Timing Chart for Memory Operation
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.
8-8-1
Busy Flag
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.

Sets the total number of
write words. In this case,
sets to 12C (Hex).
(100 positioning sequences
×
3 words = 300 words)
Sets the area in the CPU Unit
used to set the positioning
sequences (EM Area, bank 0).
Set the beginning word of the
area in the DM or EM Area used
to set the positioning sequences.
In this case, sets to 0000.
Sets the beginning address of the
area in the PCU to which the
positioning sequences are to be
written. In this case, sets to 1000.
