Application
example(s)
Can be evaluated by machine manufacturer in order to activate the test on NC start.
The following must be set in the drive machine data:
MD1012 $MD_FUNC_SWITCH, bit 2 = 0.
Status "Ext. pulse disable active, terminal 663 open" is then not transmitted to the NC.
Corresponding to .... MD1012 $MD_FUNC_SWITCH, bit 2
