Product description
The specified operating temperature range of the Mitsubishi Electric MR-J3-200A4 extends from 0 to 55 °C. Permissible humidity during operation and storage is up to 90 %, non-condensing. This digital AC servo amplifier belongs to the MELSERVO-J3 range and is assigned to the 400-V performance class with 2 kW. Its main power supply is 3-phase 380 to 480 V AC at 50 or 60 Hz; the permissible voltage range is 323 to 528 V AC. The control circuit also uses 1-phase 380 to 480 V AC. The interface power supply requires 24 V DC with a tolerance of ±10 % and a current capacity of up to 300 mA. Position, speed and torque control are implemented through sine-wave PWM and current control. In position control mode, the amplifier processes input pulses up to 1 Mpps through a differential receiver or up to 200 kpps with an open collector. Position feedback is specified at 262,144 pulses per motor revolution. For speed control, Mitsubishi specifies a range of 1:2000 with the analog speed command and 1:5000 with the internal speed command. A dynamic brake is built in. The enclosure is an open, fan-cooled design with IP00 protection. Its external dimensions are 90 mm wide, 168 mm high and 195 mm deep; net weight is 2.1 kg. These mechanical data support checking the available installation space. The complete MR-J3-200A4 type number distinguishes this version from other power and voltage classes within the MR-J3 series. For technical identification, the type number, performance class, supply, control modes, enclosure design and dimensions are therefore the decisive characteristics.
The item supplied will have the stated manufacturer or type number and the stated condition category. Serial number, manufacturing date, labels, colour, packaging and normal signs of use or storage may differ. Specifications
Unless expressly confirmed, technical information is provided to identify the device type. The complete manufacturer or type number is decisive.
