Individual blocks or a sequence of blocks can be executed with the machine,
without creating a program.
Blocks are input to the memory of the control via the keyboard. The system
provides programs MDA1...6 for each channel (MDA1 for channel 1, MDA2
for channel 2, etc.).
When you press NC Start, the control processes the blocks. You can set
CLEAR (CLR) under program modification to determine whether the block
sequence is to be cleared after processing. If CLR is not active, the block
sequence is retained after processing.
Used, for example, in connection with operations in "JOG" mode.
