42 L-type Integrated Motor (RS485)

Product Overview

This series of integrated stepper motor drivers adopts the new generation 32-bit DSP technology, combined with RS485 bus control functionality, supporting the MODBUS-RTU communication protocol. It can connect up to 32 axes, enabling multi-axis bus synchronous control. The driver features 15 internal position segments and 15 internal speed segments, supports automatic homing, absolute/relative positioning, JOG functions, and can be directly controlled using a touchscreen or a controller with an RS485 interface.

Features

Voltage input range: DC18V to 36V Drive current: 2.8A Communication interface: RS485 Communication protocol: Modbus RTU Baud rate: 9600, 19200, 38400, 115200 (set via DIP switch SW5) Features protection functions such as overvoltage, overcurrent, undervoltage, and position deviation [closed-loop]

DIP Switch Settings

This series of 485 bus integrated machines has 6-position DIP switches, which can be used to set the 485 station number, communication baud rate, and terminal resistor, distributed as shown in the figure below:

Baud Rate Setting

Baud Rate	SW5
115200	OFF
Custom	ON

When SW5 is ON, the baud rate can be modified through PA-28 (decimal address 40), 0:115200; 1:38400; 2:19200; 3:9600

Terminal Resistor Setting: When SW6 is set to ON, a 120Ω terminal resistor will be connected between the signal lines to prevent signal reflection at the cable end when nodes send signals on the network.

Driver Station Number Setting

Station Number	SW1	SW2	SW3	SW4
