Function Manual Basic Machine: Spindles (S1)
End of program
The following M functions are used for the end of program:
M function from
MD10714 $MN_M_NO_FCT_EOP
M2, M30
M17
If machine data MD10714 $MN_M_NO_FCT_EOP is not equal to zero, then a distinction is
made between M2 / M30 (program end of an NC program) and the M function set in
MD10714 $MN_M_NO_FCT_EOP.
Example
MD10714 $MN_M_NO_FCT_EOP = 32 means "M32" for the program end of a program
generated in the "JOG" or "MDA" operating mode.
Among other things, this functionality is required in order to continuously start the spindle in
manual operation (e.g. for scratching).
Configuring keys
If you implement a manual control using the keys on the machine control panel, then this is
realized via the following interface signals in the spindle data block:
DB3x.DBX30.0
DB3x.DBX30.1
DB3x.DBX30.2
