Programming via synchronized actions

M functions M40 to M45 can also be programmed in synchronized actions.

Please note:

The programming of M40 ... M45 in the part program has no effect on the current status of the automatic gear

step change of synchronized actions, and vice versa.

When programming S values with M40, automatic gear step change is effective separately for synchronized

actions and the part program.

M40 is deactivated after POWER ON.

The gear step is not adjusted if an S value is specified from a synchronized action.

An M40 command programmed using synchronized actions always remains active for synchronized actions

(modal) and is not reset on reset.

M41 ... M45 selects first to fifth gear steps in accordance with the programming in the part program.

An axis replacement is necessary in order to run the function.

Once the gear step change has been performed, the spindle status is neutral (same response to M3, M4, M5

programming).

For further explanations regarding the programming of the spindle as well as spindle movements from

synchronized actions, refer to:

Function Manual, Synchronized Actions

When the PLC specifies the direction of rotation and speed using FC18, the NCK can determine and select a

gear step to match the speed. This is equivalent to the M40 functionality when programming via the part program.

The correct start code must be set when FC18 is called in a PLC user program, in order to activate gear step
