Siemens 840D 8034 - Option 'activation of axis containers' not set

Alarm 8034 occurs when the NCK attempts to activate axis container functionality but the prerequisite machine data parameter MD $MN_AXCONF_LOGIC_MACHAX_TAB has not been properly enabled. This parameter controls whether the axis configuration logic permits dynamic axis container assignment in the MACHAX table structure.

Causes and Fixes

1
Access the NCK machine data editor via HMI menu: Service > Parameters > Machine Data > NCK > Axis Configuration or use SINUMERIK Operate MD editor.
2
Navigate to parameter MD $MN_AXCONF_LOGIC_MACHAX_TAB and verify the current value. Expected value should be 1 (enabled).
3
If value is 0 or parameter does not exist, set MD $MN_AXCONF_LOGIC_MACHAX_TAB = 1 and save the configuration.
Changes to NCK machine data require a controlled stop and warm restart of the SINUMERIK system.
4
Perform a warm restart (Ctrl+Alt+Del or NCK reset) and verify alarm 8034 clears when axis container activation is again attempted.
