The KD7909 dual‑axis synchronous controller manual provides setup, operation, and parameter adjustment instructions.
The KD7909 electric dual‑axis synchronous controller uses a microcontroller as the main control unit and provides two adjustable drive outputs plus a power‑voltage control signal. It can start and stop two motors synchronously, supporting single‑power‑on and sequential dual‑start processes, and allows digital adjustment and display of ten process programs such as start, brake, speed control, stop, protection, and delay.
The controller is built with a low‑power WE7909 chip (15 W total consumption), I²C bus, and digital display, resulting in a compact size (36.5 × 13.6 × 25 cm, 5.2 kg) and easy debugging, maintenance, and servicing. This manual is written in Chinese.
