PA Industries Edge Servo Roll Feed SRF-100(for Serial Numbers 7610697 and higher) - Manual (Page 5)

These parameters are set from the factory for
average feeding applications and they seldom
require any changes. The five screens and a brief
explanation of the parameters are described below:
• LENGTH: Distance in inches (or millimeters) of
the feed length. Maximum value of 4015 inches.
• COUNT: The number of pieces required to run
in the batch. Maximum value of 999,999 pieces.
• SPEED: The maximum velocity of the material
in inches/second (or millimeters/second).
Maximum value of 100 inches/second.
☞
• ACCEL: The rate of acceleration in
inches/second 2 (or millimeters/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: Following 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.
