Motor Drive System

Used with rotary stepper motors or stepper motor-based linear actuation, Haydon Kerk Motion Solution’s DCM4826X 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. It can be configured for full step, half step, or microstep (1/4, 1/8, 1/16, 1/32, 1/64 step size) operation. Since less overall mounting real-estate is required due to its small size, the drive is ideal in multi-axis stepper motor applications. In multi-axis motion systems, the space savings becomes greater as more axes are required.  The mounting plate of the totally enclosed unit measures 64 x 60mm with mounting hole center-to-center distances of 52 x 38 mm respectively.  Total thickness of the unit from the mounting plate is 34.4mm. Integration into a motion system is easy. Configuration of the unit is achieved through the company’s PDE user interface via an RS-485 protocol or a computer USB port.  Through the interface, the desired values for run current, hold current, delay time, and step size can be set.  Once the parameters are programmed, the drive can then accept the pulse, direction, and enable signals from the controller/indexer.  The pulse, direction, and enable signals are optically coupled into the drive, providing electrical isolation between the signal and power circuits.
