Timing Chart for INDEPENDENT START

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 If 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.
The Sequence Number Enable Bit is used when designating the sequence
number for starting operation. Execution begins from the specified sequence
number when START or INDEPENDENT START is turned ON after a
sequence number has been designated and the Sequence Number Enable
Bit turned ON.
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 #10, Sequence #20: Continuous
Sequence #11, Sequence #21: Bank end
000A Hex (10)
Speed
Sequence
#10
000A Hex
(10)
INDEPENDENT START is used for stopping at each positioning sequence. An
INDEPENDENT START operation is treated as a "terminating" positioning
sequence, stopping after a single start regardless of the completion code. A
bank end operation completion code, however, will still generate a bank end
operation.
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:
