where the following applies:
– $System variable
– SSetting data

Activation
Activation when referring to a machine data indicates the NC status in which a change to a
machine data becomes active.
The levels of effectiveness have been listed below in order of priority. Modification of the
machine data takes effect after:
• POWER ON (po) NCK RESET
• NEWCONF (cf)
– Softkey Activate MD at MMC
– RESET key on MCP
– It is possible to modify block limits during program operation
• RESET (re)
– at end of program M2/M30 or
– RESET key on MCP
• IMMEDIATE (so)
– After entry of value
Note
Unlike machine data, changes to setting data always become effective immediately.
