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
