4A Intelligent Step Motor Drive

The DCB-264 motor drive system integrates a powerful microstepping drive and high-performance programmable indexer with multiple user I/O ports to operate low-inductance step motors from a single supply voltage. Using a bipolar chopper drive circuit with a 20 kHz chopping rate, its voltage range is 24Vdc to 40Vdc and the output current is up to 4A per phase. Programmable hold current prevents excessive motor heating.
