32 TABLE OPERATION
32.2 Operations of Control Method
Interrupt 1 Speed Positioning
The following describes the control method [3: Interrupt 1 Speed Positioning].
The following table shows the operand assignment.
*1 The positioning address can be changed during positioning operation. (Page 371 Positioning address change during positioning
operation) However, only the last table accepts the change in the case of continuous operation.
*2 Command speed can be changed during positioning operation. (Page 372 Command speed change during positioning operation)
*3 When the positioning table data is set to use device, the value can be changed during positioning operation. The change is applied when
the table operation instruction is restarted.
*4 Set the number of output pulses per table execution (the total number of pulses before and after the interrupt) to 2147483647 or lower.
Operation with one table and operation of stepping operation are the same as that of the DVIT/DDVIT instruction. (Page
549 Stepping operation, Page 461 Interrupt 1-Speed Positioning) If dwell time is set, the complete flag turns on after the dwell
time elapses. (Page 417 Complete flag)
In addition, this table can be specified for continuous operation only for the CPU module. (Page 551 Continuous
operation)
Other than the following, the same as cautions for the DVIT/DDVIT instruction apply.
• Combinations other than the following cannot be used during continuous operation.
Control method [3: Interrupt 1 Speed Positioning] must be specified to the first or second table. If control method [3: Interrupt
1 Speed Positioning] is specified to the second table, only control method [5: Table Transition Variable Speed Operation] can
be specified to the first table.
• Continuous operation cannot be used for the high-speed pulse input/output module. If this table is specified for continuous
operation for the high-speed pulse input/output module, an error occurs.

in
pulse.
Set the speed within the range of
1 pps to 200 kpps in pulse.
For the FX5S CPU module, set a
value 1 pps to 100 kpps.
Dwell time is the time until the
complete flag turns on after the
positioning address is reached.
This is the count of inputs that are
necessary for interrupt. The
setting is enabled only in the
high-speed mode.
