Chapter 1 - General description 

 
1 - INTRODUCTION 

 

CD1-k 

all-digital amplifiers with sinusoidal PWM control are servo amplifiers that provide the control of brushless 

AC motors with position sensor.  
 
The 

CD1-k

 amplifier is a stand-alone single-axis block including power supply unit and mains filters. It is available 

in both 230 VAC and 400/480 VAC mains operated voltages. 
 

CD1-k

 amplifiers are working via a bus with "

CANopen

" communication protocol.  

 
The amplifier parameter setting can be made either by means of: 

 the 

CANopen

 bus or  

 

the specific parameter setting software 

Visual Drive Setup

, via the serial port RS-232.
