Safety Information

Safety Precautions

This product is intended for professional incorporation into a complete system by qualified persons. 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 must 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 this instruction manual carefully.

Qualified Person

For the purpose of this manual and product, a “qualified person” is one who is familiar with the installation,
construction and operation of the equipment and the hazards involved. In addition, this individual has the following
qualifications:

Is trained and authorized to energize, de-energize, clear and ground and tag circuits and equipment in accordance
with established safety practices.

Is trained in the proper care and use of protective equipment in accordance with established safety practices.
Is trained in rendering first aid.

Enclosure

This product is intended to be mounted in an enclosure that prevents access except by qualified persons and that
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 provided where needed.

Identification of Safety Information

Safety related information through out this manual is identified with the following markings.

“Warning” indicates a potentially hazardous situation that, if not avoided, could result in death or serious injury.

“Caution” indicates a potentially hazardous situation that, if not avoided, may result in minor or moderate
injury.

Safety Information v

Safety Information Product Overview Installation Diagnostics

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.

Supply isolation device

The AC supply or high voltage DC 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 Epsilon EP206/209/216 and 3 minutes for Epsilon EP202/204 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 bo nding) - High Leakage Current

The drive must be grounded by a conductor sufficient to carry all possible fault current in the event of a fault. This
equipment has high earth leakage current. You must comply with local safety regulations with respect to minimum
size and special installation requirements on the protective earth conductor for high leakage current equipment.
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.
The drive alone does not provide branch circuit protection. Branch circuit protection must be provided in
accordance with the National Electrical Code and any additional local codes.

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. External control circuits identified as PELV circuits do
not need this isolation when they are completely within a zone of equipotential bonding, generally within a single
enclosure or group of enclosures bonded together.

Product Overview

Epsilon EP Drive

The Epsilon EP drive is a stand-alone, fully digital brushless servo drive 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) inertia mismatches are possible with two
simple parameter settings.

The Epsilon EP drive can be quickly configured to many applications in less than 5 minutes with PowerTools Pro
software on a PC running Windows® 98, NT 4.0, 2000, ME and XP.

Complete diagnostics are provided for quick troubleshooting. A status/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.

Installation

Installation of the Epsilon EP drive is completed by following a simple step-by-step process. The Epsilon EP
installation begins by mounting the drive to a metal mounting panel. Next, the high power connections are made to
the drive, then the low power connections are made.

Step 1: Basic Installation and Panel Layout, page 3
Step 2: Mechanical Installation, page 8
Step 3: High Power Connections, page 13
Step 4: Low Power Connections, page 31

Step 1: Basic Installation Guidelines

You are required to follow all safety precautions during start-up 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 Americas LLC 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 practical 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 3 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.

• Cables should be shielded, and all shields must be grounded to the enclosure.

To meet radiated emissions requirements, the enclosure door must be closed and have electrical conduction at
hinges and closure hardware or be fitted with a conductive gasket. Route cables away from the door where possible
to minimize coupling emissions to door where they can re-radiate. The door generally must be bonded to the
enclosure for electrical safety, but this is not sufficient to meet EMC.

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 significantly higher
impedance than a 12 inch long 12 gauge flat braided conductor. A short wire has less impedance than a long one.

Multiple connections such as at the four corners of a plate provide much lower impedance than a single connection.
Straight line connections provide much lower impedance than ones with bends or corners.

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

Installation 3

Safety Information Product Overview Installation Diagnostics

resistance to prevent loss through corrosion that 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 gauge rating.

A low impedance connection should exist between the following components, but not limited to:

• Enclosure and mounting plate

• Enclosure and door, if door does not have RF gaskets

• Servo drive chassis and mounting plate

• EMI/RFI AC line filter chassis and mounting plate

• Other interface equipment chassis and mounting plate

• Cable shields and enclosure, or terminal block, or connector

• 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

Electrostatic Discharge (ESD) Protection

Do not allow ESD to the drive while operating.

Though no damage occurs with electrostatic discharge at levels tested for EMC compliance, ESD directly to the drive
cover can interrupt proper drive operation. ESD to terminals on the breakout boards has not been evaluated because
wiring to these terminals is a maintenance activity. When doing any maintenance activity, make sure static electric
charge is drained off by touching the enclosure away from the drive before contacting the drive or its wiring terminals.
Use of ground straps or other techniques to prevent static buildup is a necessary part of any maintenance activity.

Environmental Considerations

The drive is rated to operate only in a pollution degree 2 environment, meaning that normally only non-conductive
pollution occurs and there is no condensation, but occasional condensation may occur when not operating.

If the installation environment contains 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.

To prevent operation with condensation present, it is best to energize the logic power several minutes before
applying main power or keep logic power applied continuously.

If the ambient temperature inside the enclosure will exceed 40°C (104°F), you must consider forced air cooling.

It is necessary to maintain the drive surrounding air temperature at 40°C (104°F) or 50°C (122ºF) with
appropriate derating or below to maintain the drive UL ratings. See “Specifications” on page 65.for derating
by model.

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.

The power dissipated by a EP202-P is 35 W, a EP204-P is 55 W, a EP-206-P is 85 W, a EP209-P is 115 W and a
EP216 is 200 W. The power dissipation values includes up to 12 W of power from the logic power supply.

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.).

Safety Information Product Overview Installation Diagnostics

• 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.

Options and
Accessories

Specification

• 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 or "daisy-chained" with other equipment.

• Ensure that full metal to metal surface 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, except as described in this manual.

• If using a non-shielded Ethernet cable, install a clamp on ferrite, Control Techniques part number 157016-07,

Step 2: Mechanical Installation

The drive must be back mounted vertically on a metal mounting panel such as a NEMA enclosure, Additional space
is necessary above and below the drive for wiring and cable connections.

To allow sufficient air flow for cooling, leave at least 0.25" [6.3 mm] clear space on vented cover (left) side plus 0.50"
[12.7 mm] on heatsink (right) side. Leave additional space if cables are routed through this space.

When drilling holes in mounting plate or trimming wires during installation of this or other equipment, do not
allow drill shavings or wire trimmings to enter the EP drive. Such foreign objects can compromise electrical
isolation creating a hazard or result in equipment failure.

Specification

Fixed Protective Earth (PE) connections are mandatory for human safety and proper operation. These
connections must not be fused or interrupted by any means. Failure to follow proper PE wiring can cause
death or serious injury. This equipment has high earth leakage current and requires a redundant PE
connection from either terminal marked PE at J8 to PE connection point.

AC Power Requirements

The Epsilon EP drives require 20 Vac to 264 Vac single phase power but, may operate on DC supplies, (See
Operation on DC Supply). An Epsilon EP 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. Local electrical codes should be consulted before
installation.

When operating the drive at 90 V or less disable the Low DC Bus fault so the drive does not fault.

Where regeneration occurs, bus voltage will rise to 400 Vdc before shunt operation or a High DC Bus fault
limit voltage, whether shunt resistor is installed or not. Motors must have insulation rated for inverter duty at
240 Vac no matter what the operating voltage is, or bus voltage must be limited by other means.

The maximum voltage applied to the drive terminals must not exceed 264 Vac phase to phase and phase to
PE ground. The AC supply must be earthed (type TN) with PE connected to the earthed point at the source,
which is usually a distribution transformer but could be a service entrance.

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 drive terminals.

Transformer Sizing

If your application requires a transformer, choose a transformer with a continuous power rating greater then the
maximum power usage of the drive/motor combination. Other factors that may influence the required KVA rating are
high transformer ambient temperatures (>40° C or >104° F) and drive operation near the maximum speeds.

Transformer output voltage drop may become a limiting factor at motor speeds and loads near maximum ratings.
Typically, higher KVA transformers have lower voltage drop due to lower impedance.

When multiple drives are connected to a single isolation transformer, add the suggested KVA ratings of the drives
that would be operating simultaneously together for transformer sizing.
