The display should now show the new setting:

These (3) parameters may be changed when the
running batch is stopped. All other feeder
parameters are locked out of the editing mode via
‘
RUN/PROGRAM ’ switch located inside the
electrical enclosure on the panel.
5. OPERATING THE FEED
5.1 PRIORITY MODE
The Edge Servo Roll Feed has (2) modes
of automatic cycle starting. The Operator can
choose 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 the ‘ CYCLE START ’
button is pressed on the feed control, the material/
strip will be fed forward the programmed pitch
before the press is started. The Operator may verify
that the strip is in position before starting the press.
The Edge Servo Roll Feed will now follow the
press until it is stopped by the Operator, counter,
emergency stop, or feed error.
5.2 SET-UP MODE
‘ SET-UP 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 ‘ SET-UP MODE ’, the strip may be moved
using the ‘ JOG FORWARD ’ operator button. If
the ‘ JOG FORWARD ’ is stopped before the ‘ FEED
LENGTH’ is reached, then either the ‘ JOG FOR-
WARD ’, or ‘ 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 REVERSE ’
operator button will function until the end of the
‘
FEED LENGTH’ is reached.
During ‘ SET-UP 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 the display will show
‘
WAITING FOR JOG ’. The jog buttons will not
become active again until after the press has made a
cycle.
5.3 AUTO/MANUAL MODE
‘ AUTO MODE ’ is used for production running of
the Edge Servo Roll Feed. When ‘ AUTO ’ is selected
via the 2-position selector switch, the control is put
into ‘
MANUAL MODE ’ until the ‘ CYCLE START ’
button is pressed. During ‘ MANUAL MODE ’, the
feeder may be jogged infinitely in either direction.
After the ‘
CYCLE START ’ button is pushed, 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 press. If the
Feeder does not complete the index within the feed
cam window, the message ‘
SYNC FAULT ’ displays.
The Edge Servo Roll Feed has (2) modes of
automatic cycling. The feeder can operate with
‘
SINGLE STROKE ’ or ‘ CONTINUOUS PRESS
MODE ’. The mode is selected through an input
to the feed controller. The press single
‘
STROKE/CONTINUOUS MODE ’ switch should be
interfaced to this input for proper operation.
During ‘
SINGLE STROKE MODE ’ operation, the
‘ PERMIT PRESS ’ output relay is activated upon
the completion of each feed index. The ‘ PERMIT
PRESS OUTPUT RELAY ’ remains active until the
continue cam signal turns on. The ‘ PERMIT
PRESS OUTPUT 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 OUTPUT RELAY ’ turns on at the
beginning of the indexing. The ‘ PERMIT PRESS
RELAY ’ remains active until the automatic cycling
is stopped by either ‘ CYCLE STOP ’ , ‘ BATCH
COMPLETE ’ , ‘ SYNC FAULT ’, or any other drive
NOTE:
It is very important to remember that the motor
on the Edge Servo Roll Feed is only for feeding
material. It is not intended to be the power
source for a pull-through straightening device,
or the like. An adequate free loop must be
provided at all times. This will assure consistent
and accurate feeding.
