CL57-RX Bus Closed-Loop Stepper Driver
Product Overview
The CL57RX is a closed-loop stepper driver. This driver uses an RS485 interface and supports the standard Modbus-RTU protocol. Multi-axis motion control functions can be realized through a touchscreen or a controller with an RS485 communication interface. Users can control up to 31 drivers simultaneously. The driver has 8 internal position tables, supporting functions such as automatic internal position switching, return to zero, position triggering, and JOG.

Fault Handling
Fault Phenomenon | Problem Description | Solution |
Red light flashes once | Overcurrent | Driver overcurrent alarm, check if motor wires have issues, or disconnect motor wires and power only the driver. If fault persists, internal driver fault requires factory repair. |
Red light flashes four times | Phase loss |
|
Red light flashes twice | Overvoltage | Driver overvoltage alarm, check if input voltage is within power supply range. |
Red light flashes three times | Undervoltage | Driver undervoltage alarm, check if input voltage is within power supply range. |
Red light flashes eight times | EEPROM Fault | Driver Fault |
Main Application Areas
