The Ndrive^® family of digital servo amplifiers are high performance discrete drives used with the Automation 3200 motion controller. These drives are capable of controlling brushless, DC brush, and stepper motors over a wide range of operating voltages and currents. Based on a common architecture, Ndrive amplifiers perform both current- and position-loop closures digitally.

The use of high-performance double-precision processors allows these drives to generate ultra-smooth motion profiles. Servo system response is optimized with the use of up to eight second-order loop-shaping filters, precise timealigned feed-forward and other proprietary techniques with loop closure rates up to 20 kHz.

The Ndrive family is offered in a number of highly efficient PWM versions. The Ndrive MP is a low power, small footprint PWM drive ideal for space-sensitive applications. The Ndrive CP is a medium-power PWM drive capable of running directly from AC mains voltage and is optimized for cost-sensitive applications. The Ndrive HPe is the highest performance PWM drive providing a host of features not available on the other PWM drives, and is available in output current ranges from 10 A to 150 A peak.

Options for the Ndrive family include integral encoder interpolation, one- to three-axis position synchronized output (PSO), automatic brake control, digital and analog I/O expansion, absolute encoder interface, and one- or two-channel resolver interfaces. An optional dedicated ethernet port is available on the HPe drives for connection to third-party I/O expansion devices. This provides the potential to connect to a large number of I/O points typically required for PLC-type applications.

Any combination of Ndrive amplifiers may be connected to the Automation 3200 FireWire^® network, allowing the system to be customized as needed.
