Chapter 1: Safety Information

Warning:

Caution:

Piccolo Installation Guide

In order to operate the Piccolo servo drive safely, it is imperative that you implement the safety
procedures included in this installation guide. This information is provided to protect you and
to keep your work area safe when operating the Piccolo and accompanying equipment.

Please read this chapter carefully, before you begin the installation process.

Before you start, make sure 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 drive. A qualified
person has the knowledge and authorization to perform tasks such as transporting, assembling,
installing, commissioning and operating motors.

The Piccolo servo drive 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.

7

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:

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

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

Piccolo Installation Guide Safety Information

1.1. Warnings

• To avoid electric arcing and hazards to personnel and electrical contacts, never

connect/disconnect the servo drive while the power source is on.

• Disconnect the Piccolo from all voltage sources before it is opened for servicing.

• The Piccolo servo drive contains grounding conduits for electric current protection. Any

disruption to these conduits may cause the instrument to become hot (live) and dangerous.

• After shutting off the power and removing the power source from your equipment, wait at

least 1 minute before touching or disconnecting parts of the equipment that are normally
loaded with electrical charges (such as capacitors or contacts). It is recommended to
measure the electrical contact points with a meter before touching the equipment.

1.2. Cautions

• The Piccolo servo drive contains hot surfaces and electrically-charged components during

operation.

8

• The maximum DC power supply connected to the instrument must comply with the

parameters outlined in this guide.

• When connecting to Piccolo to an approved isolated 24 VDC auxiliary power supply,

connect it through a line that is separated from hazardous live voltages using reinforced or
double insulation in accordance with approved safety standards.

• Before switching on the Piccolo, verify that all safety precautions have been observed and

that the installation procedures in this manual have been followed.

• Do not clean any of the Piccolo drive's soldering with solvent cleaning fluids of pH greater

than 7 (8 to 14). The solvent corrodes the plastic cover causing cracks and eventual damage
to the drive's PCBs.

Elmo recommends using the cleaning fluid Vigon-EFM which is pH Neutral (7).

Piccolo Installation Guide Safety Information

1.3. Directives and Standards

The Piccolo conforms to the following industry safety standards:

Safety Standard Item

Approved IEC/EN 61800-5-1, Safety Adjustable speed electrical power drive systems

Recognized UL 508C Power Conversion Equipment

In compliance with UL 840 Insulation Coordination Including Clearances and

Creepage Distances for Electrical Equipment

9

In compliance with UL 60950-1
(formerly UL 1950)

Safety of Information Technology Equipment
Including Electrical Business Equipment

In compliance with EN 60204-1 Low Voltage Directive 73/23/EEC

The Piccolo servo drive 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.

1.4. CE Marking Conformance

The Piccolo servo drive 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 98/37/EC as amended, and with those of the most recent
versions of standards EN 60204-1 and EN 292-2 at the least.

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
Piccolo meets the provisions outlined in Council Directive 73/23/EEC. The party responsible for
ensuring that the equipment meets the limits required by EMC regulations is the manufacturer
of the end product.

1.5. 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 drives 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: Product Description

Piccolo Installation Guide

This installation guide describes the Piccolo servo drive and the steps for its wiring, installation
and power-up. Following these guidelines ensures optimal performance of the drive and the
system to which it is connected.

2.1. Drive Description

The Piccolo series of miniature servo amplifiers is designed for DC brushless motors and
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 Piccolo amplifier meets UL508c and the relevant CE regulations.

The Piccolo 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
enhanced performance.
