DM805-AI Digital Stepper Drive With Analogue Input

DM805-AI Digital Stepper Drive With Analogue Input

(80VDC input, 5.0A)

Motion Control Products Ltd's digital stepper drive DM805-AI is a digital stepper drive with built-in oscillator, featured in supporting 0-5V analogue signal for speed controls. Using the latest digital control algorithm, it brings a unique level of system smoothness, providing optimum torque and nulls mid-range instability. The self-test and auto-configuration technology offers optimum responses with different motors and easy-to-use. The driven motors can run with much smaller noise, lower heating, smoother movement than most of the drivers on the markets.

The three built-in potentiometers are used to pre-set and adjust the velocity, acceleration and deceleration. In 0-5V speed mode, the motor speed is controllable and follows the analogue 0-5V input. In high/low speed mode, the motor speed is selected by digital input and adjusted by the high/low speed potentiometers. The user can run the motor with the least configuration and connection. In position mode, the DM805-AI digital stepper drive can be used as a traditional stepper drive. There is a 5V power supply output for customer’s use.

Features

Applications

DM805-AI stepper drive is suitable for the application which needs to adjust the velocity via the potentiometer or analogue 0-5V command. It can work with the size NEMA 17/23/34 stepper motors to replace the brushless motor with gearbox, due to the nature of its high torque and less motor noise at low speed. It can be used in various kinds of machines, such as rotary heat exchange, conveyor belts, transport vehicle, laser cutters, laser markers, high precision X-Y tables, labeling machines and so on.
