DC-powered servo alternative to ac drives

ViX intelligent servo drive from the Compumotor division of Parker Hannifin (Rohnert Park, CA) incorporates a flexible controller and 250/500 W output stage in an ultra-compact, 4.9 x 1.65 x 3.35-in. case. The all-digital, dc-powered design makes it less expensive than comparable ac drives, according to Compumotor.

ViX intelligent servo drive from the Compumotor division of Parker Hannifin (Rohnert Park, CA) incorporates a flexible controller and 250/500 W output stage in an ultra-compact, 4.9 x 1.65 x 3.35-in. case. The all-digital, dc-powered design makes it less expensive than comparable ac drives, according to Compumotor. ViX drive can serve in high-dynamic, multi-axis applications without needing individual power supplies, or it can be used as a standalone drive/controller in distributed controls.

ViX comes with outputs of 2.5 and 5 A rms continuous. Each version is able to handle motor bus voltages up to 80 V dc. The power stage has full PWM control with sinusoidal commutation. Resolver or encoder feedback is user selectable. RS-232C interface is standard, while a fieldbus module provides CANopen and RS-485. Standard I/O count includes five digital inputs and three digital outputs.
