Chapter 1: Safety Information

In order to achieve the optimum, safe operation of the Violin servo amplifier, it is
imperative that you implement the safety procedures included in this user guide. This
information is provided to protect you and to keep your work area safe when operating
the Violin and accompanying equipment. Read this chapter carefully before you begin
the installation process.

Ensure that all system components are connected to earth ground. Electrical safety is
provided through a low-resistance earth connection.

Only qualified personnel may install, adjust, maintain and repair the servo amplifier. A
“qualified person” has the knowledge and authorization to perform tasks such as
transporting, assembling, installing, commissioning and operating motors.

The Violin servo amplifier contains electrostatic-sensitive components that can be
damaged if handled incorrectly. To prevent any electrostatic damage, avoid contact with
highly insulating materials, such as plastic film and synthetic fabrics. Place the product
on a conductive surface and ground yourself in order to discharge any possible static
electricity build-up.

1-1

To avoid any potential hazards that may cause severe personal injury or damage to the
product during operation, keep all covers and cabinet doors shut.

The following safety symbols are used in this manual:

Warning:

This information is needed to avoid a safety hazard, which might cause
bodily injury.

Caution:

This information is necessary for preventing damage to the product or to
other equipment.

Note:

This is auxiliary information that ensures the correct operation of the
equipment.

1.1 Warnings

Cleaning after soldering

To avoid the damage of the product's acrylic coating the Violin must not

be cleaned after soldering by dissolving solvents and /or "water"
cleaning process. For more details:

http://www.elmomc.com/applications/article/Soldering-and-

Cleaning_Application-Note.pdf

To avoid electric arcing and hazards to personnel and electrical contacts,
never connect/disconnect the servo amplifier while the power source is

on.

Power cables can carry a high voltage, even when the motor is not in
motion. Disconnect the Violin from all voltage sources before it is opened
for servicing.

After shutting off the power and removing the power source from your
equipment, wait at least 5 minutes before touching or disconnecting parts
of the equipment that are normally loaded with electrical charges (such as
capacitors or contacts). Measuring the electrical contact points with a
meter before touching the equipment is recommended.

1.2 Cautions

The Violin servo amplifier contains hot surfaces and electrically-charged
components during operation.

The maximum DC power supply connected to the instrument must comply
with the parameters outlined in this guide.

1.3 Conformance to Standards

The Violin servo amplifier has been developed, produced, tested and documented in
accordance with the relevant standards. Elmo Motion Control is not responsible for any
deviation from the configuration and installation described in this documentation.
Furthermore, Elmo is not responsible for the performance of new measurements or
ensuring that regulatory requirements are met.

The Violin servo amplifier is intended for incorporation in a machine or end product. The
actual end product must comply with all safety aspects of the relevant requirements of
the European Safety of Machinery Directive 89/392/EEC as amended, and with those of
the most recent versions of standards EN60204-1 and EN292-2 at the least.

1-3

According to Annex III of Article 13 of Council Directive 93/68/EEC, amending Council
Directive 73/23/EEC concerning electrical equipment designed for use within certain
voltage limits, the Violin meets the provisions outlined in Council Directive 73/23/EEC.
The party responsible for ensuring that the equipment meet the limits required by EMC
regulations is the manufacturer of the end product.

1.4 Warranty Information

The products covered in this manual are warranted to be free of defects in material and
workmanship and conform to the specifications stated either within this document or in
the product catalog description. All Elmo amplifiers are warranted for a period of 12
months from the time of installation, or 18 months from time of shipment, whichever
comes first. No other warranties, expressed or implied — and including a warranty of
merchantability and fitness for a particular purpose — extend beyond this warranty.

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.
