Marker M4054 is set for the battery-free TS 444 touch probe (MP6010 = 3)
when the touch probe is ready for operation (M4050) and the supply voltage
for the battery-free touch probe is too low. If no touch probe is connected, the
value of marker M4054 is undefined. Power is supplied to the battery-free
touch probe by compressed air driving an integrated air turbine generator. The
capacitor in the touch probe stores energy for approx. two minutes of
continuous operation. Evaluation of marker M4054 makes it possible to
purposefully control the supply of compressed air.
The NC takes over control of the probing process. Certain conditions are
indicated in M4050 to M4054.
M4050 Touch probe not ready, ready signal
is missing
M4051 Stylus deflected before start of
probing cycle
M4052 Stylus is deflected, probing process
is completed
M4053 Probing process has been completed
or canceled
M4054 Battery voltage too low (battery
warning at touch probe connection);
evaluated only during the probing
a
process
M4055 Enable the probing process
M4056 NC stop in all operating modes if
stylus is deflected
M4057 Touch probe cycles active
(FN17: ID990 NR2)
a. is only supported for the battery-free TS 444 touch probe
(MP6010 = 3).
