Selecting the toolholder
A toolholder with number m is selected with the NC program command TCARR = m (TCARR
Tool Carrier).
TCARR = 0 deselects an active toolholder.
New tool or new toolholder
When a new tool is activated, it is always treated as if it was mounted on the active
toolholder.
2-100
You can use the command
$TC_CARR1[0] = 0
to zero all values of all data sets.
Individual toolholder data sets can be deleted selectively with the NC command DELTC or
the PI service _N_DELTCAR.
– Part program
→ $TC_CARRn[m] = value
This describes the previous value of the system variables n for toolholder m with the
new value "value".
→ value = $TC_CARRn[m]
With "def real value" - the parameters of a toolholder m can be read if they have
already been defined (e.g., set MD18088). Otherwise, an alarm is signaled.
– OPI interface
The parameters of a toolholder with orientation capability can be read and written with the
NCKMMC (OPI) variable services using system variable $P_TCANG[<n>].
The system variables specified above are saved as part of the general NCK data backup.
