Product details

Mitsubishi MR-J4-350B is a 1-axis servo amplifier from the J4 series, rated 17.0 A continuous output to drive a motor on 3-phase 170 VAC. Main circuit supply is 3-phase 200-240 VAC, 50/60 Hz, with allowable fluctuations of single-phase 170-264 VAC for the control section. Control method uses sinusoidal wave PWM with a current control system, giving smooth torque down to low speeds. Power consumption is 30 W, so panel thermal analysis should account for that heat load. Control power comes from a dedicated DC 24 V ± 10 % supply drawing 0.3 A (including the CN8 connector signal). That supply is separate from the main power bus.

Integration notes

Main circuit supply: 3-phase 200 VAC to 240 VAC, 50/60 Hz. Motor output: 3-phase 170 VAC. Control power on CN8: DC24 V ± 10%, 0.3 A.
