6. Key Selection Parameters

Controlled Axes: Select 4-axis (FX5-40SSC-S) or 8-axis (FX5-80SSC-S) according to equipment requirements.

Communication Protocol: SSCNET III/H (S version) for existing Mitsubishi servo systems; CC-Link IE TSN (G version) for new network architecture.

Interpolation Requirement: SSC module is mandatory for 4-axis linear or 2-axis circular interpolation; FX5U CPU only supports built-in 2-axis linear interpolation.

Synchronous / Cam Function: Indispensable for equipment requiring complex motion trajectories such as food packaging and electronic assembly.

System Expandability: Each FX5U CPU can connect up to 4 SSC modules, max. 32 controlled axes.
