The three-phase AC170 V supply is the power stage voltage; the amplifier also accepts single-phase AC200 V to 240 V, 50/60 Hz for the control circuit, so you can feed it from a standard single-phase line for the logic while the motor power comes from a three-phase source. The built-in dynamic brake means you do not need an external braking resistor for moderate deceleration profiles, though vertical loads or high-inertia applications may still require one. ## Safety and protective features The MR-J4-500A includes a Safe Torque Off (STO) function per IEC/EN 61800-5-2, with a response time of 8 ms or less from STO input off to energy cut-off. The STO input accepts test pulses at 1 Hz to 25 Hz with an off-time up to 1 ms, which is compatible with most safety PLCs or safety relay outputs. Diagnostic coverage is rated medium at 97.6%. The protective functions list covers over-current, regenerative overvoltage, overload, servo motor overheating, encoder error, undervoltage, instantaneous power failure, overspeed, and excessive error — essentially all the common fault conditions you would expect in a servo drive. ## Control and communication Control is via sinusoidal wave PWM with a current control system. The command interface is a general-purpose interface, meaning it accepts analog speed and torque commands as well as pulse-train positioning. Speed control range is 1:2000 for analog speed command and 1:5000 for internal speed command. Speed variation is ±0.01% or less under load variation 0% to 100%, and ±0.2% or less with power fluctuation ±10% at 25 °C ambient. Torque limit can be set via parameter or external analog input of DC0 V to +10 V. Communication is via USB for PC connection (MR Configurator2 compatible) and RS-422/RS-485 for up to 32 axes on a single network. Two analog monitor channels are available.","metaTitle":"Mitsubishi MR-J4-500A MELSERVO-J4 Servo Amplifier, 5 kW","metaDescription":"Mitsubishi MR-J4-500A MELSERVO-J4 servo amplifier, 5 kW rated output, three-phase AC170 V, STO safety, active production.
