The Panasonic A4 Family Servo Motor (Model: MSMA102S1G) is a low-inertia type servo motor designed for high-performance motion control applications. It features a speed response frequency of up to 1 kHz, enabling rapid and precise response to command changes.

Equipped with an instantaneous speed observer, the motor can detect rotational speed quickly and with high resolution, enhancing control accuracy. Its advanced mechanical adaptability allows it to perform optimally across a wide range of mechanical systems—from vibration-prone conveyor belt drives to high-rigidity ball screw mechanisms—thanks to an automatic tuning function.

The motor includes two built-in adaptive notch filters. The adaptive filter automatically adjusts its notch frequency to match the mechanical resonance frequency, effectively suppressing noise caused by mechanical instability or resonance frequency variations. In addition, two independent notch filter channels are provided, each allowing separate adjustment of notch frequency and depth in 1 Hz increments.

The motor delivers a rated output of 1.0 kW and operates on a 200V power supply. It uses a 17-bit incremental/absolute universal rotary encoder with a 7-wire interface. This standard design model features a keyed shaft, no brake, and an oil seal for improved durability. It is ready for direct use in compatible systems.
