3. Installation
WARNING: Performing maintenance or repair on the sensor when circuits (e.g. power,
water, and air) are energized could result in death or serious injury. Discharge and verify all
energized circuits are de-energized in accordance with the customer’s safety practices and
policies.
CAUTION: Modication or disassembly of the sensor could cause damage and void the
warranty. Use the supplied mounting bolt pattern and the provided tool side mounting
bolt pattern to mount the sensor to the robot and customer tooling to the sensor. Refer to
Section 9—Drawings for more information.
CAUTION: Using fasteners that exceed the customer interface depth penetrates the body of
the sensor, damages the electronics, and voids the warranty. Refer to Section 9—Drawings
for more information.
CAUTION: Thread locker applied to fasteners must not be used more than once. Fasteners
may become loose and cause equipment damage. Always apply new thread locker when
reusing fasteners.
CAUTION: Avoid damage to the sensor from Electro-Static Discharge. Ensure proper
grounding procedures are followed when handling the sensor or cables connected to the
sensor. Failure to follow proper grounding procedures could damage the sensor.
CAUTION: Do not apply excessive force to the sensor and cable connector during
installation, or damage will occur to the connectors. Align the keyway on the sensor and cable
connector during installation to avoid applying excessive force to the connectors.
Keyway on the
cable connector.
Keyway on the
sensor connector.
NOTICE: Depending on the maintenance or repair being performed, utilities to the sensor may not
need to be disconnected.
3.1 Adapter Plates
The sensor’s mounting side attaches to the robot arm, and the sensor’s tool side attaches to the customer
tooling. If adapter plate(s) are required to interface the sensor to the robot arm and customer tooling, ATI
can supply custom robot and tool adapter plates. Refer to Section 9—Drawings of this manual for technical
information on the sensor’s mounting features.
CAUTION: Incorrect installation of robot mounting and tool adapter plates will result in
the failure of the F/T sensor to function properly. Because the mounting and tool sides
of the sensor have identical bolt patterns, verify the robot mounting and tool adapter
plates are installed correctly.
CAUTION: The customer tool should only touch the tool adapter plate. If the customer
tool touches any other part of the sensor, it will not properly sense loads.

If the customer chooses to design and build an adapter plate(s), the following points should be considered:
• The adapter plate(s) should include bolt holes for mounting fasteners as well as dowel pin(s) and a
boss for accurate positioning to the robot or customer’s device.
• The thickness of the adapter plate(s) must provide sufcient thread engagement for the mounting
fasteners.
• The mounting fasteners should not extend through the sensor’s housing or interfere with the internal
electronics. Refer to Section 9—Drawings for thread depth, mounting patterns, and other details.
• Do not use dowel pin(s) that exceed length requirements and prevent the adapter plate(s) from
mating ush with the robot and customer tooling. Fasteners that exceed length requirements create
a gap between the interfacing surfaces and cause damage.
• The adapter plate(s) must not distort from the maximum force and torque values that can be applied
to the sensor. For these values, refer to Section8—Specications.
• The adapter plate(s) must provide a at and parallel mounting surface for the sensor.

3.2 Routing the Cable
The routing and bending radius of the cable depends upon the customer application. Unlike motionless
applications, where the cable is in a static condition, dynamic applications subject the cable to a repetitive
motion. For dynamic applications, restrain the cable at a distance that does not expose and damage the
sensor’s cable connection from the robot’s repetitive motion.
NOTICE: The maximum supported cable length is 25 m.
Figure 3.2—Routing of the Sensor Cable
Sensor Cable
Restrain cable to keep
repetitive motion from
affecting the cable
connection.
Robot Arm
Allow enough slack in
the cable to allow full range
of motion for the robot device.
F/T Sensor
Mounting
Adapter Plate
CAUTION: Do not subject the sensor’s cable connector to the repetitive motion
of the robot or other device. Subjecting the connector to the repetitive motion will
cause damage to the connector. Restrain the cable close to the connector so that the
repetitive motion of the robot does not interfere with the cable connector.
CAUTION: The cable must withstand the repetitive motions of the robot without failing.
The electrical line, especially where attached to the sensor’s connector, must be routed
to avoid stress failure, sharp bends, or a disconnection from the equipment. Improper
routing may cause poor functionality of critical electrical lines, injury to personnel, or
damage to equipment. Damage to the sensor or cable from improper routing will void
the warranty. If the application results in cable rubbing, use a loose, plastic spiral wrap
for protection.
CAUTION: When routing cables do not bend less than the minimum bending radius
specied in Table 3.1. A bend radius too small causes the cable to fail from fatigue of
the robot’s repetitive motion.

EtherCAT cable, of which branch 1 is an unterminated end for connection to power and branch 2 has a RJ45
connection for EtherCAT.
Route the sensor cable so that it is not stressed, pulled, kinked, cut, or otherwise damaged throughout the
full range of motion. If the application causes cable abrasion, use a loose plastic, spiral wrap to protect the
outer cable jacket material.
CAUTION: Do not damage or crush the cable by over tightening tie wraps on the cable.
3.3 Installing the Sensor to the Robot

3.6 Accuracy Check Procedure
Complete the following procedures after the initial installation of the sensor to the robot and once annually
for maintenance.
1. Attach a xed mass to the tool side of the F/T sensor.
• The mass on the tool side can be the weight of the tooling used in an application.
a. Remove cables that form bridges between the sensor’s mounting and tool sides.
2. Move the robot so that the sensor is in the following positions.
a. Record the sensor’s output, Fx Fy Fz, at each point without biasing.
• Point 1: +Z up
• Point 2: +X up
• Point 3: +Y up
• Point 4: -X up
• Point 5: -Y up
• Point 6: -Z up
3. Find Fx, average , Fy, average , and Fz, average.
a. Perform the following equations.
4. For each of the 6 points, complete the following calculation:
5. Once the tooling mass has been calculated for all (6) points, the range of the tooling masses should be
less than twice the worst accuracy rating of the sensor.
• le max (tooling masses) - min(tooling masses) < 36 N
• In addition, the tooling mass should be within 36 N of the results of this test when it was
performed with a new sensor.
• If this test fails, then the sensor should be returned to ATI for diagnosis or recalibration.

4. Operation
The following section provides information required when using software to operate the EtherCAT Sensor.
Communicating with the EtherCAT sensor requires knowledge of EtherCAT standards and operation.
4.1 Sensor Environment
CAUTION: Damage to the outer jacketing of the transducer cable could enable
moisture or water to enter an otherwise sealed transducer. Ensure the cable jacketing
is in good condition to prevent transducer damage.
NOTICE: Transducers may react to exceptionally strong and changing electromagnetic elds,
such as those produced by magnetic resonance imaging (MRI) machines.
To ensure proper operation, the IP60 rating of the sensor must match or exceed the transducer’s
environment.
4.2 Sample Rate
The “Sample Rate” eld in Section 5.2.8—Object 0x7010: Control Codes controls the current sample rate.
The following table lists the rounded and exact sample rates.
Table 4.1—Sample Rate
Rounded Sample Rate 0.5 kHz 1 kHz 2 kHz 4 kHz
Exact Sample Rate 487 Hz 975 Hz 1990 Hz 3900 Hz
4.3 Low-pass Filter
The power-on default selection is no ltering. The “Filter Selection” eld in Section 5.2.8—Object 0x7010:
Control Codes controls the current lter selection. The cutoff frequency (i.e. -3 dB frequency) is dependent
on the sample rate selection, which is dened in Section 4.2—Sample Rate. The cutoff frequencies for the
different sampling rates are listed in the following table and graphs:
