Aerotech Launches Ultra-Compact Digital Servo Amplifiers That Connect Via FireWire

Pittsburgh, PA -- The Ndrive MP digital servo amplifier from Aerotech is a discrete drive option for the Automation 3200 motion system. 41 mm wide by 141 mm high by 107 mm deep, the Ndrive MP is capable of driving brushless, DC brush-type servomotors and stepper motors, and can perform both current loop and servo-loop closure to ensure positioning performance and rate stability in a "micro-sized" package.

Ndrive® MPs are built on high performance DSPs to allow them to perform complex calculations in real time. This processing capability allows Ndrive MPs to sample the digital current loop and servo loop at a rate of 20 kHz. These amplifiers also handle both digital and analog I/O and encoder multiplication, providing a wide range of capabilities in a very small package.

Standard options for the Ndrive MP include software-based encoder multiplication, brake relay, additional I/O, and separate logic supply inputs for "keep-alive" operation during an E-Stop condition. Any combination of Ndrive MP amplifiers can be used on the FireWire network to allow the user to customize the system as needed.

Features include an output current up to 10 A peak at 80 VDC and dDigital current, velocity, and position loops for improved motion stability. The Ndrive MP is also CE compliant and has integrated E-Stop sense input.
