Introduction Ndrive ML
Chapter 1: Introduction
Aerotech’s Ndrive ML (Ultra-Compact "Micro" Linear) network digital drive is a high performance linear
amplifier designed to eliminate the nonlinearities common with PWM amplifiers. The drive provides
deterministic behavior, auto-identification, and easy software setup. The Ndrive ML’s high performance
double precision floating point DSP controls the digital PID and current loops. All system configuration is
done using software-settable parameters, including control loop gains and system safety functions.
The Ndrive ML is offered with an optional encoder interpolation feature (-MXH or -MXU), an auxiliary square
wave encoder input for dual loop control, dedicated analog and digital I/O (expandable with the -IO option),
and separate power connections for motor and control supply voltages.
