 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 time

aligned feed-forward and other proprietary techniques with

 loop closure rates up to 20 kHz. 

The Ndrive family includes several versions of low noise,

 ultra-high-performance linear drives. The Ndrive series

 provides high bandwidth and superb linearity required for

 the ultimate in velocity regulation as well as positional

 stability. The HLe offers the ability to use resolver or

 inductosyn sensors and provides the highest level of

 encoder interpolation. The Ndrive CL is available for

 applications requiring low noise and is optimized for cost

 sensitive, lower-power applications. For low-power, high

 precision systems use the Ndrive ML.

 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 HLe 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
