Simple Motion Module

CC-Link IE Field Network compatible Simple Motion module RD77GF QD77GF

SSCNET III/H compatible Simple Motion module

RD77MS QD77MS LD77MS FX5-_SSC-S

Select from two types of network: Ethernet-based open network (CC-Link IE Field Network) or optical network (SSCNET III/H).

The Simple Motion module is an intelligent function module which performs positioning control by following the instructions of PLC CPU. The positioning functions are used in the same manner as those of the Positioning module. Linear interpolation control and other controls can be achieved easily just by writing positioning data from sequence programs to the buffer memory. Positioning/synchronous/cam controls are performed with simple parameter setting and a start from a sequence program. Features of Simple Motion Module
