Rapid-Air SERVO FEED: 100C, 100D series - Manual (Page 7)


The Servo Drive unit is a slave to the
press therefore it needs a command
from the press to operate in the
automatic mode.
The command is in the form of a
normally open contact from a limit
switch, cam switch or an electronic
feed interface device that can be
programmed.
The contact should be commanded
or activated at 270 degrees of the
press stroke or when the tooling is
clear of the material and released or
turned off at around 350 degrees of
the press stroke. The significance of
the release position is to insure that
the feed switch is released with the
press top stopped. Once the program
senses a closure of the feed input,
it will command a move and will
complete the move regardless of
the switch position.
The air operated pilot release also
has to have a signal input to

operate. The pilot signal should be
set to turn on when the point of the
pilot is entering the hole. This signal
them commands air roll release to
raise and release the material, letting
the pin pull the material forward into
position. The release should be
then commanded to turn off at
approximately 180 degrees letting the
rollers return to a holding position for
the next move.
The roll release stop adjustment
screw is located at the entrance
of the feed. (See drawing for your
servo). The screw is used to limit the
travel of the roller during release.
Adjustment may be necessary if
using air pilot release at a somewhat
high speed with the pilot release
deactivating and feed switch
activating at a close proximity with
each other in degrees of press stroke.
To adjust, insert material into the feed,
lower rolls, adjust screw, using 3/16
hex wrench, to full in. Release rolls
and adjust screw so the material is
free to be pulled in by the pilot pin.
The adjustment is now complete.
(NOTE: This adjustment does limit
the manual roll release travel.
If this causes a problem back off
the adjustment a little.)
The schematic in the back of this
manual points out the switch or
contact connections for wiring the
interface. Locate the feed input and
wire per print. This input is brought
down to a terminal strip for your
convenience. The feed input
number is (J52)TB1-2) and the pilot
input number is (J52)TB1-4).
This completes the initial setup of
the servo feed to the press or other
device. The servo is now ready to
run as intended.
If more complete interfacing is
needed, please refer to the section
(interfacing ) in this manual for an
explanation of inputs and ouputs
available.
