Safety Considerations
Safety Precautions
This product is intended for professional incorporation into a complete system. If you install the product incorrectly, it may present a safety hazard. The product and system may use high voltages and currents, carry a high level of stored electrical energy, or are used to control mechanical equipment that can cause injury.
You should give close attention to the electrical installation and system design to avoid hazards either in normal operation or in the event of equipment malfunction. System design, installation, commissioning and maintenance must be carried out by personnel who have the necessary training and experience. Read and follow this safety information and instruction manual carefully.
Enclosure
This product is intended to be mounted in an enclosure that prevents access except by trained and authorized personnel and prevents the ingress of contamination. This product is designed for use in an environment classified as pollution degree 2 in accordance with IEC664-1. This means that only dry, non-conducting contamination is acceptable.
Setup, Commissioning and Maintenance
It is essential that you give careful consideration to changes to drive settings. Depending on the application, a change could have an impact on safety. You must take appropriate precautions against inadvertent changes or tampering. Restoring default parameters in certain applications may cause unpredictable or hazardous operation.
Safety of Machinery
Within the European Union all machinery in which this product is used must comply with Directive 89/392/EEC, Safety of Machinery.
The product has been designed and tested to a high standard, and failures are very unlikely. However the level of integrity offered by the product’s control function – for example stop/ start, forward/reverse and maximum speed – is not sufficient for use in safety-critical applications without additional independent channels of protection. All applications where malfunction could cause injury or loss of life must be subject to a risk assessment, and further protection must be provided where needed.
General warning
Failure to follow safe installation guidelines can cause death or serious injury. The voltages used in this unit can cause severe electric shock and/or burns, and could be lethal. Extreme care is necessary

at all times when working with or adjacent to this equipment. The installation must comply with all relevant safety legislation in the country of use.
AC supply isolation device
The AC supply must be removed from the drive using an approved isolation device or disconnect before any servicing work is performed, other than adjustments to the settings or parameters specified in the manual. The drive contains capacitors which remain charged to a potentially lethal voltage after the supply has been removed. Allow at least 6 minutes for the Epsilon 205, 3 minutes for Epsilon 202/203 and 30 seconds for E Series drives after removing the supply before carrying out any work which may involve contact with electrical connections to the drive.
Products connected by plug and socket
A special hazard may exist where the drive is incorporated into a product which is connected to the AC supply by a plug and socket. When unplugged, the pins of the plug may be connected to the drive input, which is only separated from the charge stored in the bus capacitor by semiconductor devices. To avoid any possibility of electric shock from the pins, if they are accessible, a means must be provided for automatically disconnecting the plug from the drive (e.g., a latching contactor).
Grounding (Earthing, equipotential bonding)
The drive must be grounded by a conductor sufficient to carry all possible fault current in the event of a fault. The ground connections shown in the manual must be followed.
Fuses
Fuses or over-current protection must be provided at the input in accordance with the instructions in the manual.
Isolation of control circuits
The installer must ensure that the external control circuits are isolated from human contact by at least one layer of insulation rated for use at the applied AC supply voltage.

Introduction
Epsilon Eb Digital Servo Drive
The Epsilon drives are standalone, fully digital brushless servo drives designed and built to reliably provide high performance and flexibility without sacrificing ease of use.
The use of State-Space algorithms make tuning very simple and forgiving. The drives are designed to operate with up to a 10:1 inertia mismatch right out of the box. Higher (50:1 and more) inertial mismatches are possible with two simple parameter settings.
The drives can be quickly configured to many applications in less than 5 minutes with PowerTools software on a PC running Windows 95, 98, or NT 4.0.
Complete diagnostics are provided for quick troubleshooting. A diagnostic display on the front of the drive informs the user of the operational or fault status. The last 10 faults are stored in non-volatile memory along with a time stamp for easy recall.
Epsilon drives operate at 42 to 264 VAC standalone or at 24 to 375 VDC with an A.P.S. (Alternate Power Supply) and are available in two power ratings. The drive will fit in a 6 inch deep enclosure with cables connected.

Installation
Basic Installation Notes
You are required to follow all safety precautions during startup such as providing proper equipment grounding, correctly fused power, and an effective Emergency Stop circuit which can immediately remove power in the case of a malfunction. See the “Safety Considerations” section for more information.
Electromagnetic Compatibility (EMC)
Drives are designed to meet the requirements of EMC. Under extreme conditions a drive might cause or suffer from disturbances due to electromagnetic interaction with other equipment. It is the responsibility of the installer to ensure that the equipment or system into which the drive is incorporated complies with the relevant EMC legislation in the country of use.
The following instructions provide you with installation guidance designed to help you meet the requirements of the EMC Directive 89/336/EEC.
Adhering to the following guidelines will greatly improve the electromagnetic compatibility of your system; however, final responsibility for EMC compliance rests with the machine builder, and Control Techniques cannot guarantee your system will meet tested emission or immunity requirements.
If you need to meet EMC compliance requirements, EMI/RFI line filters must be used to control conducted and radiated emissions as well as improve conducted immunity.
Physical location of these filters is very important in achieving these benefits. The filter output wires should be kept as short as possible (12 inches is suggested) and routed away from the filter input wires. In addition:
•Choose an enclosure made of a conductive material such as steel, aluminum, or stainless steel.
•Devices mounted to the enclosure mounting plate, which depend on their mounting surfaces for grounding, must have the paint removed from their mounting surfaces and the mating area on the mounting plate to ensure a good ground. See “Achieving Low Impedance Connections” on page 4 for more information.
•If grounding is required for cable grommets, connectors, and/or conduit fittings at locations where cables are mounted through the enclosure wall, paint must be removed from the enclosure surface at the contact points.
•AC line filter input and output wires and cables should be shielded, and all shields must be grounded to the enclosure.

Achieving Low Impedance Connections
Noise immunity can be improved and emissions reduced by making sure that all the components have a low impedance connection to the same ground point. A low impedance connection is one that conducts high frequency current with very little resistance. Impedance cannot be accurately measured with a standard ohmmeter, because an ohmmeter measures DC resistance. For example, a 12-inch-long, 8-gauge,round wire has a significatly higher impedance than a 12-inch-long, 12-gauge, flat braided conductor. A short wire has less impedance than a larger one.
Low impedance connections can be achieved by bringing large areas of conductive surfaces into direct contact with each other. In most cases this requires paint removal because a ground connection through bolt threads is not sufficient. However, component materials should be conductive, compatible, and exhibit good atmospheric corrosion resistance to prevent loss through corrosion, which will hinder the low impedance connection. Enclosure manufacturers offer corrosion resistant, unpainted mounting plates to help.
Bringing components into direct contact cannot always be achieved. In these situations a conductor must be relied upon to provide a low impedance path between components. Remember a flat braided wire has lower impedance than a round wire of a large guage rating.
A low impedance connection should exist among the following components:
•Enclosure and mounting plate
•Servo amplifier chassis and mounting plate
•EMI/RFI AC line filter chassis and mounting plate
•Other interface equipment chassis and mounting plate
•Other interface equipment chassis and electrical connectors
•Enclosure and conduit fittings or electrical connectors
•Enclosure mounting plate and earth ground
•Motor frame and conduit fittings or electrical connectors
•Encoder chassis and electrical connector
A good rule to follow when specifying conductors for high frequency applications is to use a metal strap with a length to width ratio that is less than 3:1.

AC Line Filter Installation Notes
•EMC criteria can be met in installations where multiple drives are supplied through a single filter, however, it is the installers responsibility to verify EMC compliance. Questions on this subject should be directed to the filter manufacturer.
•It is critical that you keep the filter inputs routed away from any electrical noise sources to prevent noise from being induced into them and carried out of the enclosure.

Cable to Enclosure Shielding
Shielded motor, feedback, serial communications, and external encoder cables were used for Control Technicques’ compliance testing and are necessary to meet the EMC requirements. Each cable shield was grounded at the enclosure wall by the type of grommet described earlier and shown in the figure below.

Installation
Figure 3: AC Filter and Cable Connections for Epsilon Drives
Environmental Considerations
If the product will be subjected to atmospheric contaminants such as moisture, oils, conductive dust, chemical contaminants, and metallic particles, you must mount it vertically in a metal NEMA type 12 enclosure.
If the ambient temperature inside the enclosure will exceed 40° C (104° F), you must consider forced air cooling.
Note
For Epsilon drives, surrounding air ambient temperature can be up to 50°C (122° F) with 3% linear derating for every degree above 40° C (104° F)
The amount of cooling depends on the size of the enclosure, the thermal transfer of the enclosure to the ambient air, and the amount of power being dissipated inside the enclosure. Consult your enclosure manufacturer for assistance with determining cooling requirements.

Wiring Notes
•To avoid problems associated with EMI (electromagnetic interference), you should route high power lines (AC input power and motor power) away from low power lines (encoder feedback, serial communications, etc.).
•If a neutral wire (not the same as Earth Ground), is supplied from the building distribution panel it should never be bonded with PE wire in the enclosure.
•You should consider future troubleshooting and repair when installing all wiring. All wiring should be either color coded and/or tagged with industrial wire tabs.
•As a general rule, the minimum cable bend radius is ten times the cable outer diameter.
•All wiring and cables, stationary and moving, must be protected from abrasion.
•Ground wires should not be shared with other equipment.
•Ensure that metal to metal contact is made between the enclosure ground lug and the metal enclosure, not simply through the mounting bolt and threads.
•All inductive coils must be suppressed with appropriate devices, such as diodes or resistor/capacitor (RC) networks.
Mechanical Installation
Drive Mounting
Drives must be back mounted vertically on a metal surface such as a NEMA enclosure. A minimum spacing of two inches must be maintained above and below the drive for ventilation. Side by side drive spacing requirements vary by drive size and RMS loading. Additional space may be necessary for wiring and cable connections.
For drive dimensions, weights and mounting specifications, see the "Specifications" section.
Motor Mounting
Motors should be mounted firmly to a metal mounting surface to ensure maximum heat transfer for maximum power output and to provide a good ground.
For motor dimensions, weights and mounting specifications, see the “Specifications” chapter.

Power Supply Requirements
The examples below show AC power connections for single phase and three phase drives. These examples are shown for reference only. Local electrical codes should be consulted before installation.
The Protective Earth (PE) wire connection is mandatory for human safety and proper operation. This connection must not be fused or interrupted by any means. Failure to follow proper PE wiring can cause death or serious injury.
Epsilon Only
The Eb-202, Eb-203 and Eb-205 drives require 42 to 264 VAC single-phase power. An Epsilon drive can be connected to any pair of power phases on a 1 Ø or 3 Ø power source that is grounded as shown in the following diagrams.
Epsilon Only
If using an APS Logic Power input and the Low DC Bus fault is disabled, minimum supply voltage to an Epsilon can be reduced to 15 VAC on the AC inputs or 24 VDC on the Bus +/- connections.
Note
The maximum voltage applied to the drive terminals must not exceed 264 VAC phase to phase and phase to PE ground. This can be accomplished by referencing the AC supply to earth ground.
Do not connect or disconnect the AC power by inserting or removing the AC power connector. Using the connector in this manner, even once, will damage the connector, making it unusable.
AC Supplies NOT Requiring Transformers
If the distribution transformer is configured as shown in the figures below, the AC power supply can be connected directly to the amplifier terminals.

AC Supplies Requiring Transformers
If the distribution transformer is configured as shown in the figures below, an isolation transformer is required.
If an isolation transformer is used between the power distribution point and the drives, the transformer secondary must be grounded for safety reasons as shown in the figures below.
