Boundary conditions

M and T functions for tool change in a block

If, in addition to the M function replacement with parameter transfer, a T function

replacement was configured, the following behavior is applicable in case of a conflict, i.e., T

and M function for tool change are in one block:

• The T function replacement does not take place. Instead, the T value is made available to

the M function replacement via the appropriate $C_T... system variables.

• The programming of the address T in the M function subroutine does not result in another

replacement.

Note

Configuration of MD10718 $MN_M_NO_FCT_CYCLE_PAR:

The configuration of a replacement subroutine for the tool change with M code is

dependent on whether the tool change with M code was actually configured with

MD22550 $MC_TOOL_CHANGE_MODE.
