5 OPERATING THE ULTRA MAGNUM SERVO FEED
5.1 PROGRAMMING
There is no need to program anything if the “Tool Storage” is properly set up. It is only matter of activating the
needed tool, although the OPERATOR screen allows the Operator to edit two basic parameters.
OPERATOR screen is the only one that is Operator editable. This screen displays Length, Count, and Length
Adjustment. Length and Count can be changed only when cycling is stopped, although Length can be adjusted by
using the LENGTH ADJUSTMENT command even while the feed is running.
When Length and Count are edited or adjusted from OPERATOR screen, they override the stored tool Length and
Count and will be active until current tool is reactivated or another tool is activated.
Activate tool is the only command that is Operator accessible and can be executed only when the feed is not cycling.
5.2 PRIORITY MODE
The Ultra Magnum Servo Roll Feed has two modes of automatic cycle starting. The choice can be made between
“Press – Before – Feed” (“PBF”) and “Feed – Before – Press” (“FBP”) operating mode.
When “PBF” mode is selected and the Cycle Start button is pressed on the control panel, the feeder causes the “Auto”
and “Permit Press” relays to turn on thus enabling the start of continuous cycling on the press.
When “FBP” is selected and Cycle Start button is pressed on the feed control, the material/strip will be fed forward
before the press is started. The Operator may verify that the strip is in position before starting the press.
The Ultra Magnum Servo Roll Feed will now follow the press until it is stopped by the Operator, counter, emergency
stop, or feed error.
5.3 “JTL” (JOG TO LENGTH) MODE
“JTL” mode is used primarily during the threading of the strip through the die. This mode allows the Jog – To –
“Feed Length” operations to be performed. While in the “JTL” mode, the strip may be moved using the remote Jog
Pendant.
If the “Jog Forward” is stopped before the “Feed Length” is reached, then either the “Jog Forward” or the “Jog
Reverse” Operator buttons will work. The “Jog Reverse” will not allow the strip to go backwards beyond the initial
“Feed Length” starting point.
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 Magnum 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.
