The MR-J3 has raised the bar for servo speed and performance. With a capacity range of 50W to 55kW, we reduced the size of both the amplifier and motor, added a high resolution encoder and advanced auto-tuning and vibration control. The J3's high torque motor can operate at up to 6000 rpm, and with a speed frequency response of 900 Hz. Twenty percent smaller than its predecessor, the J3's high resolution 262,144ppr encoder is mounted as a standard to provide stability even at low speeds. Mitsubishi Electric Automation's original model adaptive control and ever-evolving automatic tuning function makes precise tuning easy and the J3's advanced vibration control suppresses vibrations automatically. Set-up, diagnostics, and tuning are easy, thanks to MR-Configurator, a Windowsâ„¢-based software package. MR-Configurator has many improved diagnostic functions, such as an advanced machine analyzer, software oscilloscope, and high speed monitor. A parameter setting window makes start-up easy, and a USB interface enables high-speed sampling and long-term wavelength measurement. The MR-J3 supports the following control methods: Position, Speed, Torque, SSCNET Network, CC-Link and RS-485 Multi Drop.
