CL2-57C Closed-Loop 17-bit Absolute Stepper Driver

CL2-57C Closed-Loop 17-bit Absolute Stepper Driver

Product Overview

The CL2-57C two-phase closed-loop stepper driver is a stepper drive product developed using the latest-generation 32-bit DSP chip, combined with our company’s many years of expertise in motion control. It supports both 17-bit and 23-bit encoders and offers three control interfaces: pulse‑type, RS485 bus, and CANopen bus. This particular model is a CANopen‑based closed-loop stepper driver.

Features

Voltage input range: DC24V~50V Maximum peak current: 7A Compatible motor flanges: 42/57/60 DI input current: 10–50mA DI input voltage: DC24V Communication interface: CANopen Equipped with protection functions for overcurrent, overvoltage, and position deviation.

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
Err7	Encoder ROM motor information missing	Flashes 7 times	Check whether the encoder ROM correctly stores motor-related parameters.	Power-down reset
Err8	Absolute Encoder Battery Warning	Flashes 8 times	Check whether the encoder battery voltage is normal.	Power-down reset
Err9	Absolute encoder battery failure	Flashes 9 times	Encoder battery discharged; after replacing the battery, reset P0D.07.	Power-down reset
Err10	Encoder Communication Alarm	Flashes 10 times	Check whether the encoder cable is disconnected.	Power-down reset
