Syntax
Table 8- 1 Identify machining step:
STOPFIFO
...
STARTFIFO
Table 8- 2 Automatic preprocessing memory control:
...
FIFOCTRL
...
Table 8- 3 Preprocessing stop:
...
STOPRE
...
Note
The
STOPFIFO, STARTFIFO, FIFOCTRL, and STOPRE commands have to be programmed in a
separate block.
Significance
STOPFIFO: STOPFIFO identifies the start of a machining step to be buffered in the
preprocessing memory.
STOPFIFO stops processing and fills the
preprocessing memory until:
•
STARTFIFO or STOPRE is detected
or
• The preprocessing memory is full
or
• The end of the program is reached
STARTFIFO: STARTFIFO starts rapid processing of the machining step; the
preprocessing memory is filled in parallel to this.
FIFOCTRL: Activation of automatic preprocessing memory control
STOPRE: Stop preprocessing
