Haydon Kerk Motion Solutions has released the DCM4826X stepper motor drive module. The DCM4826X is a bipolar 2 phase chopper drive package rated for a 12VDC to 48VDC input voltage, and a continuous output current rating of 2.6Arms (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 DCM4826X is suitable for multi-axis stepper motor applications because less overall mounting real-estate is required due to its small size. The mounting plate of the totally enclosed unit measures a 64x60mm (2.5x2.4in) with mounting hole center-to-center distances of 52x38mm (2.0x1.5in). respectively. Total thickness of the unit from the mounting plate is 34.4mm (1.4in).

Configuration of the DCM4826X is through the Haydon Kerk 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.
