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

Manual

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

vii

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.

Epsilon Eb Digital Servo Drive Installation

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.

Epsilon Eb Digital Servo Drive 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.

Manual

Installation

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.

Epsilon Eb Digital Servo Drive Installation Manual

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.

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.

7

Epsilon Eb Digital Servo Drive Installation Manual

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.

10

Figure 5: Earth Grounded WYE Distribution Transformer

Figure 6: Earth Grounded Delta Distribution Transformer

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.

Figure 10: Single Phase Power Supply Connections

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.

Installation

Drive/Motor Combination Suggested KVA Rating

Eb-202/NT-207 1.0

Eb-203/NT-207 1.0

Eb-202/NT-212 1.2

Eb-203/NT-212 1.7

Eb-203/MG-316 2.3

Eb-205 / MG-340 3.0

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.

elapsed since power off, the inrush current will be higher.

14

Input Power Connections

Epsilon Only

Power must be "Off" for a minimum of 6 minutes for the Epsilon drive before unplugging
the power connection, to ensure the bus voltage has bled down to a safe level (below 50
VDC).

Figure 11: Epsilon AC Power Wiring Diagram

Installation

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.

15

Epsilon Eb Digital Servo Drive Installation Manual

Figure 12: Epsilon Auxiliary Power Supply Wiring Diagram

Alternate Power Supply Wiring

An Alternate Power Supply (APS) allows the drive to retain motor position information and
serial communications when the main AC power supply is disconnected. You must reset the
drive, either using the reset button or a reset input, after AC power is re-applied if the backup
supplies have been active.

Enabling APS power is done by sliding open the access panel on the side of the drive. Then
move the jumper into the APS position using needle nose pliers.

16

Use static control procedures when handling the jumper inside the drive case.

The APS input is isolated from all other circuits on the Epsilon drive including the DC bus,
logic and I/O. This permits you to use one common 24 VDC power supply for multiple drives
without concern for ground loops and noise coupling between drives. The APS connection
will generate some high frequency ripple (.25 Amps at 80 khz) on the APS power lines. This
may disturb sensitive equipment that shares the same power supply.

( 0.4 A maximum

0.6 A peak if external

power supply

Using the APS supply input to power the drive logic and motor encoder allows the drive bus
to operate at DC voltages below 42 VAC (60 VDC bus). The drive will operate down to 12
VDC on the bus (10 VAC on L1 and L2). However the low DC bus monitoring must be
disabled to prevent faults at these low DC bus voltage levels. This can be done with
PowerTools software on the Advanced tab in Detailed Setup mode.

Do not wire AC line into the APS input. Doing so will damage the drive.

Do not open the APS jumper access panel until at least six minutes after the main AC
power has been removed from the L1 and L2 terminals.

Note

Connecting 24V common on the APS to chassis ground reduces offset voltage in Analog
Diagnostic Outputs.

17

Epsilon Eb Digital Servo Drive Installation Manual

Figure 13: Multiple APS Wiring Diagram

Motor Power Wiring

Motors are equipped with up to three male MS (Military Style) connectors, one for stator
connections, one for encoder connections and one for the brake (if so equipped).

Stator connections from the drive to the motor are made with the CMDS cable which has a
female MS style connector on the motor end and four individual wires and shield that connect
to the motor power connector on the bottom of the drive.

18

Figure 14: Epsilon Motor Power Wiring Diagram

Note

The motor ground wire and shields must be run all the way back to the amplifier terminal
and must not be connected to any other conductor, shield or ground.

Motor Feedback Wiring

Encoder feedback connections are made with the CFCS cable. This cable has an MS style
connector on the motor end and a 26-pin high density “D” connector on the drive end.

For A, A, B, B and Z, Z pairs, the CFCS cable uses low capacitance (~10 pf/ft) wire to get a
characteristic impedance of 120 ohms. This impedance match is important to minimize signal
loss and ringing.

Installation

Figure 15: Motor Feedback Connector Pinout

Motor Brake Wiring

Motors equipped with brakes have a three-pin MS style connector. The Control Techniques
brake power cable (model CBMS-XXX) has an MS style connector on the motor end and
three wire leads on the amplifier end (see wiring diagram below).

You must provide a DC power supply rated at +24 VDC with a 2 amp 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, you must increase its current capability.

difference is the CMDO cable has a male connector on one end with open wires on the other
while the CMDX cable has male connectors on both ends.

24

For information about CMDO-XXX and CMDX-XXX (18 pair cable) cable wire colors see
the “Specifications” chapter.

Note

Some CMDO and CMDX cables may have White/Yellow and Yellow/White wires in
place of the White/Orange and Orange/White shown in the figure above (pins 6 and 21).

The CDRO cable includes only the most commonly used signals to reduce the cable outer
dimension and has a connector at only one end. The 45 degree connector design used on the
CDRO cable also reduces the enclosure spacing requirement below the drive.

For information about the CDRO-XXX (13 pair) cable wire colors, see the “Specifications”
chapter.

Encoder Output Signal Wiring

The Epsilon drive encoder outputs meet RS-422 line driver specifications and can drive up to
ten RS-422 signal recievers.

The default encoder output resolution is set so it outputs the actual motor encoder resolutions.
The standard MG and NT motors have 2048 lines per revolution. This resolution is adjustable
in one line per revolution increments with PowerTools software. With the range of one line
per revolution to the actual motor encoder density.

Serial Communications

Serial communications with the drive is provided through the female DB-9 connector located
on the front of the drive. The serial interface is either three wire non-isolated RS-232C or two
wire non-isolated RS-485. RS-485 is also available through the 44-pin Command Connector.

30

Figure 30: Epsilon RS-232 and RS-485 Internal Connections between the Command

Connector and the Serial Communication Connector

When connecting the serial port of your PC to the serial port of the drive, verify that your
PC’s ground is the same as the drive PE ground. Failure to do so can result in damage to
your PC and/or your drive.

Note

Communication errors can usually be avoided by powering the computer or host device
off of a convenience outlet that is mounted in the enclosure and whose neutral and ground
are wired to the same single ended point ground that the drives and controllers are using.

This is sometimes benefical even with battery powered computers.

Modbus Communications

The drive’s serial communication protocol is Modbus RTU slave with a 32 bit data extension.
The Modbus protocol is available on most operator interface panels and PLC’s.

Diagnostics and Troubleshooting

Diagnostic Display

The diagnostic display on the front of the drive shows drive status and fault codes. When a
fault condition occurs, the drive will display the fault code, overriding the status code. The
decimal point is “On” when the drive is enabled and the Stop input is not active. This indicates
that the drive is ready to run and will respond to motion commands. Commands will not cause
motion unless the decimal point is “On”.

character will only appear if the Brake output
function is assigned to an output line.

Stall Foldback

Drive output current is limited to 80 percent of
drive stall current.

33

Epsilon Eb Digital Servo Drive Installation Manual

Display Indication Status Description

Ready to Run Drive enabled, no Stop input.

Fault Codes

A number of diagnostic and fault detection circuits are incorporated to protect the drive. Some
faults, like high DC bus and amplifier or motor over temperature, can be reset with the Reset
button on the front of the drive or the Reset input function. Other faults, such as encoder
faults, can only be reset by cycling power “Off” (wait until the status display turns “Off”),
then power “On.”

The drive accurately tracks motor position during fault conditions. For example, if there is a
Low DC Bus fault where the power stage is disabled, the drive will continue to track the
motor’s position provided the logic power is not interrupted.

The +/- Travel Limit faults are automatically cleared when the fault condition is removed.
The table below lists all the fault codes in priority order from highest to lowest. This means
that if two faults are active, only the higher priority fault will be displayed.

Power Up Test

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.

35

Epsilon Eb Digital Servo Drive Installation Manual

Invalid Configuration

Epsilon Only

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 100° C.

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.

It can also occur if the drive enable input is cycled “Off” and “On” rapidly (>10 Hz).

This fault should not be allowed to occur repeatedly. System changes should be made to
eliminate Z fault events. Drive power stage will become degraded if allowed to continue.

Note

If a cause for Z faults cannot be determined, write down all observations prior to and after
the Z faults and contact Control Techniques Technical Support.

36

High DC Bus

This fault will occur whenever the voltage on the DC bus exceeds 415 VDC. The most likely
cause of this fault would be an open external shunt fuse, a high AC line condition or an
application that requires an external shunt (e.g., a large load with rapid deceleration).

High DC Bus Threshold Low DC Bus Treshold

E Series 440 96

Epsilon 415 60

Low DC Bus

This fault will occur whenever the voltage on the DC bus drops below 60 volts. 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 and Epsilon drive,
the low DC bus monitoring can be disabled with PowerTools software in the Advanced tab.

Diagnostics and Troubleshooting

High DC Bus Threshold Low DC Bus Treshold

E Series 440 96

Epsilon 415 60

Encoder State

Certain encoder states and 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.

Encoder Hardware

If any pair of complentary encoder lines are in the same state, an encoder line fault is
generated. 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
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.

Max Following Error

This fault is generated when the following error exceeds the following error limit (default
following error limit is .2 revs). With PowerTools you can change the Following Error Limit
value or disable in the Position tab.

37

Epsilon Eb Digital Servo Drive Installation Manual

Travel Limit +/-

This fault is caused when either the + or - Travel Limit input function is active.

“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 for service advice.

Normally, “All On” appears for less than one second during power-up. All segments are
dimly lit when power is “Off.” This is normal when an external signal is applied to the
encoder inputs (motor or master) or serial port from an externally powered device. The
signals applied to the inputs cannot exceed 5.5V level required to drive logic common or drive
damage will occur.

Diagnostic Analog Output Test Points

The drive has two 8-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 Command Connector on the drive or from the Diagnostics
Analog Output Pins located on the front of the drive.

Each Channel can be programmed to the following sources:

The DGNE cable was designed to be used with either an oscilloscope or a meter. The wires
are different lengths to avoid shorting to each other. However, if signals do get shorted to
GND, the drive will not be damaged because the circuitry is protected.

ECI-44 External Connector Interface

The ECI-44 allows access to all command and input and output signals. The ECI-44 should
be mounted close to the drive and away from any high voltage wiring. The ECI-44 comes
complete with the hardware necessary for mounting to most DIN rail mounting tracks.

44

Figure 39: Dimensions of ECI-44

Note

Shield connection points are connected to the shell of the 44-pin “D” connector on the
ECI-44. Also, the shield connection points of the ECI-44 are also designed to provide a
point for cable strain relief.

Use tie wraps to provide a strain relief and a ground connection at the shield connection
points.

If you do not wish to use the DIN rail mounting hardware, the ECI-44 can be disassembled
and the mounting clips removed.

The ECI-44 wire range is #18 to 24 AWG stranded insulated wire.

Note

Power Dissipation

In general, the drive power stages are 90 to 95 percent efficient depending on the actual point
of the torque speed curve the drive is operating. Logic power losses on the Epsilon drive are
11 W with normal loads to 15 W with additional loads such as external encoder and low input
voltage (<22 VDC on A.P.S. or 120 VAC on AC input).

The values shown in the table below represent the typical dissipation that could occur with
the drive/motor combination specified at maximum output power.

Power Dissipation Calculation

Calculating actual dissipation requirements in an application can help minimize enclosure
cooling requirements, especially in multi-axis systems. To calculate dissipation in a specific
application, use the following formula for each axis and then total them up. This formula is a
generalization and will result in a conservative estimate for power losses.

Where:

52

TPL ++=

Vmax * TRMS

Psr Pld

1500

TPL = Total power losses (Watts)
TRMS = RMS torque for the application (lb-in)
Vmax = Maximum motor speed in application (RPM)
Pld = Logic Power Losses Drive (Watts)
Psr = Shunt Regulation Losses (Watts)-(RSR-2 losses or equivalent)

Note

TRMS * Vmax / 1500 = Power Stage Dissipation = Pp

A more accurate calculation would include even more specifics such as actual torque
delivered at each speed plus actual shunt regulator usage. For help in calculating these please
contact our Application Engineering department with your system profiles and loads.

Speed Torque Curves

Continuous ratings of the MG and NT motors are based on 100°C (212° F) motor case
temperature and 25°C (77° F) ambient temperature with the motor mounted to an aluminum
mounting plate as shown in the table below.

Motor Mounting Plate Size

MG-205 and 208, NT-207 and 212 6” x 6” x .25”

MG-316 through 490 10” x 10” x .375

MG-4120 12” x 16” x .5”

Specifications

• Speed torque curves are based on 240 VAC drive operation.

• All specifications are ±5 percent due to motor parameter variations.
