Access axis parameter menu

Navigate to MOD > Machine Parameters > Axes and select the affected axis %2 from the alarm message.

Note the current state of all three controllers before making changes

Check controller status parameters

Verify parameters P-AXIS-00013 (position controller enable), P-AXIS-00014 (speed controller enable), and P-AXIS-00015 (current controller enable) status.

Do not change parameters while machine is in automatic mode

Execute proper shutdown sequence

Set position controller to OFF first, wait for confirmation, then speed controller OFF, finally current controller OFF.

Allow 2-3 seconds between each controller shutdown step

Perform desired activation/deactivation

Now execute the intended controller state change and restart controllers in reverse order: current, speed, then position.

Ensure axis is mechanically secured before reactivating controllers

Check program execution status

Press PGM MGT key and verify no programs are in RUN or INTERRUPTED state. Check status line for active program indicators.

Look for blinking RUN indicator or program line highlighting

Stop active program execution

Press STOP key to halt program execution, then press END key to completely terminate the program if needed.

Ensure workpiece and tooling are in safe positions before stopping program

Switch to Manual mode

Turn mode selector to Manual (MAN) or Electronic Handwheel (HW) to ensure no automatic program control is active.

Manual mode gives you direct control over axis controllers

Retry controller operation

Now attempt the controller activation/deactivation procedure that originally triggered the alarm.

Verify all axes are properly referenced before switching back to automatic modes

Access servo parameters

Navigate to MOD > Machine Parameters > Servo and locate parameters for axis %2 showing in the alarm.

Use parameter search function (GOTO PARAM) to quickly find axis-specific settings

Check servo enable parameters

Verify P-AXIS-00020 (servo enable source) and P-AXIS-00021 (servo enable logic) are correctly configured for your machine setup.

Incorrect servo enable settings can cause unexpected machine behavior

Verify safety interlock parameters

Check P-AXIS-00030 through P-AXIS-00035 safety-related parameters to ensure no conflicts with controller state changes.

Safety interlocks may prevent controller changes even when technically possible

Reset servo system

Perform controlled servo system reset via MOD > Reset > Servo Reset, then retry the controller operation.

Servo reset will require axis re-referencing before normal operation

Check PLC status display

Press PLC key to access PLC status screen and look for active M-functions or servo control signals for the affected axis.

Look for M-functions in 40-49 range which often control servo states

Review active PLC markers

Check PLC markers M4000-M4999 range for axis-specific servo enable signals that may be active.

Do not manually change PLC markers without understanding their function

Clear active M-functions

If servo-related M-functions are active, execute appropriate M-function to release PLC control (typically M05, M09, or machine-specific codes).

Consult machine manual for specific M-function sequences to release axis control

Verify PLC release and retry

Confirm PLC no longer shows active servo control signals, then attempt the controller state change operation again.

Ensure machine safety systems remain active when releasing PLC control
