Cymbal Installation Guide

Chapter 2: Introduction 
This Installation Guide is intended for design engineers who are integrating Elmo Motion 
Control Cymbal servo amplifiers into a machine.  
2.1 Product 
Description 
The Cymbal series of servo amplifiers is designed to operate in the current mode 
controlling permanent-magnet trapezoidal brushless motor and DC brush motor.  
The Cymbal exhibits “the highest density of power and intelligence” and can deliver up 
to 11.3 kW of continuous power or 13.6 k W of peak power in a most compact and 
efficient package.  
The Cymbal operates from a DC power source in the range of 12 ~ 195 VDC.  
The Power stage of the Cymbal is fully isolated from other sections of the Cymbal, such 
as the control stage and the heatsink. This contributes very significantly to the safety and 
the EMI immunity of the Cymbal. In addition it simplifies the requirements of the DC 
power supply used to power the DC bus of the Cymbal and allows also the operation 
with a non-isolated DC power source. 
The Cymbal incorporates full custom mixed analog/digital ICs and a hybrid power 
stage. The basic configuration is a current mode amplifier targeting the OEM market. As 
such, no trimmers are used in the basic version. In addition to its compliance with 
relevant MIL standards, the Cymbal amplifier also meets UL508c and the relevant CE 
regulations. 
The Cymbal power stage is implemented on ceramic substrates. This design enables very 
high thermal conductivity, high current carrying capacity, improved EMC and good 
mechanical strength. The control section is implemented by dedicated custom ICs that 
contribute to enhanced performance and reliability.
