The Leisai CL57D digital closed-loop stepper driver user manual provides specifications, wiring, settings, and troubleshooting instructions.
The CL57D is a digital closed‑loop stepper driver developed by Leisai for medium‑size automation equipment and CNC machines. It uses a 32‑bit DSP chip and offers high‑frequency pulse response, over‑current protection and easy upgrade from open‑loop stepper solutions.
The manual covers product overview, electrical and mechanical specifications, connector definitions, dip‑switch configuration, parameter programming via RS‑232, typical application wiring, encoder connections, and a detailed troubleshooting guide with LED fault codes. This manual is written in Chinese.
