If you're looking for big time stepper performance from a small driver, the MLA05641 is your answer. This powerful microstepping driver provides excellent torque in a compact and low profile encloser. The MLA05641 is also very easy to use. It features rugged terminal blocks, a rotary pot for current settings, and a visible silkscreen for easy installation and configuration. Versatile as well as powerful, the MLA05641 has a wide amperage range. It is designed to handle a minimum current of 1.0 Amp to a maximum current of 5.0 Amps per phase. It operates from a AC voltage of 95-250 Volts, making it a great fit for almost any stepper application. The MLA05641 features optically isolated inputs that are 3.5 - 24VDC compatible. The clock input can be set to receive either sinking or sourcing clock signals at frequencies up to 400KHz. The driver also features direction control, motor on/off capabilities, fault output and a built in short circuit and miswire shutdown protection. The MLA05641 is a bipolar type driver designed for use with 4, 6, or 8 lead stepper motors, making it compatible for series and parallel installations. The driver has a 12,800 steps per revolution or 0.028o per step resolution, with respect to a 1.8o stepper motor. It also has a motor current reduction feature that will help keep stepper motors cool at standstill, and LEDs that indicate power and pulses being received, and fault conditions.
