    OPERATING PROCEDURE Control panel Once the connections between the lathe and the feeder have been completed, functions F1 to F8 have to be set so that the feeder can work in optimum conditions. Operation of the control panel TD 200 To access functions F1 to F4, directly press the buttons.

  • Page 42: Functions

    Functions F1 - F8 (All measurements given are in millimeters) F1 : Software version including date issued (press for 2 seconds) F2 : Pusher-bar position limit The pusher-bar tends to flex as it leaves the device. As a result, in a given position, it might touch the inside of the spindle.
  • Page 43 F5 : Safety length The parameter F5 confirms the position of the new bar in the lathe chuck. If the bar is blocked somewhere, the feeder will sound an alarm. Enter the correct setting: F5 = Distance between the positioning sensor LS1 and the tip of the lathe chuck. F6 : End of bar point This parameter indicates the limit to which the pusher-bar may advance behind the lathe...
