CL286R-ABZ Two-Phase Closed-Loop Stepper Driver

CL286R-ABZ Two-Phase Closed-Loop Stepper Driver

Name: CL286R-ABZ Two-Phase Closed-Loop Stepper Driver
Brand: Shenzhen Lichuan Electric Co., Ltd.
Availability: InStock

Product Overview

The CL2 series stepper drives are developed using the latest-generation 32-bit DSP chip, combined with our company’s many years of expertise in motion control. They support 1000-line ABZ incremental encoders and offer three control interfaces: pulse‑type, RS485 bus, and CANopen bus. This particular model is an RS485‑based drive.

Features

Voltage input range: DC 30 V–110 V, AC 20 V–80 V Maximum peak current: 8 A Compatible motor flange size: 86 DI input current: 10–50 mA DI input voltage: DC 24 V Communication interface: RS‑485 Equipped with protection functions such as overcurrent, overvoltage, and position deviation alarms.

Troubleshooting

Fault code	Fault Information	ALM indicator light	Mitigation measures	Reset
Err1	Overcurrent or interphase short circuit	Flashes once	Check whether the load is excessive, whether there are any impacts, and whether the motor wiring is shorted.	Power-down reset
Err2	Power supply voltage is too high.	Flashes twice	Check the power supply operating range.	Automatic recovery
Err3	Power supply voltage too low	Flashes 3 times	Check the power supply operating range.	Automatic recovery
Err5	Motor out of tolerance	Flashes 5 times	Check whether the load is excessive and whether the encoder cable is loose.	Power loss, manual reset
Err6	485 Modbus error frame exists	Flashes 6 times	Verify that the 485/USB serial communication parameters are configured correctly.	Power-down reset

Main application areas

It is widely used in various precision automation applications, including 3C automation equipment, laser processing systems, engraving machines, dispensing machines, labeling machines, packaging machinery, small CNC devices, textile automation, medical devices, semiconductor testing equipment, vision inspection platforms, and logistics sorting systems.
