Chapter 2: Introduction
This user guide is intended for the design engineer who is integrating an Elmo Motion
Control Violin servo amplifier into a machine.
2.1 Product Description
The Violin series of miniature servo amplifiers for DC brush motors incorporates 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. The Violin amplifier meets UL508c and the relevant CE regulations.
The power stage is implemented on a single ceramic substrate. 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 higher and enhanced performance.
