Ndrive FCL Hardware Manual
Introduction
Chapter 1: Introduction
Aerotech’s Ndrive FCL (Fast Linear Servo) network digital drive is a high-performance linear amplifier
designed to eliminate the non-linearities common with PWM amplifiers. The drive provides deterministic
behavior, auto-identification, and easy software setup. The Ndrive FCL’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 FCL has an encoder interpolation feature, dedicated analog and digital I/O, and separate power
connections for motor and control supply voltages
