parallel port stepper motor driver with micro-step

Integrated Stepper MotorDriver with Microstepping Features: Miniature Size 42.3mm*42.3mm*13.5mm NEMA 17 Frame Size could be mounted on NEMA 17, 23, 24 and 34 stepper motors. Integrally designed to fit onto motors seamlessly, as well as work standalone 10-40VDC supply, Max 2A/4A/8A adjustable output current, 1to16 Microstepping Dual H-bridge with PWM constant current control, Enable/shutdown controllable Opto-isolated inputs with common anode. Die-cast aluminium enclosure Stepper MotorDriver Overview UIM24002/24004/24008 stepper motor driversare a series of miniature, high performance stepper motor controller. They can be mounted onto NEMA17, 23, 34 and 42 stepper motors seamless through corresponding flanges. The thickness of thesestepper motor driveris less than 14mm, UIM 24002 is capable to provide 0.5-2A adjustable current. UIM 24004 is capable for 1.6-4A adjustable current output. UIM24008 is capable for 2A-8A.adjustable current output. Their mixed-decay current control reduces the back-EMF effect under high speed running condition and improves the performance. Except the UIM24002 takes 10-35VDC input, UIM240xx seriesstepper motor drivercan work with 12 to 40VDC input.. Enclosures of the UIM240xxstepper driverare made of die-cast aluminum which provide a rugged and durable protection and improve the heat dissipation.. Absolute Maximum Rating Supply Voltage 12 40VDC (10 35VDC for UIM24002) Current input at logic pins: +/- 30mA Storage Temperature -20 - +125 Operating Temperature -20 - +85 Note: Stresses beyond these listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
