Cymbal Installation Guide Introduction
MAN-CYMIG (Ver. 1.1)
2-1
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.
