The MR-J2S-700B utilizes the SSCNET protocol, making it incompatible with the analog/pulse-train MR-J2S-700A variant. When replacing older MR-J2-700B units, ensure that the controller firmware supports the updated parameter set of the J2S series.
Because this unit is rated IP00, it must be installed in a clean, dust-free control cabinet (IP54 or better). In high-inertia applications, the internal regenerative resistor may overheat. If the amplifier frequently trips on regenerative overvoltage (AL.30) or regenerative overload (AL.37), an external regenerative option must be wired to terminals P and C, with the shorting bar between P and D removed.
Always use genuine Mitsubishi fiber optic cables for the CN1A/CN1B ports. Ensure the minimum bending radius of the fiber optic cable is strictly maintained to prevent signal attenuation, which leads to intermittent communication faults (AL.85). Ground the amplifier chassis directly to the main panel backplate using a short, thick braid to minimize high-frequency EMI.
Ensure all input power sources (main and control circuits) are completely de-energized before attempting installation, wiring, or maintenance. Wait at least 10 minutes after power-off for the internal bus capacitors to discharge. Verify that the charge lamp on the front face of the amplifier is completely extinguished before touching any terminals.
Mount the servo amplifier vertically on a flat, rigid surface inside the control panel, ensuring adequate clearance around the cooling fan intakes and exhaust ports.
Connect the protective earth (PE) terminal to the system ground before making any other electrical connections.
Wire the main 3-phase power supply to terminals L1, L2, and L3, and the control power supply to L11 and L21.
Connect the motor power cables to terminals U, V, and W, and plug the encoder cable into the CN2 port.
Insert the SSCNET fiber optic cables into CN1A and CN1B, ensuring they click securely into place.
