Introduction Ensemble HLe
Chapter 1: Introduction
Aerotech’s Ensemble HLe network digital drive is a high performance linear amplifier designed to eliminate
the nonlinearities common with PWMamplifiers. The drive provides deterministic behavior, auto-
identification, and easy software setup. The Ensemble HLe’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 Ensemble HLe is offered with an optional encoder interpolation feature (-MXH), an auxiliary square wave
encoder input for dual loop control, dedicated analog and digital I/O (expandable with the -IO option), a
resolver input (-RDP option), and separate power connections for motor and control supply voltages.
