Description

MR7A 2phase digital stepper motor driver is a highly cost-effective with the resolution based on the ARM chips. The design is based on advanced digital current control technology, and features high torque, low noise, and low vibration. The running current, microstep resolution and other parameters are switch selectable. MR7A can be matched for 86mm(Nema34) 2-phase stepper motors.

Features

•  Input voltage 18-110VDC/18-80VAC
•  Output current 2.4-7.2A (peak current)
• Subdivision setting 200-25000 step/r
•  Support pulse/direction control mode, and can receive differential and single-ended signal commands
•  Suitable for two-phase stepper motors 60 to 86mm
• Self-detection, over-current and over-voltage protection
