Fundamentals
15.9 Spindle data
CNC Part 1 (NCK, PLC, drive)
300 Commissioning Manual, 11/2006, 6FC5397-2AP10-2BA0
Configurable M function
The M function, which switches the spindle to axis mode, can be configured in machine data:
MD20094 $MC_SPIND_RIGID_TAPPING_M_NR.
The value on delivery is 70.
Functionality
If the axis mode is active and the rotary axis homed, all axis functions can be used.

The most important functions are:
• Programming with axis name
• Use of zero offsets (G54, G55, TRANS, etc.)
• G90, G91, IC, AC, DC, ACP, ACN
• Use of kinematic transformations (e.g., transmit)
• Interpolation with other axes (path interpolation)
• Programming as a positioning axis
Special points to be noted
• The feed override switch is active.
• NC/PLC IS:
DB21, ... DBX7.7 (Reset)
does not terminate axis mode as standard.
• NC/PLC IS:
DBB16 to DBB19 and DBB82 to DBB91 in DB31, ...
are of no significance if NC/PLC IS:
DB31, ... DBX60.0 (Axis/No spindle)
is set to zero.
• Axis mode can be activated in all gear steps.
If the position actual-value encoder is installed on the motor (indirect measurement
system), the positioning and contouring accuracy may vary for the different gear steps.
• The gear step cannot be changed when the axis mode is active.
The spindle must be switched to control mode.
This is done with M41 ... M45 and M5, SPCOF.
• In axis mode, the machine data of the parameter set with index zero are effective in order
to carry out adaptation in this mode.
Transition to axis mode
Transition to axis mode by programming:
• The spindle with its own identifier or by M70 and by means of the M function:
MD20094 $MC_SPIND_RIGID_TAPPING_M_NR
• The relevant machine data when changing the servo parameter set are:
