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

Multi-speed operation

1-speed positioning operation (excluding the deceleration stop) is continued several times by the table operation instruction.
(Page 26 1-speed positioning) At the last table, the operation decelerates and stops in the point that the speed can be
reduced.
The multi-speed positioning is performed when two or more 1-speed positionings are operated continuously by the continuous
operation of the DRVTBL/DRVMUL instruction. (Page 193 Continuous operation) Both relative address and absolute
address can be used for the 1-speed positionings. The figure shows an example of a 4-speed operation.
