A networked digital drive available from Aerotech Inc. includes integral digital and analog input/output, support for square- and sine-wave encoders, a 100 Base-T Ethernet interface and a 400-Mb/s FireWire interface. The NDrive, which offers 80-MHz digital signal processing, has a hardware-based multiplier that provides 2048X interpolation and a software-based multiplier for up to 65,536X interpolation. The multipliers enable data rates in excess of 2 GHz, allowing systems with nanometer resolution to operate at speeds of meters per second. Pulse-width-modulated and linear versions are available as well as 10-, 20- and 30-A models. The position-synchronized output option can correlate an output signal to the vector displacement of up to three axes for applications such as laser firing and ultrasonic inspection.
