Frequently asked questions

Will the MR-J4-70B-RJ drop into a panel specified around the FX5-80SSC-S?

No. The FX5-80SSC-S is a MELSEC iQ-F simple motion module — a PLC-based motion controller that occupies a PLC rack slot and weighs 0.3 kg. The MR-J4-70B-RJ is a standalone servo amplifier with its own power stage and enclosure. They serve different roles in the control chain: the FX5-80SSC-S sends command pulses; the MR-J4-70B-RJ amplifies them to drive a motor. Rewiring and a different panel layout are required.
