Chapter 1 Introduction
The 7XX8 Series of Digital Servo Amplifiers are high
performance, DSP (Digital Signal Processor) controlled
amplifiers. They control AC brushless motors with full
sinusoidal commutation. AC models operate directly from
AC mains. DC models operate from DC power sources,
which directly rectify the line. All models have full
isolation between signal and power stages. No power
transformers are required.
Built using surface-mount technology, these amplifiers
offer a full complement of features for AC brushless motor
control. All models use industry standard
±10V analog control signals for torque or velocity
control. A two-signal digital input takes step-motor
command pulses for position control:
•
In either CW/CCW or PLS/DIR format, or
•
from quadrature encoder A/B signals.
Digital preset inputs can be used to initiate 16 predefined
velocity, torque or position indexes.
A three phase MOSFET bridge output stage delivers
power in four-quadrants for smooth and efficient
bidirectional acceleration and deceleration of motors.
Windows software is used to configure the various gain
and current limit settings and to customize the amplifiers
for a wide range of loads and applications. Settings are
held in nonvolatile flash memory. Communication with the
