Chapter 1: Safety Information
In order to achieve the optimum, safe operation of the Dragonfly and Butterfly servoamplifiers, 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 Dragonfly and Butterfly and accompanying equipment.
Please read this chapter carefully before you begin the installation process.
Before you start, ensure that all system components are connected to earth ground. Electrical safety is provided through a
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 Dragonfly and Butterfly servo drive contain
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.

1.1Warnings
Cleaning after soldering
To avoid the damage of the product's acrylic coating the Dragonfly/Butterfly must not be cleaned after soldering by dissolving solvents and /or "water" cleaning process. For more details:
To avoid electric arcing and hazards to personnel and electrical contacts, never connect/disconnect the servo drive while the power source is on.
Power cables can carry a high voltage, even when the motor is not in motion. Disconnect the Dragonfly and Butterfly from all voltage sources before they are opened for servicing.
The Dragonfly and Butterfly servo drive contain 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). Measuring the electrical contact points with a meter, before touching the equipment, is recommended.
1.2Cautions
The Dragonfly and Butterfly servo drives contain hot surfaces and
The maximum DC power supply connected to the instrument must comply with the parameters outlined in this guide.
When connecting the Dragonfly and Butterfly to an approved 12 ~ 95 VDC auxiliary power supply, connect them 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 Dragonfly and Butterfly, verify that all safety precautions have been observed and that the installation procedures in this manual have been followed.

The Dragonfly and Butterfly servo drives have 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.
1.4CE Mark Conformance
The Dragonfly and Butterfly servo drives are 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
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 Butterfly and Dragonfly meet 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.

Chapter 2: Introduction
This Installation Guide is intended for design engineers who are integrating Elmo Motion Control Cymbal servo amplifiers into a machine.
2.1Product Description
The Cymbal series of servo amplifiers is designed to operate in the current mode controlling
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
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.
