Chapter 1: Safety Information
In order to achieve the optimum, safe operation of the Saxophone servo amplifier, 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 Saxophone and its accompanying equipment. Read this chapter carefully
before you begin the installation process.
1.1 Amplifier Compliance
The end product used with the Saxophone must comply with the European Safety of
Machinery Directive 89/392/EEC safety requirements, and with the most recent versions
of the EN60204-1 and EN292-2 standards.
The Saxophone conforms to the following industry safety standards:
Item Safety Standard
Power conversion equipment Recognized UL508c
Insulation coordination, including clearance and
creepage distances of electrical equipment
In compliance with UL840
Safety of information technology equipment,
including electrical business equipment
In compliance with UL1950
Low Voltage Directive, 73/23/EEC In compliance with EN60204-1
1.2 Safety Precautions
Follow these safety guidelines when installing the Saxophone servo amplifier:
 Power connection during operations: Disconnect the Saxophone servo amplifier
from its power source during all operations, such as installation, adjustment
maintenance and repair.
 Qualified personnel: Ensure that only qualified personnel carry out any operation
relating to the Saxophone servo amplifier.
 Live servo operations: Perform operations when the amplifier is disconnected from
the power source. Only qualified personnel who are fully aware of the dangers of
performing operations connected to the power source should carry out these
operations.
 Components: Only certified Elmo representatives may replace damaged Saxophone
servo amplifier components.

1.3 Power Precautions
Observe the following safety precautions when connecting the Saxophone servo
amplifier to a power supply or during power-up.
 Power supply: The maximum AC/DC power supply connected to the instrument
must comply with the parameters outlined in this guide.
 Grounding: The Saxophone servo amplifier contains grounding conduits for electric
current protection. Any disruption to these conduits may cause the instrument to
become hot (live) and dangerous.
 Powering up: Before switching the Saxophone on, verify that all safety precautions
have been observed and that the installation procedures in this manual have been
followed.
The Saxophone SAX-xx/400 series is designed to operate only
from a 3-phase voltage source. The Saxophone SAX-xx/230
series is designed to operate from a 1- or 3-phase voltage
source. It can be connected directly to the line voltage. An
isolation transformer is not needed.

Chapter 2: Introduction
The Saxophone system includes the Saxophone servo amplifier and the Composer
software, which run in conjunction with your permanent-magnet synchronous motor.
The servo amplifier connects easily to your motor. You use the Composer software to set
the various servo and motor parameters that meet your specific configuration.
The Composer software is Windows-based and provides a plug-and-run tool that enables
users to quickly and simply set up the communication and the servo system. Refer to the
Composer Software Manual for more information.
This installation guide describes the Saxophone system and the steps for its setup,
installation and powering up. Following these guidelines ensures maximum functionality
of the Saxophone system.
2.1 System Description
The Saxophone system is designed for use with high-performance automated machinery.
The Saxophone series of servo amplifiers has been developed for permanent magnet
synchronous motors and incorporates digital velocity loop, a digital current loop and
sinusoidal commutation.
The Saxophone's basic configuration is a trimmerless velocity servo amplifier. All
adjustments to the velocity, current and commutation functions are made via the serial or
field bus (CANopen option) communication line, using a PC.
Independent control of the magnetic flux and the torque-generating current component
in motors is provided by sinusoidal control with phase advance algorithms. This is
particularly significant for permanent magnet synchronous motors and brushless motors
used in high-performance drives.
The Saxophone series' power source is a three-phase 400 VAC or one- or three-phase
230 VAC line. The control and auxiliary supplies are derived from a 24V AC or DC
supply that is isolated from the AC power bus. This allows a safe and economical "power
backup" feature that is essential for positioning systems.
The Saxophone series meets UL508C and the relevant CE regulations.

For three-phase supply voltage:
 The circuit breaker current rating should be between 150% to 200% of the amplifier
current.
 The circuit breaker voltage rating should be 460 VAC.
 The contactor should be up to 150% of the amplifier current.
For single-phase supply voltage:
 The circuit breaker current rating should be between 200% to 300% of the amplifier
current.
 The circuit breaker voltage rating should be 460 VAC.
 The contactor should be up to 200% of the amplifier current.
