07.97 6 NC Machine Data (NC MD), NC Setting Data (NC SD)
6.3 Channel-specific MD (channel data)
• The function can also be switched off via the PLC (Program control, DB10-15, DR14, bit 3,
DL2, bit 3).
The channel-specific initial settings for ZO (G54 - G57) and TO (D number 0 - 819) after
POWER On are defined in NC MD 140* and 142*. With these values it is possible to determine
the state of the control (in terms of ZO and TO) after Power On.
Note:
See Programming Guide, Workpiece-related Actual Value System.

See machine data 3 for a description of MD 146* to 150*
Note for MD 146*, 148* and 150*:
If the value of the machine data in question is 0, machine data 3 is used for that corner
deceleration speed.
