Adjust the follower torque settings

WHAT YOU NEED 

Standard Personal Protective Equipment

CAUTIONWhen using the manual mode, make sure that everything and everyone is clear of moving parts to prevent damage or injuries.

  1. Rehome the saw.

  2. Using the Manual Mode window, feed a straight 6‑m-long timber into the saw so that the trailing end of the board is in the middle of the AIT conveyor.

    Note: make sure the board is securely clamped in both feeders and can move at least 2 m in either direction without hitting the follower end stops.

  3. Open the PEWIN32PRO program.
  4. Select Watch Window from the View drop-down menu at the top of the PEWIN32PRO window.
  5. Press the Insert key and add the TestPrintMoveErrMin (P981) and TestPrintMoveErrMax (P982) variables to the Watch Window.

  6. Type "Q281=1" in the terminal window and press the Enter key to position the follower against the board.

    CAUTIONThis will engage the follower at full speed with no audible warning. Make sure that everything and everyone is clear of the follower.

  7. In the terminal window, set the following variables (press the Enter key to confirm each one):

    • "Q796=10" (Velocity Compensation Pressure)
    • "Q784=35" (Normal Pressure Torque)
    • "Q789=30" (Dynamic Pressure Torque)
  8. Type "&1b11r" and press the Enter key.
  9. Type "P983=1" to move the follower and board to the left. Watch for the follower paddle to stay in contact with the board while moving.
  10. Type "P983=-1" to move the follower and board to the right. Watch for the follower paddle to stay in contact with the board while moving.
  11. If the follower paddle does not stay in contact with the board, increase Q784 and Q789 evenly up to respectively 45 and 40. Repeat from step 9 until set correctly.
  12. If the follower paddle still does not stay in contact with the board once both Q784 and Q789 have reached their maximum value, increase Q796 progressively up to 12. Repeat from step 9 until set correctly.

  13. Make sure the error readings in the Watch Window do not exceed 3 mm.

    Note: if either reading exceeds 3 mm (absolute value), contact Vekta Automation for further assistance.

  14. Type "&1a" in the terminal window and press the Enter key.
  15. Press and hold the CONTROL button on the operator console for 5 seconds to release the timber and return the follower.
  16. Type "save" and press the Enter key.
