Processing details
When the interrupt input signal 2 is detected, the table in execution is switched to the next table as interrupt processing. Then,
the table following this table is operated. Until the interrupt input signal 2 is turned on, operation equivalent to the PLSV/
DPLSV instruction or control method [4: Variable Speed Operation] is performed. (Page 122 Variable Speed Operation,
Page 168 Variable Speed Operation)
If dwell time is set, the complete flag turns on after the dwell time elapses. (Page 77)
In addition, this table can be specified for continuous operation. (Page 193)
The following figure shows an example of an operation equivalent to interrupt 2-speed positioning combining control method
[5: Table Transition Variable Speed Operation] and control method [3: Interrupt 1 Speed Positioning].

Precautions
Other than the following, the operation is the same as that of the PLSV/DPLSV instruction.
• If control method [0: No Positioning] is set to the next table, deceleration stop is performed to end the table operation by
turning on the interrupt input signal 2. If control method [0: No Positioning] is set to the last table, the same operation is
performed.
• If the next table is for variable speed operation or interpolation operation, deceleration stop is performed to end the table
operation causing an error.
• When this table is used for stepping operation, the next table can be activated after a stop using the interrupt input signal 2
or pulse decelerate and stop command. If the pulse decelerate and stop command remains ON after stop, the table shift
command is disabled.
• Table control methods that can be used in combination during continuous operation are [5: Table Transition Variable Speed
Operation] and [3: Interrupt 1 Speed Positioning]. An error occurs if Interrupt 1 Speed Positioning is executed after Table
Transition Variable Speed Operation two or more times.
• If the command speed is changed to 0 during positioning operation, pulses are decelerated to a stop but the table operation
does not end. Thus, dwell time is not measured and tables are not switched. When the drive contact of the table operation
instruction is on, or changing to any value other than 0 the command speed restarts pulse output.
