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 kW of peak power in a most compact and efficient package.
The Cymbal operates from a DC power source in the range from 12 to 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 UL 508C 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.
