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
