The DCM4826X stepper motor drive module is a bipolar 2 phase chopper drive package rated for a 12-48VDC input voltage and a continuous output current rating of 2.6A rms (3.68A peak) per phase. The drive can be used with rotary stepper motors or stepper motor-based linear actuators and can be configured for full step, half step, or microstep (1/4, 1/8, 1/16, 1/32, 1/64 step size). The unit is ideal in multi-axis stepper motor applications because less overall mounting real-estate is required due to the small size of the drive. In multi-axis motion systems, the space savings becomes greater as more axes are required. The mounting plate of the totally enclosed unit measures a mere 64mm x 60mm (2.5-in x 2.4-in) with mounting hole center-to-center distances of 52mm x 38mm (2.0-in x 1.5-in) respectively. Total thickness of the unit from the mounting plate is 34.4mm (1.4-in). Through the interface, the desired values for Run Current, Hold Current, Delay Time and Step Size can be set. The pulse, direction and enable signals are optically coupled into the drive, providing electrical isolation between the signal and power circuits.
