The Keya MMT DC servo driver manual provides installation, configuration, and operation instructions with technical specifications and troubleshooting.
This manual describes the Keya MMT series DC servo driver, highlighting its PWM H‑bridge control, four‑quadrant operation, full isolation design, and various protection features. It outlines the driver’s suitability for a wide range of mechanical transmission equipment and details the required power inputs, signal interfaces, and motor selection guidelines.
The document also covers environmental requirements, wiring diagrams, panel adjustments, and fault analysis procedures, helping users set up the driver correctly, adjust parameters such as zero point, speed, and torque, and diagnose common error conditions. This manual is written in Chinese.

The driver accepts AC 40‑‑110 V for the 110 V series and AC 50‑‑220 V for the 220 V series as the main power supply.
Turn the ZERO knob until the motor remains locked when the control voltage is 0 V; this sets the zero speed reference.
The driver provides over‑voltage, over‑current, over‑temperature, output short‑circuit, motor over‑temperature, and feedback abnormality protections with alarm indicators.
