Timing Chart for Memory Operation
Section 8-8
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 re-executed while the Sequence Number Enable Bit is OFF,
the sequence numbers executed will be the same as those for INDEPEN-
DENT START.
8-8-5
Timing of Data Changes during Memory Operation
It is possible to change positioning sequences and the data used in position-
ing sequences, such as speeds, positions, and acceleration times, during
memory operation. When performing positioning with the completion code set
to continuous, however, there will be a delay in the timing with which data
changes are reflected in operation.
When positioning sequences with completion codes set to continuous are
being executed continuously, the PCU reads up to 3 positioning sequences at
the start of memory operation. This means that if changes to data for a posi-
tioning sequence are not made during execution of the positioning sequence
at least 3 sequences before, these changes will not be reflected in operation.
