Chapter 2: Introduction
This installation guide descri bes t he Drum ser vo d riv es and t he steps for i ts wi ri ng,
installation and power-up. Following these guidelines ensures maximum functionality of
the drive and the system to which it is connected.
2.1 Drive Description
The Drum series are highly resilient digital servo drives designed to deliver “the highest
density of power and intelligence”. The Drum delivers up to 9.6 kW of continuous
power or 11.2 kW of peak power in a compact package.
The digital drives are based on Elmo’s advanced SimplIQ motion control technology.
They operate from a DC power source in current, velocity, position and advanced position
modes, in conjunction with a permanent-magnet synchronous brushless motor, DC brush
motor, linear motor or voice coil. They are designed for use with any type of sinusoidal and
trapezoidal commutation, with vector control. The Drum can operate as a stand-alone
device or as part of a multi-axis system in a distributed configuration on a real-time
network.
2-1
The drives are easily set up and tuned using Elmo’s Composer software tools. This
Windows-based application enables users to quickly and simply configure the servo drive
for optimal use with their motor. The Drum, as part of the
programmable with Elmo Metronome motion control language.
Power to the drives is provided by a 12 ~ 195 VDC isolated DC power source (not included
with the Drum). The power stage is fully isolated from the control stage. A “smart”
control-supply algorithm enables the Drum to operate with only one power supply with no
need for an auxiliary power supply for the logic.
If back-up functionality is required for storing control parameters in case of power-loss, an
external 12 ~ 195 VDC isolated supply should be connected (via the CAN connector on the
Drum) providing maximum flexibility and backup functionality when needed.
Note: This back-up functionality can operate from any voltage source within the
12 ~ 195 VDC range. This is much more flexible than to be restricted by only using a
standard 24 VDC power supply.
If back-up power is not needed, then the main power supply will also power the
control/logic supply. In this way there is no need for a separate control/logic supply.

3.4 Connecting the Cables
3.4.1 Wiring the Drum
Once the Drum is mounted, you are ready to wire the device. Proper wiring, grounding and
shielding are essential for ensuring safe, immune and optimal servo performance of the
Drum.
Follow these instructions to ensure safe and proper wiring:
Use twisted pair shielded cables for control, feedback and communication connections.
For best results, the cable should have an aluminum foil shield covered by copper braid,
and should contain a drain wire.
The drain wire is a non-insulated wire that is in contact with parts of the cable,
usually the shield. It is used to terminate the shield and as a grounding connection.
The impedance of the wire must be as low as possible. The size of the wire must be thicker
than actually required by the carrying current. A 24, 26 or 28 AWG wire for control and
feedback cables is satisfactory although 24 AWG is recommended.
Use shielded wires for motor connections as well. If the wires are long, ensure that the
capacitance between the wires is not too high: C < 30 nF is satisfactory for most
applications.
Keep all wires and cables as short as possible.
Keep the motor wires as far away as possible from the feedback, control and
communication cables.
Ensure that in normal operating conditions, the shielded wires and drain carry no current.
The only time these conductors carry current is under abnormal conditions, when
electrical equipment has become a potential shock or fire hazard while conducting
external EMI interferences directly to ground, in order to prevent them from affecting the
drive. Failing to meet this requirement can result in drive/controller/host failure.
After completing the wiring, carefully inspect all wires to ensure tightness, good solder
joints and general safety.

3.4.2.1 Connecting the Motor Cable
Connect the motor power cable to the M1, M2, and M3 terminals of the main power connector
and the fourth wire to the PE (Protective Earth) on the heat sink (see diagram above). The
phase connection order is arbitrary because the Composer will establish the proper
commutation automatically during setup.
Notes for connecting the motor cables:
For best immunity, it is highly recommended to use a shielded (not twisted) cable for
the motor connection. A 4-wire shielded cable should be used. The gauge is
determined by the actual current consumption of the motor.
Connect the shield of the cable to the closest ground connection at the motor end.
Connect the shield of the cable to the PE terminal on the Drum.
Be sure that the motor chassis is properly grounded.
To close the motor cable into the drive, use the barrel connector, M6 spring washer
and M6 nut (in the drive). The required torque is 3-4 Nm.
To close the PE wire into the drive, use the barrel connector, M5 flat washer, M5
spring washer and M5 screw to the heatsink. The required torque is 3-4 Nm.
3-10
Figure 3-3: AC Motor Power Connection Diagram
3.4.2.2 Connecting the DC Power
The Power stage of the Drum is fully isolated from other sections of the Drum, such as the
control stage and the heatsink. This contributes very significantly to the safety and the EMI
immunity of the Drum. In addition it simplifies the requirements of the DC power supply
used to power the DC bus of the Drum and allows also the operation with a non-isolated DC
power source.
Operation with an Isolated DC power Supply:
The PE (Protective Ground of the AC network) is connected to the PR terminal [The negative
power terminal (-)].

Notes for connecting the DC power supply:
Be aware: The Drum can operate from either an:
o isolated DC power supply
or
o non-isolated DC power supply
For best immunity, it is highly recommended to use twisted cables for the DC power
supply cable. A 3-wire shielded cable should be used. The gauge is determined by
the actual current consumption of the motor.
Connect both ends of the cable shield to the closest ground connection, one end near
the power supply and the other end to the PE terminal on the Drum’s heatsink.
For safety reasons connect the PR of the power supply to the closest ground
connection.
To close the power supply cable into the drive, use the barrel connector, M6 spring
washer and M6 nut (in the drive). The required torque is 3-4 Nm.
To close the PE wire into the drive, use the barrel connector, M5 flat washer, M5
spring washer and M5 screw to the heatsink. The required torque is 3-4 Nm.

3.4.2.3 Connecting the Optional Back-up Supply Cable
Power to the Drum is provided by a 12 to 195 VDC source (depending on model type). A
“smart” control-supply algorithm enables the Drum to operate with the power supply only,
with no need for an auxiliary supply voltage. If backup functionality is required for storing
control parameters in case of power-outs, an external 12-195 VDC power supply can be
connected, providing maximum flexibility and optional backup functionality when needed.
To connect the back-up supply to the Auxiliary port, use the Drum's J1 connector (CAN
communication connector). Remember, you are working with DC power so be sure to exercise
caution.
Notes for back-up supply connections:
Use a 24 AWG twisted pair shielded cable. The shield should have copper braid.
The source of the back-up supply must be isolated.
For safety reasons, connect the return of
ground.
Connect the cable shield to the closest ground near the power source.
Before applying power, first verify the polarity of the connection.

3.4.3 Feedback Control and Communication Cable Assemblies
The Drum features easy-to-use D-sub type connections for all Control and Feedback cables.
Below are instructions and diagrams describing how to assemble those cables.
Use 24, 26 or 28 AWG twisted-pair shielded cables (24 AWG cable is recommended).
For best results, the shield should have aluminum foil covered by copper braid.
Drum Installation G uide Installation
MAN-DRUIG (Ver. 1.0)
Use only a D-sub connector with a metal housing.
Attach the braid shield tightly to the metal housing of the D-type connector.
On the motor side connections, ground the shield to the motor chassis.
On controller side connections, follow the controller manufacturer’s
recommendations concerning the shield.
Metal Housing
Make sure that the braid shield is in
tight contact with the metal housing
3-15
Figure 3-9: Feedback and Control Cable A ssemblies
Note: All D-sub type connectors, used with the Drum, should be assembled in this way.
3.4.4 Main Feedback Cable (FEEDBACK A)
The main feedback cable is used to transfer feedback data from the motor to the drive.
The Drum accepts the following as a main feedback mechanism:
Incremental encoder only
Incremental encoder with digital Hall sensors
Digital Hall sensors only
Incremental Analog (Sine/Cosine) encoder (option)
Resolver (option)
Tachometer & Potentiometer
Absolute Encoder
FEEDBACK A on the “front” of the Drum has a 26-pin high density D-sub socket. Connect the
Main Feedback cable from the motor to FEEDBACK A using a 26-pin, high density D-Sub
plug with a metal housing. When assembling the Main Feedback cable, follow the instructions
in Section
3.4.3 (Feedback Control and Communication Cable Assemblies).
Note: the Feedback connector also support s Feedbacks A and B.

3.4.8 Communication Cables
The communication cables use a 9-pin D-sub plug that connect to the RS-232 and 9-pin D-sub
socket that connects to the CANopen ports on the Drum.
The communication interface may differ according to the user’s hardware. The Drum can
communicate using the following options:
a. RS-232, full duplex
b. CANopen
RS-232 communication requires a standard, commercial 3-core null-modem cable connected
from the Drum to a serial interface on the PC. The interface is selected and set up in the
Composer software.
In order to benefit from CANopen communication, the user must have an understanding of
the basic programming and timing issues of a CANopen network. The interface is electrically
isolated by optocouplers.
For ease of setup and diagnostics of CAN communication, RS-232 and CANopen can be used
simultaneously.
3-42
3.4.8.1 RS-232 Communication
Notes for connecting the RS-232 communication cable:
Use a 24, 26 or 28 AWG twisted pair shielded cable (24 AWG cable is recommended).
The shield should have aluminum foil covered by copper braid with a drain wire.
Connect the shield to the ground of the host (PC). Usually, this connection is
soldered internally inside the connector at the PC end. You can use the drain wire to
facilitate connection.
Use only a D-sub connector with a metal housing.
Attach the braided shield tightly to the metal housing of the D-type connector.
When assembling the Communication cable, follow the instructions in Section
(Feedback Control and Communication Cable Assemblies).

3.5 DC Power Supply
The DC power supply can be at any voltage in the range defined in the technical
specifications (the Appendix of this guide). The supply source must comply with the safety
aspects of the relevant requirements, in accordance with the most recent version of the
standard EN60950 or equivalent Low Voltage Directive Standard, all according to the
applicable over-voltage category. If the power source to the power supply is the AC line
(through an isolated or a non-isolated transformer), safety margins must be considered, in
order to avoid activating the under/over voltage protection due to line variations and/or
voltage drop under load.
In addition to the above, the transformer must comply with the safety aspects of the relevant
requirements in accordance with the most recent version of the standard EN60742 (Isolating
and Safety Isolating Transformers). The nominal DC bus voltage should be in the following
range:
3-45
1.2 V
< Vdc < 0.9 V
dcmin
dcmax
Where:
V
is the minimum DC bus
dcmin
is the maximum DC bus
V
dcmax
The transformer power should be calculated such that it will be able to deliver power to the
amplifier (including peak power) without significant voltage drops.
The power supply should be located as close as possible to the amplifier. While driving highinertia loads, the power supply must be equipped with a shunt regulator; otherwise, the
amplifier will be disabled whenever the capacitors are charged above the maximum voltage,
during motor break down.
3.5.1 Powering Up
After the Drum has been mounted, check that the cables are intact. The Drum servo drive is
then ready to be powered up.
Caution:
Before applying power, ensure that the DC supply is within the range
specified for your specific type of Drum and that the proper
plus-minus connections are in order.
3.5.2 Initializing the System
After the Drum has been connected and mounted, the system must be set up and initialized.
This is accomplished using the Composer, Elmo’s Windows-based software application. Install
the application and then perform setup and initialization according to the directions in the
Composer Software Manual.

3.6 Heat Dissipation
For full power output capability the Drum is designed to be mounted on an external heatsink.
It is highly recommended that the “Wall” on which the Drum is mounted will have heat
dissipation capabilities. The Drum at “free air convection” (without an additional heatsink)
can dissipate around 12 W for 40 °C ambient temperature and not exceeding 80 °C on the
heatsink.
When “Free Air Convection” is sufficient for the application it is recommended to leave
approximately 10 mm of space between the Drum's heatsink and any other assembly.
3.6.1 Drum Thermal Data
• Free air convection thermal resistance (θ): Approximately 3.6 – 4 °C/W.
• Thermal time constant: Approximately 40 minutes/ 2400 seconds (thermal time
constant means that the Drum will reach 2/3 of its final temperature after 4 minutes).
• Self heat dissipation capability (no external heatsink): 12W for 40 °C/W temperature
rise.
• Shut-off temperature: 86 °C – 88 °C (measured on the heatsink).
• The thermal resistance when connecting to an external heat sink:
o The surface of the external heatsink is 50um: 0.18 °C/W.
o Thermal conductive compound. By proper Smearing of the surface a
significant improvement of the thermal resistance is achieved: 0.13 °C/W

3.6.3 How to Use the Charts
The charts above are based upon theoretical worst-case conditions. Actual test results show
30% - 50% better power dissipation.
To determine if your application needs a heatsink:
1. Allow maximum heatsink temperature to be 80°C or less (shunt down is 6 °C – 8 °C
higher).
2. Determine the ambient operating temperature of the Drum as ≤ 40 °C.
3. Calculate the allowable temperature increase as follows:
• for an ambient temperature of 40°C , ∆T= 80 ° C – 40 °C = 40 °C
4. Use the chart to find the actual dissipation power of the drive. Follow the voltage
curve to the desired output current and then find the dissipated power.
5. If the dissipated power is below 12 W the Drum needs no additional cooling.
Note: The chart above shows that no heatsink is needed when the heatsink temperature is
80 °C, ambient temperature is 40 °C and heat dissipated is 4 W.
