The ZBE12A8 servo drive provides high performance at a low price in a small package. The ZBE12A8 is an analog drive that operates in encoder velocity mode. They are fully protected against over-voltage, over-current, over-heating and short-circuit. A single digital output indicates operating status. All models interface with digital controllers that have analog /-10V output. These servo amplifiers require only a single unregulated isolated DC power supply.
