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 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. |
