When INDEPENDENT START is re-executed while the Sequence Number
Enable Bit is OFF, the sequence numbers executed will be as follows:
Prior condition
INDEPENDENT START from OFF to ON
when Sequence Number Enable Bit is
Start
Completion code
when Sequence Number Enable Bit is
OFF
Independent start
Terminating
Continuous
Automatic
Previously executed sequence number
+1
Bank end
Sequence number when previous
Sequence Number Enable is ON.
Start
Terminating
Previously executed sequence number
+1
Continuous
Automatic
Will not stop when completion code is
continuous or automatic.
Bank end
Sequence number when previous
Sequence Number Enable is ON.
Deceleration stop
Input CW/CCW limit.

8-8-4 Timing Chart for START
START begins execution from any sequence number in accordance with the
completion code set for each positioning sequence. When a sequence number
with its completion code set to terminating or bank end is executed, pulse output
stops when positioning is completed, and then waits for START.
In the following timing chart the completion codes for the positioning sequences
are as follows, using X-axis operation for a 4-axis PCU as an example:
Sequence #0, Sequence #3: Continuous
Sequence #1: Terminating
Sequence #2: Automatic
Sequence #4: Bank end

Note
If START is turned from OFF to ON when the Sequence Number Enable Bit is
OFF after a power-up or a restart, the sequence number error (error code 8101)
will be generated.
When START is is re-executed while the Sequence Number Enable Bit is OFF,
the sequence numbers executed will be the same as those for INDEPENDENT
START.
