14. Use the Up and Down Arrow buttons to go to the next parameter to be modified.
Repeat as required for any remaining parameters.
15. When all program modifications are completed, use the Up and Down Arrow
buttons to go to parameter “0” then press the Enter button to return to run mode.
16. Remove the power source from the controller. Following the procedures in your
facility, lockout or tagout the power source.
17. Remove the dust cover from the control enclosure.
18. At the connection end of the drive lift the black plastic cover up slightly then
slide it out of the back of the drive.
19. Locate the jumper labeled “JP1”.
20. Move the JP1 jumper from the “ON” position to the “OFF” position.
21. Slide the black plastic cover back into position.
22. Install the enclosure cover.
23. Remove any lockout/tagout devices in use as per procedures in place at your
facility, then connect the controller to the power source and power the unit up.
24. The drive is now ready to be used.
The required programming values for Extruder Tracking Control are located on
drawing number A0541236, one of three drawings that are included with the additive
feeder. If you do not have these drawings contact service to have them forwarded to
you.
Parameter # 37 requires the installer to program the correct pulses per revolution from
the extrusion machine.(See Chapter 5)
Extruder Tracking Control Application Notes
Input Pulse Signal Requirements
The drive uses a 5 volt DC square wave (TTL NPN type RPM signal) on its S2 input terminal
as a reference signal from the extruder. Please contact us for application assistance if your
extruder is not equipped with a method to provide this signal.
Minimum Input Pulse Rate
Extruder Tracking units are programmed to follow an extruder that provides eight pulses per
revolution. Additive Feeders used in extruder tracking systems REQUIRE end user
programming to match the master rate signal from the extruder’s screw if the signal
does NOT provide eight pulses per revolution. The value programmed into parameter P37
must be set to match the number of pulses per revolution that the extruder generates.
In addition, the drive must be provided a MINIMUM of 240 pulses per minute to provide
accurate results.
