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.
