The Mitsubishi MR-JE-40B is a current-production servo amplifier from the MR-JE series, rated for 2.6 A output current on a 3-phase 170 VAC winding supply. It accepts a 3-phase or 1-phase 200 VAC input (170 to 264 VAC permissible), with a separate 24 VDC ±10% interface supply drawing 0.3 A. The control method is sine-wave PWM current control, and the amplifier communicates over SSCNET III/H at 0.444 ms or 0.888 ms cycle times.
Power and control wiring
Main power comes in on 3-phase or 1-phase 200 VAC, ±5% frequency tolerance. The amplifier rectifies this to a 170 VAC three-phase bus for the motor output. A separate 24 VDC control supply powers the logic and interface — watch the 0.3 A draw when sizing the panel's 24 VDC rail. The built-in dynamic brake handles deceleration energy without an external resistor for most load cycles; verify against your specific inertia ratio and decel profile.
