Servo amplifier powers digital
automation platform
Digital servo amplifier processes high-speed IEEE1394 FireWire delivered motion commands with 20kHz servo loop closure rates for current, velocity and position.
Aerotech's Ndrive is a DSP based high-performance digital servo amplifier that provides the power for A3200 distributed control applications by processing high-speed IEEE1394 FireWire delivered motion commands with 20kHz servo loop closure rates for current, velocity and position Easily configured for linear and rotary brushless servo motors, brushed DC motors and stepper motors, this versatile drive also handles encoder or resolver feedback and digital/analogue I/O with some models benefiting from a 10/100 Ethernet port for third party devices and PLCs

The ultimate high performance rotary motors!
Aerotech's latest BMS range of brushless servo motors use a novel slotless stator design to unsurpassed velocity control with zero cogging.
A wide range of CE approved models with peak current ratings from 10 to 100A at up to 320V DC are offered with a choice of single or three phase online AC power supplies.
DC power versions are also available; this is particularly cost effective for multi-axis setups.
A compact packaged model is also available for space-restricted applications.
Standard Ndrive options include onboard encoder multiplication for increased high-resolution applications, a three-axis position synchronised output (PSO) for precise on-the-fly laser firing, brake relay output, absolute encoder interface, and separate logic supply inputs for "keep-alive" operation.
Aerotech's A3200 digital automation platform is a software-based machine and motion control system for Windows based PCs that requires no additional hardware.
The A3200's fully deterministic FireWire network includes optional "soft" machine control modules with comprehensive controls for HMI, PLC and Vision Systems providing a completely integrated solution for up to 32 motion axes - with an expansion capability to 64 axes.
Programming and software development tools for the Automation 3200 include native RS274 G-code with an optional software development kit used to program the unit with Windows ActiveX components as well as C, C++, VisualBasic and LabView.
Firewire data transfer rates are up to 3.2Gbit/s over optical fibre - more than 30 to 1000 times faster than competing motion networks.
The nonproprietary architecture is available on standard PCs so upgrade and future proofing is guaranteed.
A3200 systems maintain a consistent performance with no system degradation as the number of axes increase.
The comprehensive list of motion control commands available range from simple point-to-point and interpolated moves to velocity and cubic spline profiling, electronic gearbox, fast position capture and high-speed registration moves. Request a free brochure from Aerotech ...
