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.
iv
Safety Information Product Overview Installation Diagnostics Options and
Accessories Specification
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.
“Caution” used without the safety alert symbol indicates a potentially hazardous situation that, if not avoided,
may result in property damage.
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.

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 7
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.

Safety Information Product Overview Installation Diagnostics Options and
Accessories 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:
• 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
• 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.
Electrostatic Discharge (ESD) Protection
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.
Do not allow ESD to the drive while operating.

• 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,

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.

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.
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.
Figure 7: Earth Grounded WYE Distribution Transformer, 120/208Y 3Ø
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.
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.

Transformer Sizing
If your application requires a transformer, use the following table for sizing the KVA rating. The values in the table
are based on “worst case” power usage and can be considered a conservative recommendation. You can down-size
the values only if the maximum power usage is less than the transformer continuous power rating. 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.

AC Input Power Connections
Figure 14: Epsilon EP AC Power Wiring Diagram
Operation on DC Input Supply
At this time, the EP drive is not UL listed for operation on a DC input supply.
The EP drive can operate on DC input as low as 10 Vdc, though recommended minimum is 24 Vdc. It can also
operate from a common DC link with voltage to 373 Vdc, the voltage resulting from 264 Vac applied to a rectifier,
with regen to 400 Vdc intermittently.
For DC input supply less than 24 Vdc, the DC input should be connected to the B+ and B- terminals at J8 to avoid
losses in the rectifier and inrush limiter. At such low voltages the bus caps do not need inrush protection. For DC
supply greater than 24 Vdc, the supply should be connected to L1 and L2 terminals on J1. Polarity does not matter.
The rectifier blocks reverse current so regen energy will not come back to the supply. DC supply greater than 24 Vdc
may be applied to the B+ and B- terminals of J8, but the supply must provide soft-start or inrush current limiting and
must be able to handle any anticipated regen energy.
Power must be "Off" for a minimum of 6 minutes for the Epsilon EP206 drive and 3 minutes for the Epsilon
EP202/204 drives before unplugging the power connection. This will ensure the bus voltage has bled down to a
safe level (below 50 Vdc).
Do not connect or disconnect 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.

Both supply conductors must be fused except one that is grounded. The fuse must be rated for at least the voltage
applied. The current rating of the fuse should match the rated output current of the drive. A slow-blow fuse should
be used if high peak loads are expected.
External Shunt Electrical Installation
The EP204 and EP206 drives provide an internal shunt transistor to direct regen energy to an external shunt or
braking resistor. The resistor is connected to the B+ and SH terminals at J8 on the top of the drive.
Shunt Control
The shunt transistor turns on when the bus voltage reaches 405 Vdc and shuts off when the bus voltage falls below
390 Vdc. An internal shunt control algorithm is used to prevent the external shunt resistor from overloading. It is
necessary to enter shunt energy rating, power rating and resistance for the attached shunt resistor in PowerTools
Pro software. Energy rating is the amount of energy that the resistor can absorb in a single shunt event assumed to
be so short that power dissipation is negligible. Power rating is the long term average power that can be dissipated.
PowerTools Pro default values are for the Control Techniques "SM-Heatsink DBR-1" resistor kit, marked P/N 1220-
2756-01 on the resistor.
External Shunt Resistor
Control Techniques offers an external shunt resistor kit, SM-Heatsink DBR-1, that attaches directly to the EP drive
heatsink. The resistance is 75 Ohms and has 1500 Joule energy rating and 50 W continuous power rating. It is
adequate for most infrequent machine stop sequences due to relatively high energy rating for its power rating. It
should be suitable for any EP204 application unless average power exceeds 50 W for repetitive cycles. For an
EP206, some applications may require lower resistance to prevent a high bus fault or higher energy rating for a single
event, as well as higher average power rating. The resistor in the kit is designed to eventually open in the event of
a shorted control transistor when operating with an AC input greater than 200 Vac. At this time the kit should be used
only when the drive is operating at 200 Vac to 240 Vac.
A different external shunt resistor should be used if average power is above 50 W, or other limits are exceeded as
described above. Higher power resistors should be mounted away from the drive to prevent overheating. If thermal
loading inside a cabinet is an issue, a resistor with suitable enclosure may be installed external to the drive enclosure.
The minimum resistance for an external shunt resistor is 33 Ohms. The resistor must have thermal overload
protection to remove power in the event of a shorted control transistor. The protection can simply open the circuit, in
which case a high bus fault will occur, or be wired to a contactor that isolates input power from the drive on overtemp.
Shunt Resistor Kit Installation
The SM-Heatsink DBR-1 attaches to the side of an EP204 or EP206 drive by lining up the two captive screws to the
special width slots in the heat sink. The exact position along the slot does not matter as long as the body of the
resistor does not extend beyond the top or bottom of the drive. Use a T-20 Torx driver to thread the screws into
position. After both are well started but not tight, carefully turn each screw until it is seated against the resistor and
the resistor back is seated against the heat sink. Then turn the screw 1/8 turn more. Do not overtighten.
Strip 0.12 inch [3.0 mm] insulation from the ends of the resistor wires. Install the wires in the SH and B+ terminals of
J8 and tighten to 5 in-lb. Make sure the locking screws are installed on J8 to prevent the connector from pulling out.
Shunt connections at J8 remain at dangerous Voltages after disconnecting AC Power. Power must be "Off"
for a minimum of 6 minutes for an EP206 and 3 minutes for an EP202/204 before touching these terminals.

Motor Power Wiring
The following paragraphs provide details of motor connections. When motor power cables are long, 100ft. [30 m], a
ferrite (Control Techniques p/n 157016-13, Steward p/n 28A3851-0A2 or equivalent) installed on the three phase
conductors but not the shield, near J1 can significantly reduce high frequency switching harmonics that in some
cases can cause communications errors. Maximum cable length is 200 ft [60 m]. J1 terminals are suitable for one
18 AWG to 14 AWG or ISO 0,75 to ISO 2,5 stranded conductors. The ground/shield terminal may contain the shield
and ground conductors together if each is 16 AWG or ISO 0,75 or ISO 1,5. Otherwise a ferrule must be used to crimp
both connectors together.

Step 4: Low Power Connections
DC Logic Power Supply Wiring
The Epsilon drive requires a user supplied logic power supply, 24 Vdc ±10%, to power the internal logic of the drive.
Use the table below to determine the current requirements of the application. Users should consider keeping logic
power energized at all times because it helps prevent condensation and maintains position information in the drive.
Logic Power Supply Specification
Figure 19: Logic Power Supply Wiring Diagram
For UL applications, the logic power supply must be a UL recognized or UL listed limited voltage/limited energy or
limited voltage/limited current supply, or a limited voltage supply with overcurrent protection appropriate for the wiring
and not to exceed 12 A. Isolate line connected circuits from low voltage circuits.
For applications to meet the EU Low Voltage Directive, an approved 24V supply must be used and the negative side
must be grounded to PE. PELV circuits must have protective separation for 300 V system voltage from mains
connected circuits, including separation between encoder circuits and motor power wiring. If all circuits connected

to the logic supply are PELV, the wiring need not be isolated from direct contact within a zone of equipotential
bonding, normally an enclosure or set of enclosures bonded together. Otherwise, logic wiring and circuits must be
isolated from direct contact by basic insulation for 300 V system voltage.
In all applications, do not interconnect extra low voltage power supplies so that voltages add.
Motor Feedback Wiring (J6)
Encoder feedback connections are made with the 15-pin high density “D” connector (J6) on the drive. Maximum
feedback cable length is 200 ft [60 m].
Connection of Encoder Quadrature and Marker Signals
For A, A/, B, B/ and Z, Z/ pairs, Control Techniques cables use low capacitance (~10 pf/ft) wire to get a high
characteristic impedance and low loss. The differential input circuit accepts RS-485 level signals, but if the differential
voltage is less than ±400 mV, an encoder fault is generated.
Connection of Encoder Commutation Signals to the Drive
The drive is capable of receiving U, V, and W commutation signals from either a differential or single ended source.
Figures 20 through 22 show a simplified circuit for the U, U/, V, V/, W, and W/ inputs on the drive. For single-ended
encoder outputs, leave U/, V/, and W/ unconnected at the drive. No PowerTools configuration is required. U, V, and
W have a 1K pull-up to 5V. Logic threshold is about 2.5 V with 0.1 V hysteresis.
Motor Overtemp Wiring
The motor overtemp circuit is compatible with PTC thermistor sensor with 1K resistance at the over temperature trip
point. The circuit provides 5V open circuit and 0.5 mA closed contacts to an overload switch. For motors without over
temperature protection sensors, pins 14 and 15 of J6 must be shorted together to prevent an overtemp fault in the
drive.

Motor Brake Wiring
The NT and MG motors equipped with brakes have a three-pin MS style connector. The brake power cable (model
CBMS-XXX) has an MS style connector on the motor end and three wire leads on the drive end (see the following
wiring diagrams). The XV 40-80 mm motors with brakes have a two-position connector. The brake power cable
(model XTBMS-XXX) has a two position connector on the motor end and three wire leads on the drive end. The XV
130 mm motors equipped with brakes have two MS style connectors; one is the encoder feedback and the other has
the motor power and brake connections. The motor power/brake cable (model XCMDBS-XXX) has an MS style
connector on the motor end and six wire leads on the drive end.
You must provide a DC power supply rated at +24 Vdc with a 2 A minimum current capacity for the brake. If you use
this voltage source to power other accessories such as I/O or more than one brake, size the power supply for total
load.

Inputs are ON with +10 Vdc to +30 Vdc applied and OFF when less than +1.5 Vdc or 0.2 mA is applied. Input current
at 24 Vdc is 4.8 mA and input resistance is about 4.8k ohms.
Maximum load on each output channel is 150 mA with 3.5 Vdc max voltage drop from I/O supply + to output. Outputs
are rugged and require no freewheeling diode on inductive loads. Outputs are short-circuit proof to ground (0 V) or
any voltage from 0V to the I/O power supply voltage.
Optical isolation for I/O is functional only and does not provide safety rated isolation. I/O circuits must be PELV for
any extra low voltage circuits to be PELV. For UL installations, I/O wiring must be from a limited voltage/limited
energy or limited voltage.limited current supply.
Figure 26: Epsilon EP-B Input/Output Wiring Diagram
As part of PELV wiring, I/O circuits are intended to be used within a zone of equipotential bonding where cables or
wiring would typically be no more than 10 ft [3 m] long. These circuits have not been evaluated for EMC immunity
which would be required for longer cables.
I/O Connector (J3) Functions
The I/O connector is a 26-pin male high-density dsub connector on the front of the drive. A low profile standard
terminal interface board (STI-24IO) and cable assembly (EIO26-xxx) are available for making connections
convenient. Figure 26 shows pin-outs for I/O channels supported in the EP-B drive and for external wiring typical of
all I/O channels. Figure 27 shows pin-outs for EP-I and EP-P models. Input channels 1-8 have high speed capture
capability in the EP-P models. Figure 28 shows the STI-24IO interface board for discrete wiring to I/O.

Communications
Communications with the drive is provided through the RJ45 connectors located on the front of the drive. The two
RJ45 connectors are identical and are used to provide a way to daisy chain two or more drives together using the
DDC-RJ45 cable, see Figure 44. The Epsilon EP serial communication connector (serial port) as standard, supports
2 wire EIA485 communications. The RS-485 communications port is not isolated from drive electronics and the "0
V" pins are internally connected through a 10 Ohm resistor to PE. Interconnected drives should be within a zone of
equipotential bonding. Connection to a master device on the network, such as a MMI, SCADA, PLC, or PR can be
remote, but care should be taken to make sure the entire network operates within the +/-7 V common mode voltage
range of RS-485. Though the comm port is part of PELV circuits when properly installed, if the master device is
outside the zone of equipotential bonding the circuit needs to be isolated against direct contact. The minimal RS-485
network cable contains a shielded twisted pair for RX TX (pin 2) and /RX /TX (pin 7) with shield to the shell, though
a 0 V reference signal (pin 3) can improve immunity to ground differentials. See the following table for the connection
details for the RJ45 serial communication connector.
The provision for connection of the internal 120 ohm terminating resistor at pin 1 and pin 8 would rarely, if ever, be
needed unless data rates much higher than 19.2K are supported. Since a terminator connection is only made at the
end of a trunk, it is most conveniently accomplished by crimping a short link from pin 1 to pin 8 in a new RJ45
connector and plugging it into the second RJ45 port on the "last" drive. Cable conductors should not be connected
to these pins.
Communication Cables
The CT-Comms cable is an isolated RS-232 to RS-485 convertor that may be used to connect one or more EP drives
to a master device using a standard 9 pin D-sub RS-232 serial comms port. The +15 V supply at pin 4 and the 0 V
connection at pin 5 are intended only to provide power to the isolators in the CT-Comms cable and are not to be used
for any other purpose.
The TX Enable signal at pin 6 and 0 V at pin 3 provide a transmit enable signal from each interconnected drive to a
CT-Comms cable and are not to be used for any other purpose. They may be wired from drive to drive in a zone of
equipotential bonding to allow the CT-Comms cable to communicate with all drives in the group.
The DDC-RJ45 provides drive to drive (daisy chain) connections between EP drives, including support for the CT-
Comms cable in a group of drives.

Fault Descriptions
Flash Invalid
This fault indicates that the firmware checksum has failed. From the Tools>Program Flash menu in PowerTools Pro
the firmware stored in flash memory can be reprogram or upgrade. If this problem persists, call Control Techniques.
A common cause would be an interrupted F/W Flash upgrade (cable disconnected during an upgrade process).

Diagnostics and Troubleshooting 45
Safety Information Product Overview Installation Diagnostics Options and
Accessories Specification
NVM Invalid
At power-up the drive tests the integrity of the non-volatile memory. This fault is generated if the contents of the non-
volatile memory are invalid.
Invalid Configuration
This fault will occur if the digital board in the drive does not match the power board settings. It is only useful during
manufacturing. A drive with this fault should be returned for service.
Drive Overtemp
Indicates the drive IGBT temperature has reached an over temperature condition. This fault is not currently
implemented in the EP drive.
Power Module
This fault is generated when a power stage over-temperature, over-current or loss of power stage logic supply
occurs. This can be the result of a motor short to ground, a short in the motor windings, a motor cable short or the
failure of a switching transistor.
High DC Bus
This fault will occur whenever the voltage on the DC bus exceeds the High DC Bus threshold. The most likely cause
of this fault would be an open external shunt, a high AC line condition, or an application that requires an external
shunt (e.g., a large load with rapid deceleration) but none is installed.
Low DC Bus
This fault will occur whenever the voltage on the DC bus drops below the Low DC Bus threshold. The most likely
cause of this fault is a reduction (or loss) of AC power. A 50 ms debounce time is used with this fault to avoid faults
caused by intermittent power disruption. With an Epsilon EP drive, the low DC bus monitoring can be disabled. In an
EP-B and EP-I this fault is disabled by clearing the check box on the Faults view, and for an EP-P the check box is
located on the Advanced view
Encoder State
Certain encoder state transitions are invalid and will cause the drive to report an encoder state fault. This is usually
the result of noisy encoder feedback caused by poor shielding. For some types of custom motors it may be necessary
to disable this fault. With an Epsilon EP drive, the Encoder State monitoring can be disabled. In an EP-B and EP-I
this fault is disabled by clearing the check box on the Faults view, and for an EP-P the check box is located on the
Advanced view.
High DC Bus Threshold
Epsilon EP 415 Vdc
Low DC Bus Threshold
Epsilon EP 60 Vdc

Safety Information Product Overview Installation Diagnostics Options and
Accessories Specification
Encoder Hardware
If any pair of complementary encoder lines (A, B, Z) are in the same state, an encoder line fault is generated. Also,
can be generated if all three commutation channels (U, V, W) are 0 or 1, an illegal state. The most likely cause is a
missing or bad encoder connection.
Motor Overtemp
This fault is generated when the motor thermal switch is open due to motor over-temperature or incorrect wiring.
Overspeed
This fault occurs in one of two circumstances:
1. When the actual motor speed exceeds the Overspeed Velocity Limit parameter or 150% of motor maximum
operating speed. This parameter can be accessed with PowerTools Pro software.
2. If the combination of command pulse frequency and Pulse Ratio can generate a motor command speed in
excess of the fixed limit of 13000 RPM, an Overspeed Fault will be activated. In Pulse mode operation and any
Summation mode which uses Pulse mode, the input pulse command frequency is monitored and this
calculation is made. For example, with a Pulse Ratio of 10 pulses per motor revolution, the first pulse received
will cause an Overspeed fault even before there is any motor motion.
RMS Shunt
This fault is generated when filtered average shunt power dissipation is greater than the design rating of the shunt
resistor.
Following Error
This fault is generated when the following error exceeds the following error limit (default following error limit for an
EP-I and EP-B is 0.2 revs). With PowerTools Pro you can change the Following Error Limit value or disable it in the
Position view. In an EP-B and EP-I the Following Error Limit is functional in Pulse mode only.
Travel Limit +/-
This fault is caused when either the + or - Travel Limit input function is active.
Sync Fault
This fault occurs when the user selected trajectory update rate is set too shortbased on the processor requirements.
The three possible trajectory update rates are 800µs, 1200 µs, or 1600 µs. Try changing the trajectory update rate
to the largest value (1600 µs) and run the application again. If the problem persists after setting to 1600 µs, contact
Control Techniques technical support. For more information on the trajectory update rate see the Epsilon EP-P
Drive and FM-3/4 Modules Reference Manual (P/N 400518-04).
Run Time Faults (EP-P only)
The "4" fault is caused by any of the following internal routine faults:
Trajectory Fault #1
This fault occurs when the drive commands motion that cannot be achieved due to excessive following error, accel,
decel, velocity settings, or unuseable user units. Check the user units, velocities, accels and decels for correct
values.
Diagnostics and Troubleshooting 47
Safety Information Product Overview Installation Diagnostics Options and
Accessories Specification
Trajectory Fault #2
This fault occurs when using the "Using Capture.#" option in a user program. If the capture has never been triggered,
or the capture data has gone "stale", the drive will not be able to process motion properly.
Program Fault
This fault indicates a problem was encountered in a user program. For example: an illegal math operation resulting
in a divide by zero or overflow of 32-bit data. This error can also occur if trying to access a drive parameter that is
non-existent or not available to the user.
Invalid Configuration Fault #2
The user program in flash memory will not run. Download the user program again using PowerTools Pro. A common
cause of this fault could be an interrupted configuration download, such as a cable being disconnected during the
download.
No Program
This fault will be displayed on initial power-up indicating that no configuration has been downloaded to the drive. To
clear the fault, download a valid configuration to the drive.
All "On"
This is a normal condition during power up of the drive. It will last for less than 1 second. If this display persists, call
Control Techniques Americas LLC for service advice.
Normally, "All On" for less than one second during power-up. All segments dimly lit when power is "Off" may occur
when an external signal is applied to the encoder inputs (motor or master) or serial port from an externally powered
device.
Diagnostic Analog Output Test Points
The drive has two 10-bit real-time Analog Outputs which may be used for diagnostics, monitoring or control
purposes. These outputs are referred to as Channel 1 and Channel 2. They can be accessed from the Analog/Sync
Output Connector (J5) on the drive.
Each Channel provides a programmable Analog Output Source.
Analog Output Source options are:
• Velocity Command
• Velocity Feedback
• Torque Command (equates to Torque Command Actual parameter)
• Torque Feedback
• Following Error
• Position Feedback (EP-B, EP-I, and EP-IDN)
• Custom Variable (EP-P only)
• Analog In (EP-P only)
Drive Faults
The Active Drive Faults dialog box is automatically displayed whenever a fault occurs. There are two options in this
dialog box: Reset Faults and Ignore Faults.

Resetting Faults
Some drive faults are automatically reset when the fault condition is cleared. Other faults require drive logic power
to be cycled or the drive to be “rebooted”. If you wish to continue working in the PowerTools Pro software without
resetting the fault, click the Ignore Fault button.
To reset faults that can be reset with the Reset Faults button, simply click the Reset Faults button in the Drive Faults
Detected dialog box or push the Reset button on the front of the drive where the fault occurred.
