The Ndrive MP digital servo amplifier from Aerotech is the ultra-compact, high performance discrete drive option for the Automation 3200 motion system. According to the company's press release, it measures only 41 mm wude by 107 mm deep and is capable of driving brushless, DC servo and stepper motors. In addition, the amplifier can perform both current loop and servo loop closure to ensure high positioning performance and rate stability in a micro-sized package. Standard options include software-based encoder multiplication, brake relay, additional I/O and separate logic supply inputs for "keep-alive" operation during an E-Stop condition.
