The value on delivery is 70.
Note
From software version 2.6, the control system detects the transition to axis mode
automatically from the program sequence (see "Implicit transition to axis mode [Page
1280]"). Therefore, there is no need at all for the explicit programming in the part program of
the configured M function for switching the spindle to axis mode (default: M70). However, the
M function can continue to be programmed, e.g. to increase the readability of the part
program.
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.
• The NC/PLC interface signals:
DB31, ... DBB16 to DBB19 and DBB82 to DBB91
are not important if:
DB31, ... DBX60.0 (axis / no spindle) = 0
• Axis mode can be activated in all gear steps.
If the position actual value encoder is installed on the motor (indirect measuring system), the positioning and
contouring accuracy can 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 or M5, SPCOF.
• In axis mode, the machine data from the servo parameter set with index zero are effective in order to carry out
adaptations in this mode.
