MRH45KAN4

Mitsubishi's MRH45KAN4 general-purpose AC servo motor in the MELSERVO MR-H series provides versatile and strong performance across many applications. This motor features a rated output power of 45 kilowatts, ensuring reliable operation across various tasks. It operates at a power supply voltage of 400V AC (3-phase) and supports frequencies of 50/60 Hz.

Control is flexible, allowing for position, speed, torque, and switch-over modes. Speed commands can be input from 0 to ±10 VDC, enabling precise adjustments. The maximum input pulse frequency reaches 400 kpps through a differential receiver, while the position command pulse factor accommodates a range from 1/50 to 50 and supports electronic gear mechanisms. The torque command can also be input with values from 0 to ±8 VDC, enhancing versatility.

The speed control range is significant, with a ratio of 1:5000 available, though this reduces to 1:2000 when utilizing external analog speed settings. For safety, the MRH45KAN4 is equipped with an internal electronic thermal relay that protects against overload conditions. It operates within a temperature range from 0°C to +55°C, ensuring dependable functionality without freezing issues.

Communication functions via RS-232C allow for parameter setting, monitoring, and operational control. Additionally, absolute position detection is supported by an encoder and battery backup. The servo motor also includes protective features that safeguard against overcurrent, overvoltage, overload, overheating, undervoltage, and power failures, making the MRH45KAN4 a robust choice for diverse industrial applications.
