The company's DM805-AI Leadshine Technology Co., Ltd.  is a stepper motor driver with built-in oscillator based on the latest digital control algorithm. It brings a unique level of smoothness of movement, ensures optimal torque and eliminates mid-range instability. The technology of motor self-testing and automatic parameter setting offers optimal performance of various stepper motors. Thus, stepper motors work with less noise, less heating and smoother movement.

With a wide input voltage range of 20 ~ 80 VDC and a maximum current of 5.0 A RMS, it is compatible with two-phase stepper motors from Nema 17 and up to Nema 34.

Three built-in potentiometers are used to preset and adjust speed, acceleration and deceleration. In mode 0-5 V speed mode the motor speed is controllable and follows the analog input 0-5 V. In mode Low/HIGH speed mode motor speed is selected by digital input and adjusted by high/low speed potentiometers. In mode position mode the DM805-AI works as a traditional stepper motor driver with pulse and direction inputs. There is a 5V power supply in the driver, so we don't need an additional external power supply for input/output signals.

An example of using the DM805-AI stepper motor driver can be seen in the blog post: Stepper Motor Control with Leadshine DM805-AI

Specifications and instructions for use

DM805-AI User Manual

DM805-AI enables computer configuration and current settings, anti-resonance tuning via RS232 communication. However, the DM805-AI can function quite properly without it. The DM805-AI is fully configurable with switches on the chassis.
