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.

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:

SETDNO( 1, 1, 100 )

SETDNO( 2, 1, 10 )

SETDNO( 3, 1, 1 )

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.
