21.10 Measuring cycles and measurement functions
Tool measurement using the "Orientable tool holder" or "Swivel tool" function
If the general cycle machine data MD52740 $MNS_MEA_FUNCTION_MASK, bit 16 = 1, then
the following setting applies:
MD51618 $MNS_MEA_CM_ROT_AX_POS_TOL
= 0.5
The real angular position of rotary axes can deviate from that programmed (exact stop fine
window) This deviation depends on the position control properties of the axis. The maximum
deviation that can be expected at a specific axis should be entered into the parameter. When
the tolerance is exceeded, Alarm 61442 is output - "Tool holder not parallel to the geometry
axes".
21.10.5 Logging
21.10.5.1 Logging the measuring, general
General logging can be performed without special settings:
● In the passive file system of the NC
● On the local drive of the CF card
If you want to use a logical drive for the logging, you require the Execution from External
Storage (EES) function, see Chapter "Setting the EES (Page 82)".
General machine data
Logging can be controlled via the following machine data settings:
MD11420 $MN_LEN_PROTOCOL_FILE
Increase the value of machine data MD11420 if larger log files have to be stored in the file
system of the NC.
MD11422 $MN_PROTOCOL_FILE_MODE
Bit 0
Note
Set MD11422 bit 0 = 1 so that the program runtimes are not lengthened significantly.
