Caution:
Falcon Installation Guide
In order to achieve the optimum, safe operation of the Falcon servo drive, it is imperative that
you implement the safety procedures included in this installation guide. This information is
provided to protect you and to keep your work area safe when operating the Falcon and
accompanying equipment.
Please read this chapter carefully before you begin the installation process.
Before you start, ensure that all system components are connected to earth ground. Electrical
safety is provided through a low-resistance earth connection.
Only qualified personnel may install, adjust, maintain and repair the servo drive. A “qualified
person” has the knowledge and authorization to perform tasks such as transporting,
assembling, installing, commissioning and operating motors.
The Falcon servo drive contains electrostatic-sensitive components that can be damaged if
handled incorrectly. To prevent any electrostatic damage, avoid contact with highly insulating
materials, such as plastic film and synthetic fabrics. Place the product on a conductive surface
and ground yourself in order to discharge any possible static electricity build-up.
7
To avoid any potential hazards that may cause severe personal injury or damage to the product
during operation, keep all covers and cabinet doors shut.
The following safety symbols are used in this manual:

Falcon Installation GuideSafety Information
1.1. Warnings
• To avoid electric arcing and hazards to personnel and electrical contacts, never
connect/disconnect the servo drive while the power source is on.
• Power cables can carry a high voltage, even when the motor is not in motion. Disconnect
the Falcon from all voltage sources before it is opened for servicing.
• After shutting off the power and removing the power source from your equipment, wait at
least 1 minute before touching or disconnecting parts of the equipment that are normally
loaded with electrical charges (such as capacitors or contacts). Measuring the electrical
contact points with a meter, before touching the equipment, is recommended.
1.2. Cautions
• The Falcon servo drive contains hot surfaces and electrically-charged components during
operation.
• The maximum DC power supply connected to the instrument must comply with the
parameters outlined in this guide.
8
• The Falcon can operate only through an isolated power source, using an isolated
transformer and a rectifier circuit. Power to this device must be supplied by DC voltage,
within the boundaries specified for the Falcon. High voltages may damage the drive.
The DC power supply voltage range is defined in the table in Section 4.3.
Safety margins must be considered in order to avoid activating the under- or over-voltage
protection against line variations and/or voltage drop under load. The transformer should
be able to deliver the required power to the drive (including peak power) without
significant voltage drops (10% maximum). While driving high-inertia loads, the power
supply circuit must be equipped with a shunt regulator; otherwise, the drive will be
disabled whenever the capacitors are charged above the maximum voltage.
• Before switching on the Falcon, verify that all safety precautions have been observed and
that the installation procedures in this manual have been followed.
• Do not clean any of the Falcon drive's soldering with solvent cleaning fluids of pH greater
than 7 (8 to 14). The solvent corrodes the plastic cover causing cracks and eventual damage
to the drive's PCBs.
Elmo recommends using the cleaning fluid Vigon-EFM which is pH Neutral (7).

2.2. Drive Description
The Falcon is a series of highly durable and intelligent servo drives. Designed for OEMs, the
Falcon is part of the Elmo’s ExtrIQ product line designed to endure extended environmental
operating conditions.
The digital drives are based on Elmo's advanced ExtrIQ 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 Falcon can operate as a stand-alone device or as part of
a multi-axis system in a distributed configuration on a real-time network.
The Falcon drive is set up and tuned using Elmo’s Composer software. This Windows-based
application enables users to quickly and simply configure the servo drive for optimal use with
their motor.
Power to the Falcon is provided by a 10 to 195 VDC source. A smart control-supply algorithm
enables the Falcon to operate with the power supply only, with no need for an auxiliary 24 Volt supply. If backup functionality is required for storing control parameters in case of power-outs,
an external 24 VDC power supply can be connected, providing maximum flexibility and optional
backup functionality when needed.

MAN-FALIG (Ve r. 1.502)
Falcon Installation Guide Installation
3.4. Connecting the Cables
The Falcon has ten connectors.
3.4.1. Wiring the Falcon
Once the Falcon 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 Falcon.
Caution:
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.
21
• 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.

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 Falcon.
• Be sure that the motor chassis is properly grounded.

Notes for connecting the DC power supply:
25
• Be sure to isolate the source of the 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 Falcon’s heatsink.
• For safety reasons connect the PR of the power supply to the closest ground connection.

Page 26
MAN-FALIG (Ve r. 1.502)
Falcon Installation Guide Installation
3.4.3. Connecting the Optional Backup Supply Cable (24 V)
Power to the Falcon is provided by a 10 to 195 VDC source. A “smart” control-supply algorithm
enables the Falcon to operate with the power supply only, with no need for an auxiliary 24 volt supply. If backup functionality is required for storing control parameters in case of power-outs,
an external 24 VDC power supply (13 Vmin to 40 Vmax) can be connected, providing maximum
flexibility and optional backup functionality when needed.
To connect the backup supply to the 24v port on the bottom of the Falcon, use the 2-pin power
plug provided with the Falcon. Remember, you are working with DC power; be sure to exercise caution. The required voltage is 24 VDC.
Notes for 24 VDC backup supply connections:
• Use a 24 AWG twisted pair shielded cable. The shield should have copper braid.
• The source of the 24 VDC must be isolated.
• For safety reasons, connect the return of the 24 VDC source to the closest ground.
• Connect the cable shield to the closest ground near the 24 VDC source.
26
• Before applying power, first verify the polarity of the connection.

shut off.
3.4.4. Feedback and Control Cable Assemblies
The Falcon features easy-to-use D-Sub type connections for all Control and Feedback cables.
Instructions and diagrams describing how to assemble those cables are presented below.
1. 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.
2. Use only a D-Sub connector with a metal housing.
3. Ideally, solder the drain wire to the connector body as shown in Figure 8.
However, the shield may also be attached without soldering, as long as the braid shield is in
tight contact with the metal housing of the D-type connector.

3.4.9. Communication Cables
The communication cables use an 8-pin RJ-45 plug that connect to the RS-232 and CAN ports
on the “top” of the Falcon.
The communication interface may differ according to the user’s hardware. The Falcon can
communicate using the following options:
a. RS-232, full duplex
b. CAN
RS-232 communication requires a standard, commercial 3-core null-modem cable connected
from the Falcon to a serial interface on the PC. The interface is selected and set up in the
Composer software.
In order to benefit from CAN communication, the user must have an understanding of the basic
programming and timing issues of a CAN network. The interface is electrically isolated by
optocouplers.
For ease of setup and diagnostics of CAN communication, RS-232 and CAN can be used
simultaneously.
51
3.4.9.1. RS-232 Communication
Notes for connecting the RS-232 communication cable:
• Use a 26 or 28 AWG twisted pair shielded cable. 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.
• The male RJ plug must have a shield cover.
• Ensure that the shield of the cable is connected to the shield of the RJ plug. The drain wire
can be used to facilitate the connection.

3.5. Powering Up
After the Falcon has been mounted, check that the cables are intact. The Falcon 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 Falcon and that the proper plus-minus connections are
in order.
3.6. Initializing the System
After the Falcon 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
ComposerSoftware Manual.
