The Mitsubishi MR-JE-10A is a 100 W servo amplifier from the MELSERVO-JE series, designed for general-purpose motion control. It accepts 1-phase or 3-phase 200 VAC to 240 VAC input at 50/60 Hz and delivers a rated current of 1.1 A. The built-in dynamic brake means you don't need an external braking resistor for stopping the motor under normal deceleration — a real space saver in a crowded cabinet.
The 1.1 A rated current tells you the continuous output the amplifier can support at its 100 W rating. Match this to a servo motor whose rated current falls at or below 1.1 A — oversizing the motor will trip the drive on overload. The sine-wave PWM control method gives smooth torque at low speeds, which matters for positioning applications like pick-and-place or indexing conveyors. IP20 (open type) with natural cooling requires a clean, ventilated enclosure.
