SMD have introduced their new Stepper Motor Controllers:

• SMSD-4.2Modbus and SMSD-8.0Modbus

• These are programmable stepper motor controllers with extended functionality.

• The devices can be controlled from a PLC using the Modbus RTU/ASCII protocol, and also work autonomously according to a user program.

• They provide microstepping 1/1 to 1/256.

• The morphing function provides a smooth transition from microstepping mode to full-step mode at a given speed, thereby maintaining torque at high speeds.

• Overheating protection is provided.

• The controllers are able to work in real-time and can be used both to build local automation units and distributed I/O systems with data exchange via RS-485 interface with Modbus protocol

Please just get in touch if you would like more detailed information or wish to view the manual!

SMSD-8.0Modbus

• Voltage: 12 – 48 VDC

• Max. current per phase: up to 8.0 A

• Microstepping: 1/1 – 1/256

• Control methods: programmable, potentiometer, STEP/DIR

• Interfaces: USB, RS-485 (Modbus ASCII/RTU)
