4.10 Load monitoring (optional)
Refer to your machine manual.
This function must be set up by your machine
manufacturer.

load monitoring feature in
Program run submode:
Define the respective machine parameters in the
System section

load monitoring with G996 and the monitoring zone
with
G995
in your program

Programming User's Manual
During a machining operation with active load monitoring, the
control compares the current utilization of the drives specified
by
G995
with the respective limit values. To calculate the limit
values for a monitoring zone defined with G995 , the control uses
reference values determined during reference machining as well as
predefined factors specified in the machine parameters.
If the utilization limit 1 or the limit of the utilization sum is
exceeded, the control issues a warning and sets the corresponding
diagnostic bits in
Tool editor
mode of operation to identify the
active tool as worn-out .
If the utilization limit 2 is exceeded, the control issues an
error message, stops the machining operation and sets the
corresponding diagnostic bits in
Tool editor mode of operation to
identify the active tool as broken .
You can manage the diagnostic bits in Tool editor mode of
operation.
Further information:
"Diagnostic bits", Page 570
If tool life monitoring is active, the control will
automatically insert a predefined replacement tool
during the next tool call in order to replace the tool
that has been flagged as worn-out or broken . As an
alternative to the automatic evaluation of the diagnostic
bits by the tool life monitoring function, you can also
evaluate the diagnostic bits in your program.
