Product Overview: Nidec Control Techniques M701-08201320A
The M701-08201320A is a flagship high-performance AC variable speed drive from the Unidrive M701 series. Specifically engineered for 200V industrial networks, this Frame 8 drive provides a massive continuous output current of 132 Amperes. The M701 series is designed as the ultimate upgrade path for the legacy Unidrive SP, featuring an onboard RS485 interface for seamless integration into existing MODBUS RTU networks while delivering cutting-edge motor control for induction, permanent magnet, and high-dynamic servo motors.
Advanced Motor Control and Machine Logic
The M701-08201320A utilizes Nidec’s most sophisticated algorithms, including RFC-A (Rotor Flux Control for induction) and RFC-S (for servo motors). This allows for ultra-precise speed and torque regulation even in the most demanding applications like industrial test stands, heavy-duty cranes, and large-scale extruders. With an onboard PLC based on CODESYS, the M701 can handle complex decentralized logic, reducing system latency by processing motion tasks directly on the drive hardware.
