The Leisai CL42 manual provides specifications, wiring diagrams, parameter settings, and troubleshooting for the digital closed‑loop stepper driver.
The CL42 is a digital closed‑loop stepper driver developed by Leisai, featuring a 32‑bit DSP controller, programmable current up to 3 A, and a pulse response up to 200 kHz. It supports 42‑series closed‑loop stepper motors and includes protection functions such as over‑current, over‑voltage, and tracking error detection.
The manual covers electrical and mechanical specifications, detailed interface definitions, DIP‑switch configuration, parameter adjustment via RS‑232, typical application wiring, and warranty information. It also explains LED status indicators and fault‑code handling for easy troubleshooting. This manual is written in Chinese.
