INTERFACING SERVO FEED WITH A PRESS
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 then 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 letting the rollers return to a holding position for the next move.
The roll release adjustment screw is located at the entrance of the feed. The screw is
used to limit the travel of the roller during release. Adjustment may be necessary if
using air pilot release and speed is a factor. 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 and pilot signal input and wire per print.
These inputs are brought down to a terminal strip for your convenience. The feed input
number is (J55-1) and the pilot input number is (J55-2).
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.
