Multi-Channel Stepper Motor Controller

Design Note #114

Multi-channel Stepper Motor Controller

This four channel micro-stepping motor controller board supplies precision motion control processing for a variety of precision operations. Applied as dual x-y motion tables or a single x – y – z motion system. Micro-stepping controllers supply precision drive, lock and breaking currents to a series of stepper motors.

STM32F415 ARM Cortex-M4 Processor

Powered by an STM32F415 microcontroller, this controller board performs complex floating point calculations significantly faster than similar Cortex-M3 devices. Single instruction floating point instructions improves motion algorithm performance and flexibility. Motion control development and execution is easier on such a platform. This motion controller includes the following features.

• Serial FRAM Memory

• USB 2.0 OTG Port Zoom

• Four Stepper Motor Channels

• Fast Ethernet Ports

• Four Quadrature Encoder Inputs

• Four Temperature Sensors

• USB 2.0 Host Ports

• CAN Bus Interfaces

• 24V Input Power

• UART, IIC, SPI, Ports
