Buying MR-J2S-10B from Flexa Systems
Buy the Mitsubishi MR-J2S-10B MELSERVO-J2-Super servo drive brand new and in stock, with refurbished units available on request, or send yours to Flexa Systems for repair. This 100 W amplifier runs from a 220 VAC single-phase supply at 1.3 A, which makes it a fit for low-power axes such as compact positioning tables, indexers and small pick-and-place mechanisms. When replacing it, compare the rating plate on your existing unit for the same 100 W capacity and single-phase 220 VAC input. Also make sure the attached servo motor is sized for a 100 W MELSERVO-J2-Super amplifier, because the drive and motor capacities must agree.
Repair option: send in your faulty unit for component-level repair — $340.00 with free diagnostics, a 2-year warranty, and a 5–30 business day turnaround. Repair typically costs 40–70% of a new unit, saving you 30–60%. Learn more about our Mitsubishi repair and servo drive repair service.

MR-J2S-10B FAQ
What should I match before installing a replacement MR-J2S-10B?
Confirm that the connected servo motor and its feedback device match what the original drive was running, and check that the panel supplies 220 VAC single-phase. If the old drive still communicates, back up its parameters first so you can load your tuning and settings instead of rebuilding them.
Should I get a brand new or refurbished MR-J2S-10B?
Brand new units are in stock now, and refurbished units are available on request. Every unit is tested and carries a 2-year warranty, and a refurbished drive typically saves 30-60%. That saving makes refurbished a practical choice for spares on older MELSERVO-J2-Super machines.
