Mitsubishi's MR-J3-700BN is an advanced servo amplifier operating at 7 kilowatts. It is equipped to handle a 3-phase power supply, providing flexibility with rated voltages of 200 to 230 Volts AC. It is integrated with an SSCNET III/H interface, ensuring efficient communication with other system components.
This amplifier employs a combination of sine wave pulse width modulation (PWM) and current control methodologies for precise control. It can manage input frequencies from 50 to 60 Hertz while accommodating frequency fluctuations within ±5%. The operating environment should remain non-freezing, with temperatures between 0 and 55 °C, allowing the device to function reliably.
The MR-J3-700BN is equipped with external dynamic braking capabilities, which enhances its braking performance in dynamic applications. The interface power supply requires 24 Volts DC at a capacity of 150 milliamperes. Additionally, this servo amplifier has a capacitor charging capability of 70 joules and features a built-in regenerative resistor rated at 170 Watts.
When connecting the main circuit power supply, an inrush current of 88 Amperes is anticipated, while the control circuit power supply requires an inrush current of 30 Amperes. This unit exemplifies Mitsubishi's commitment to durability and precision in servo applications.
