Suppress touch probe monitoring
Suppress touch probe monitoring
If the stylus is deflected, the control issues an error message as
soon as you want to move a machine axis.
You must deactivate touch-probe monitoring in the
Manual
operation
mode in order to use a positioning block to retract a
touch probe after it has deflected.
You can deactivate touch-probe monitoring for 30 seconds with the
TCH PROBE MONITOR OFF
soft key.
The control issues the error
message
The touch probe monitor is deactivated for 30 seconds
.
The error message automatically clears itself after 30 seconds.
If the touch probe receives a stable signal within the
30 seconds, such as "Touch probe not deflected," then
touch-probe monitoring reactivates itself automatically
and the error message is cleared.
NOTICE
Danger of collision!
The
TCH PROBE MONITOR OFF
soft key suppresses the
corresponding error message if the stylus is deflected. The
control does not perform an automatic collision check with the
stylus. Because of this behavior, you must check whether the
touch probe can retract safely. There is a risk of collision if you
choose the wrong direction for retraction.
Carefully move the axes in the
Manual operation
mode
Functions in touch probe cycles
Soft keys that are used to select the probing direction or a probing
routine are displayed in the manual touch probe cycles. The soft
keys displayed vary depending on the respective cycle:
