DZERO - Invalidate D numbers
The activation of this command invalidates all D numbers of the tools in the TO unit. It is no longer possible to
activate a compensation until valid D numbers are again available in the NCK. The D numbers must be
reassigned using the SETDNO command.
The following tools must be defined (all with cutting edge number 1):
The following command is then programmed:
If one of the compensations is now activated (e.g., with T3 D100), an alarm is generated, because D100 is not
currently defined.
The D numbers are redefined with:
Note
If a further cutting edge has been defined for the tool, e.g., $TC_DPCE[ 1, 2 ] = 1 ; = CE, the
D-number 2 of the cutting edge 1 cannot have the same name as the D-number of the cutting
edge 3 i.e.: SETDNO( 1, 1, 17) returns the status = FALSE as return value.
T1, D1
D no. of cutting edge CE=1
T2, D10
D no. of cutting edge CE=1
T3, D100
D no. of cutting edge CE=1
DZERO
SETDNO( 1, 1, 100 ) ;T=1, cutting edge 1 receives the (new) D number 100
SETDNO( 2, 1, 10 ) ;T=2, cutting edge 1 receives the (old) D number 10
SETDNO( 3, 1, 1 ) ;T=3, cutting edge 1 receives the (new) D number 1
Note
In the event of a power failure, the DZERO command can leave the NCK in an undefined state
with reference to the D numbers. If this happens, repeat the DZERO command when the
power is restored.
