The Mitsubishi MRH100BN is an AC servo drive that adheres to the SSC-NET communication standard. This device requires a 3-phase power supply of 200-230V AC at 50 or 60 Hz. Its rated power output reaches 1 kilowatt. A built-in dynamic brake is included to enhance performance during operational shifts. This servo drive utilizes sine-wave PWM and current control for efficient motor operation.

Speed accuracy is highlighted by a frequency response of 250 Hz or more. The MRH100BN is designed with protective features such as overcurrent and overvoltage safeguards, overload detection, motor overheating protection, and encoder fault detection, ensuring reliability and safety during operation. When integrated with an absolute position encoder, it supports absolute positioning capabilities, increasing precision in motion control.

Operating conditions are specified within non-freezing temperatures from 0 to +55°C, while storage conditions can range between -20°C and +65°C. This servo drive can withstand humidity levels of up to 90% relative humidity without the risk of condensation, enabling it to function effectively in various environments. Additionally, it shows resilience against vibrations, rated at 5.9 m/s² (0.6G).

The MRH100BN features an open cooling system (IP00) and weights 2.4 kg (5.29 lbs), contributing to its lightweight design. It uses an RS-232C communication interface, allowing for parameter settings, status monitoring, and operational indications, facilitating user interactions and control configurations.
