    Bridgeport Interact 720VMC auto lube parameters

    I was adjusting my tapping deceleration and also looking over some other parameters in the technical manual when I saw the X,Y,Z and 4th axis automatic lubrication parameters. I have TNC2500 control and was wondering what other people are using for these values. The range is 0...65535 (in units of 65536 um). I'm assuming it is micro meters? All of mine are set to 0.

    Parameters related to lubrication system:

    4110.5 - 25000
    4110.6 - 200
    4110.7 - 210
    4120.0 - 3

    And the unit is not um. 0...65535 is in the unit of PLC cycle, 1 cycle = 24msec.
    Parameters above will provide you with 30minute of lubrication cycle, 5 sec of lubrication On time, and 4.8 sec of time-out limit for lubrication pressure.

    I have parameter 4060.0 as X, 4060.1 as Y, 4060.2 as Z, and 4060.3 as 4th axis under the automatic lubrication section in the tech manual.

    4110.5,6,7,8 etc. are for PLC programmed durations for timers 0-47, durations of 24 in ms. I'm not sure where to find what each timer does..
