Specification
“Caution” used without the safety alert symbol indicates a potentially hazardous situation that, if not avoided,
may result in property damage.
For the purpose of this manual and product, “Note” indicates essential information about the product or the
respective part of the manual.
Throughout this manual, the word “drive” refers to an Epsilon EP drive.
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 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 bonding) - 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.
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.

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 3: High Power Connections, page 10
Step 4: Low Power Connections, page 22
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.
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 that will hinder the low impedance connection. Enclosure manufacturers
offer corrosion resistant, unpainted mounting plates to help.

Specification
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:
•
•
•
•
•
•
•
•

Other interface equipment chassis and mounting plate

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.
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 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.
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 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,

Cable to Enclosure Shielding
Shielded motor, feedback, serial communications and external encoder cables were used for 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 following figure.
Inside Enclosure
Outside Enclosure
O-Ring seals against outside of enclosure
to meet IP68 (comparable to NEMA 6)
Spring Contacts
When Lock Nut is tightened to inside of
enclosure, lock nut will cut through varnished,
anodized, and powder coated finishes.
Tighten lock nut so it cuts through the
finish and into housing.
Cable Shielding
Cable Jacket
Remove 1/2 to 1 inch of cable jacket.
The Spring Contacts will make a continuous
electrical path from the shield of the cable to
equipment ground.
After tightening lock nut and positioning cable
so that Spring Contacts are contacting the
cable shield, tighten Cable Seal Housing.

AC Line Filter Installation Notes
•
•
It is important to keep the filter inputs routed away from any electrical noise sources.
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.
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.
