Supporting a fully closed loop control system *1 as standard, MR-J4-GF/MR-J4-B/MR-J4-A servo amplifiers enable further precise positioning *2 . Supporting Fully Closed Loop Control *1. MR-J4-GF/MR-J4-B/MR-J4-A servo amplifier is compatible with two-wire type serial linear encoders. For four-wire type serial and pulse train interface (A/B/Z-phase differential output type) linear encoders, use MR-J4-GF-RJ/ MR-J4-B-RJ/MR-J4-A-RJ. *2. Some models do not support a fully closed loop control system. Refer to "Product lines" on p. 39 in this catalog.
