PA Industries Magnum Servo Roll Feed SRF-M12/18/24/32/36/48 - Installation and Operating Instructions - Manual (Page 5)

• SPEED: The maximum velocity of the material
in inches/second (or millimeter/second).
Maximum value of 60 inches/second.
☞
• ACCEL: The rate of acceleration in
inches/second 2 (or millimeter/second 2 ).
Maximum value of 1000 inches/second 2 .
• DWELL: The time delay which controls the ‘ ON ’
duration of the cut output relay. The dwell is used
when the press or shear, lacks a continue Bottom
Dead Center (
BDC ) switch and the cycle can be
controlled by the dwell parameter.
• DBNC: This is the debounce parameter, which
is used to ignore contact bounce on the feed
signals.
☞
• PRIORITY: This parameter selects whether the
feeder indexes before the press starts ‘ FBP ’
(Feed-Before-Press), or the press starts before
the feeder indexes ‘
PBF ’ (Press-Before-Feed).
Entering a ‘ 0 ’ selects ‘ PBF ’ mode or a ‘ 1 ’ selects
‘ FBP ’ mode.
• BACKLIGHT: This turns on the backlight in the
display, which enhances the viewing.
☞
• CNTS/UNIT: This is the encoder scaling
parameter used to define the number encoder
counts/inch (or counts/millimeter).
• TIME BASE: Time scaling parameter for various
parameters. This is always set to ‘ /SEC ’ by
entering ‘ 0 ’.
• JOG SPEED: The rate of jogging speed in
percent of the SPEED parameter. Normally set
between 1 - 5%.
• DIRECTION: This parameter controls the
direction of positive motor rotation. 0 = CCW,
and 1 = CW.
☞
• KP: Proportional gain parameter for the motion
control. It controls the transitions between the
starting and stopping of the rolls. A lower value
provides a smoother (slower) transition.
• KD: This parameter is not used.
• KFF: Velocity feed forward gain. This is used to
reduce following error of the system.
• AUTO OFFSET: This parameter turns the
automatic offset on. Turn this feature on by
entering ‘
1 ’.
☞
• INPOSN: In-position parameter is a tolerance
window around the final position. This is used to
verify the feed index accuracy is within acceptable
limits before continuing onto the next function.
• FELim: Follower error limit. FELim is the
maximum allowed position error. When this limit
is exceeded for the amount of time specified by
the FETime, the control will execute an
emergency stop.
• FETime: Follower error time. FETime is the
maximum amount of time that the following error
limit may be exceeded before executing an
emergency stop.
• SYSTEM RESET: This function clears all
parameters to the factory default conditions. No
program may be running,
RESET must be active
(press and hold the ‘ POWER ON ’ button), and
the ‘ PROG/RUN ’ switch must be set to ‘ PROG ’
position. Pressing ‘ 1 ’ while the cursor is on the
SYSTEM RESET line will result in a confirmation
screen being displayed. Pressing ‘ 1 ’ a second
time will reset the parameters to the factory
default values and the power-up screen will be
displayed. Pressing any other key than ‘
1 ’ will
result in aborting the system reset.
4.1 PROGRAM A NEW FEED
LENGTH, COUNT, SPEED
To program a new feed pitch/length the program
must be stopped. This may be done by pressing the
‘
POWER ON ’ or the ‘ CYCLE STOP ’ button
(if the press is running). Press the ‘ OPERATOR ’
button to view the following screen:
