This section provides timing charts showing START and INDEPENDENT
START execution. The X axis is used as an example. It is first necessary to
understand the functions of the Busy Flag and the Sequence Number Enable
Bit.
Turns ON while axes are outputting pulses. Turns OFF when execution is
completed. No new start can be executed while the Busy Flag is ON.
Note In an absolute move command to the present position or a relative move com-
mand with position data of 0 is executed (i.e., when a linear movement is
made with a travel distance of 0), the Busy Flag will be turned ON for one
cycle at startup.
DIFU R1
Sets the total number of
MOV
write words. In this case,
012C
sets to 12C (Hex).
(100 positioning sequences
D00500
× 3 words = 300 words)
Sets the area in the CPU Unit
MOV
used to set the positioning
#000E
sequences (EM Area, bank 0).
D00501
Set the beginning word of the
MOV
area in the DM or EM Area used
#0000
to set the positioning sequences.
D00502 In this case, sets to 0000.
Sets the beginning address of the
MOV
area in the PCU to which the
#1000
positioning sequences are to be
D00503 written. In this case, sets to 1000.
