strip follows the cam signals from the press.

During “Auto” mode, the control keeps check on synchronization of the feeder and the press. If the feeder does not

complete the index within the feed cam window, the message “SYNC FAULT” displays.

The Ultra Advantage Servo Roll Feed has 2 modes of automatic cycling. The feeder can operate with Single Stroke or

Continuous modes. The mode is selected through an input to the feed controller. The Press single stroke/continuous

mode switch should be interfaced to that input for proper operation. During single stroke mode operation, the “Permit

Press” relay is activated upon the completion of each feed index.

The “Permit Press” relay remains activated until the reset cam signal turns on, or for the duration of the Dwell, if the

Dwell parameter is programmed. The “Permit Press” relay may be used to signal the press when to initiate the single

stroke cycle. The automatic cycling of the press and feeder will continue until the batch is completed, or the cycle is

stopped by the Operator, or an error occurs.

During “Continuous Press” mode, the “Permit Press” relay turns on at the beginning of the indexing.

The “Permit Press” relay remains activated until the automatic cycling is stopped by either “Cycle Stop” button, “Batch

Complete” internal command, “Sync Fault” or any other drive related error. Under “Cycle Stop” or “Batch Complete”

stopping, the output will turn off at the beginning of the Feed Cam Signal. This should allow the press to stop near the top

of the stroke. Under “Sync Fault” or other drive fault conditions, the “Permit Press” relay will turn off immediately

upon detection of the error.

5.5 STRIP ENCODER OPERATION

The control is designed such that if there is no Strip Encoder attached to the Servo Drive or the measuring wheel

is lifted, the Servo Drive and the whole feed acts as regular feed, operation of which is described in this Manual.

The measuring wheel must be lowered and the Length Mode must be set up before Cycle Start button is pressed.

Refer to STRIP ENCODER-OPERATION section of this manual for Length Mode description.

There are four additional SETUP parameters that take care of proper Strip Encoder operation. They are as follows:

Length Mode is a parameter that selects whether the feeder works in the Control or Check mode. Entering a "0" selects

Control mode and "I" selects Check mode.

Length Check is a parameter that defines the Check mode tolerance. It is a numeric entry with a range of 0.00 to

5.00 inch.

Strip Scale is the Strip Encoder scaling parameter used to define the number of encoder counts/inch. It is a numeric

entry with a factory value 3386.17.

Kp Multiplier is a parameter that defines a proportional gain of the position loop of the Strip Encoder and based on the

value of the motor encoder's Kp proportional gain. This is a tuning parameter, before changing its value, consult the

P/A Industries Service Department.
