The CL57 V3.0 is a digital closed‑loop stepper driver developed by Leisai for industrial automation. It uses a 32‑bit DSP chip, supports 42/57/60 series closed‑loop stepper motors, and offers features such as adjustable current, high pulse frequency, and built‑in protection.
The manual covers electrical, mechanical and environmental specifications, detailed interface definitions, wiring diagrams, dip‑switch configuration, parameter settings via RS‑232, typical application examples, and warranty information. It also explains fault indication and troubleshooting procedures. This manual is written in Chinese.
| Continuous output current | 3 – 6 A |
|---|---|
| Input power voltage | +24 V to +48 V DC |
| Logic input current | 7 – 20 mA |
| Pulse frequency | 0 – 200 kHz |
| Insulation resistance | ≥ 100 MΩ |
| Weight | ≈ 280 g |
| Cooling method | Natural cooling or optional heat‑sink |
The red LED is a fault indicator; it flashes in a 5‑second cycle to show different fault codes.
Power the driver off and then on again; the fault is cleared after a power‑cycle.
Use dip switch SW5: OFF sets counter‑clockwise (CCW) rotation, ON sets clockwise (CW) rotation.
