Procedure When Using Toolholders With Orientation Capability - Siemens SINUMERIK 840D sl Function Manual

Language command PAROT is not rejected if no toolholder with orientation capability is active.
This causes no changes in the programmed frame.
Note
For further information about the TCARR and TOROT as well as PAROT functions with regard
to channel-specific system frames, see Section "K2: Axis Types, Coordinate Systems,
Frames (Page 661)".

Procedure when using toolholders with orientation capability

Creating a toolholder
The number of available toolholder data sets in the NCK is defined with machine data:
MD18088 $MN_MM_NUM_TOOL_CARRIER (maximum number of definable tool carriers)
1. The value is calculated as follows:
MD18088 = "Number of TO units" * "Number of toolholder data sets of a TO unit"
MD18088/"number of TO units" is permanently allocated to each TO unit.
Note
For further explanations on the definition and assignment of a TO unit by machine data:
MD28085 $MC_MM_LINK_TOA_UNIT (assignment of a TO unit to a channel (SRAM))

2. Zero setting of toolholder data:
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.
3. Accessing the data of a toolholder:
– Part program
– OPI interface
The parameters of a toolholder with orientation capability can be read and written with the
NCKHMI (OPI) variable services using system variable $P_TCANG[<n>].
4. Data backup:
The system variables specified above are saved as part of the general NCK data backup.

→ $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.
