CL57R-2A Two-Axis Bus Closed-Loop Driver

Product Overview

The CL57R-2A is a fully digital integrated closed-loop one-to-two stepper driver. This driver uses an RS485 interface and supports the standard Modbus-RTU protocol. It can achieve multi-axis motion control through a touchscreen or a controller with an RS485 communication interface. Users can simultaneously control up to 31 drivers. The driver has 8 internal position tables, supporting functions such as automatic internal position switching, homing, position triggering, and JOG.

Features

Voltage input range: DC 20V to 50V Maximum peak current: 5.6A 1000-line encoder Communication interface: RS485 Communication protocol: Modbus RTU Automatic motor parameter tuning function Protection functions including overvoltage, overcurrent, and position deviation alarms
