Variable Speed Operation - Mitsubishi Electric MELSEC iQ-F FX5 User Manual

Operation of the complete flags
The following describes the operation timings of the complete flags.
If dwell time is specified, the flag turns on after the dwell time elapses.
FX3 compatible (Effective only at TBL instruction or
DRVTBL instruction execution)
Instruction execution

condition
*1 The flag turns on only for one scan when the drive contact of the instruction turns from OFF to ON.
*2 Only high-speed pulse input/output module is supported.

Variable Speed Operation

The following explains control method [4: Variable Speed Operation].
Setting data
The following table shows the operand assignment.
Operand 1
Description None

Range
Details None
*1 Command speed can be changed during positioning operation. (Page 37)
*2 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.
Processing details
Operation with one table and operation of stepping operation are the same as that of the PLSV/DPLSV instruction. (Page
191 Stepping operation, Page 122 Variable Speed Operation) When this table is used, deceleration stop is performed by
turning off the drive contact of the table operation instruction. If dwell time is set, the complete flag turns on after the dwell time
elapses. (Page 77)
