7-4-5 Starting Direct Operation During Memory Operation
Direct operation can be used even during memory operation, by bringing the
active axis to a decelerated stop. The interrupted sequence number will be
retained as long as new sequence numbers are not set and provided an origin
search or an origin return is not executed, or the present position is reset.
When memory operation is restarted, the interrupted sequence number will be
executed. Positioning in memory operation after direct operation has been used
will vary according to the absolute and relative positions in the position data.
Absolute Movement Memory Operation
Relative Movement Memory Operation
Movements from P0 to P1 to P2 to P3 to P0
are all executed with absolute position data.
While moving from P2 to P3, stop with a
deceleration stop and move to P4 in a
direct operation.
When memory operation is re-started, the
movements are from P4 to P3 to P0.
Movements from P0 to P1 to P2 to P3 to P0
are all executed with relative position data.
While moving from P2 to P3, stop with a
deceleration stop and move to P4 in a direct
operation.
When memory operation is re-started, the
movements are from P4 to P3’ to P0’.

Direct Operation Timing Charts
This section provides timing charts showing ABSOLUTE MOVEMENT com-
mand and RELATIVE MOVEMENT command execution. The X axis is used as
an example.
