$MM_ST_DEFAULT_MACHINING_SENSE
Basic settings for machining direction – milling
Min. input limit: 0
Protection level: 3/4
This MD is used to stipulate the basic setting for the direction of machining rotation when
milling, except for track milling.
0 = Reverse
1 = Synchronous
The basic setting only has an effect in the case of newly created programs.
$MM_ST_SPINDLE_CHUCK_TYPES
Type of spindle chuck
Min. input limit: –
Protection level: 3/4
This MD is used to stipulate which edge is measured for the counter–spindle. This edge
then acts automatically as reference point when moving the counter–spindle.
Bit 0 = 0: Counter–spindle without jaw dimensions (dimensions of front edge)
Bit 0 = 1: Counter–spindle with jaw dimensions (dimensions of stop edge)
Or, alternatively, you can make these settings in the "Tools zero offset" menu → ">" →
"Spindles" in the "Jaw type" parameter. Changes to the MD are automatically transferred to
the parameter and vice versa.
$MM_ST_SPINDLE_P ARA_ZL0
Chuck dimension for main spindle
Min. input limit: –
Protection level: 3/4
This MD is used to stipulate the chuck dimension ZL0 of the main spindle. The chuck di-
mensions are required when you use the chuck of the main spindle as reference point for
manual tool measurement.
Or, alternatively, you can make these settings in the "Tools zero offset" menu → ">" →
"Spindles" in parameter "ZL0". Changes to the MD are automatically transferred to the pa-
rameter and vice versa.
$MM_ST_SPINDLE_P ARA_ZL1
Chuck dimension for counter–spindle
Min. input limit: –
Protection level: 3/4
This MD is used to stipulate the chuck dimension ZL1 of the counter–spindle. The chuck
dimensions are required when you use the chuck of the counter–spindle as reference point
for manual tool measurement. You also need the chuck dimensions for determining the
reference point when moving the counter–spindle (see MD 9829
$MM_ST_SPINDLE_CHUCK_TYPES).
Or, alternatively, you can make these settings in the "Tools zero offset" menu → ">" →
"Spindles" in parameter "ZL1". Changes to the MD are automatically transferred to the pa-
rameter and vice versa.
