Aerotech announce the launch of the NµDrive - a competitively priced, high performance digital servo amplifier with IEE 1394 Firewire® interface; designed for use with its A3200 Digital Automation Platform for extremely cost effective multi-axis motion control applications.
With a peak output of 10A at 80 VDC and continuous rating of 5A, the NµDrive features a DSP controlled PWM amplifier stage with current, position and velocity sampling rates of up to 20 kHz for excellent positioning performance and speed stability. NµDrive has dual Firewire ports for easy networking of multiple drives, each receiving real-time position and velocity update information from the A3200. Available for use with a wide range of Aerotech standard rotary, direct-drive rotary and linear brushless servomotors, the NµDrive drive can also be configured for use with DC brushed and with stepper motors.
As standard, the NµDrive includes an encoder interface, dedicated end of travel limit switches, hall-effect sensor inputs and an emergency stop input. Control options include an 8 input, 8 output user-defined I/O expansion board with screw terminal connection, plus a 16-bit analogue input, an 18-bit analogue output and a relay output, suitable for a brake. Further options include a programmable encoder multiplier for up to x1024 quadrature output.
An externally mounted, finned heat-sink is available for higher power applications and provision is made to include a 40W shunt resistor. The NµDrive requires an external power supply (60 to 80 VDC at 10A) which is available from Aerotech and an option is available for a separate auxiliary logic supply input which may be used for "Keep Alive" use.
The ultra-compact size of the NµDrive at just 158 mm high x 42 mm wide and 118 mm deep will allow several units to be housed in a relatively small machine control cabinet or individual NµDrives can be conveniently distributed on the machine, close to the corresponding motor allowing only minimal wiring of the DC voltage from a power supply and the Firewire connection to the A3200 network.
Aerotechs A3200 Digital Automation Platform is a powerful, software only machine control system combining a high-performance, 32 axis motion engine and other machine control function modules such as HMI and soft PLC for a completely integrated solution with decentralised drives interfaced via its Firewire interface. The NµDrive joins a family of Aerotech digital servo amplifiers with peak ratings up to 100A and DC bus voltages to 320 VDC in PWM and Linear drive-stage designs. Single packaged drives with direct-on-line power supply or multi axis rack mounted drives may be mixed to suit specific requirements and additional features available include dual encoder inputs, USB and 10/100 Base-T Ethernet ports for I/O modules.
The A3200 Digital Automation Platform is used in applications ranging from semiconductor, data storage, laser processing, automotive, and machine tool industries and includes a wide range of advanced motion control features and commands aimed at increasing and improving product quality and throughput performance. The NµDrive will help reduce the overall cost of such applications and will be of particular interest to machine builders and manufacturers of medium power automated machinery such as packaging and processing equipment.
Aerotech design and manufacture mechanical position systems and associated control and drive products for a very wide range of production, test and research applications All Aerotech systems are supplied complete with motor power and encoder cables, performance and calibration related documents and a CD with complete interconnection drawings to help integrators with their own system documentation. In addition, all motor parameter set-up data for the software configuration file is included; with full technical support and product training always on hand, system commissioning is straightforward requiring little more than connecting cables and applying power before programming application software. These features are built into every Aerotech product ensuring that the true cost of ownership is extremely competitive.
