AWT ELECTRICAL CABINET SETTINGS 350,500 ,600
TEN - VR:
Used to calibrate the wire tension settings.
Sensing Adjust Knob: Set to 30.
This sets the sensitivity of the buckling sensor on the AWT unit. A lower setting makes it
more sensitive to the wire buckling. Set it lower if the AWT drive rollers don’t rewind
the wire if it buckles between the drive rollers and the water jet pipe.
BB3:
Sets the reverse tension on the wire spool when jogging the Z axis up and down. The
back tension sw toggle switch turns the BB3 function on and off.
Speed Control Unit: Set to 11 or 12 o’clock position.
This controls the speed of the drive rollers and the AWT pipe speed on the AWT unit.
Setting it further clockwise makes the drive rollers feed the wire faster when it is
threading the wire. This unit is recognizable by its orange knob.
If you adjust the speed of this unit, adjust the parameter AWT 2 FEED TIME (SEC)
