point to the spindle.
n is the actual location number (n ≠ 0) to be entered by the PLC user program in the variable transfer
table.
9.7.3 Example: Tool change cycle for turning machine
Transfer variables of the T replacement cycle:
The "Replacement tools for tool management" option is not active.
Prerequisite is that the tool management has been informed of each magazine movement.
With MD10717:
$MN_T_NO_FCT_CYCLE_NAME (name of the cycle that should be executed
instead of the T function, e.g. "TCHANGE"), you can set that a cycle is run through when the
T command is called. The cycle is run through at every T call, irrespective of whether a new
tool or the already active tool is called. The position of the turret can be set on the programmed
tool in this cycle (POSM). This is necessary when the turret has been positioned manually after
a tool selection and the tool has not been deselected. In this case, the NC does not issue a
new job for tool change at the interface.
