Glossary
Term Denition
Accuracy See Measurement Uncertainty.
ADC Analog-to-digital converter.
Calibration The act of measuring a transducer’s raw response to loads and
creating data used in converting the response to forces and torques.
Calibration Certicate
A statement that says the equipment measures correctly. These
statements mean the equipment has been tested against national
standards. The statements are produced as a result of calibration or
re-calibration.
CoE CANopen over EtherCAT is the preferred embedded protocol for conguring EtherCAT devices. Used within SDO to encode the
conguration data.
Compound Loading Any load that is not purely in one axis.
Coordinate Frame See point of origin.
DINT A 32-bit data type representing a signed integer.
DoF Degrees of freedom. See six degrees of freedom.
EtherCAT An industrial automation eldbus.
FoE File access over EtherCAT, the preferred embedded protocol for
uploading new rmware to EtherCAT devices.
Force The push or pull exerted on an object.
FS Full-Scale.
F/T Force/Torque.
F/T Transducer The device that converts force and torque into an electrical signal.
Fxy The resultant force vector comprised of components Fx and Fy.
Full-Scale Error
A measurement of sensing error. For example, if the calibrated
measurement range of a sensor is 100 Newtons and the sensor is
accurate to within 1 Newton, that sensor will have a Full-Scale Error of
1% (1% = 0.01 = 1 N / 100 N).
Hysteresis A source of measurement error caused by the residual effects of
previously applied loads.
IP60 Ingress protection rating “60” designates protection against dust.
ISR Interrupt service routine.
MAP The Mounting Adapter Plate (MAP) is the transducer plate that attaches
to the xed surface or robot arm.
MAX. Single-Axis Overload The largest amount of load in a single axis (all other axes are unloaded)
that the transducer can withstand without damage.
Measurement Uncertainty The maximum expected error in measurements, as specied on the
calibration certicate.
Moment An object that receives a torque has a moment applied to that object.
Offset Compensation Correction of errors that change the zero point of a transducer’s
readings.
Overload The condition where more load is applied to the transducer. This will
result in saturation.
PDO Process Data Object, a protocol for reading and writing real-time
process information cyclically.

Term Denition
Point of Origin The point from which the transducer measures all forces and torques.
Quantization The way the continuously variable transducer signal is converted into discrete digital values. Usually used when describing the change from
one digital value to the next.
RAM Random access memory.
Reaction Torque Torque applied that does not result in movement. For example, if a user twists a screw or bolt but the fastener does not move. ATI transducers
sense reaction torque.
Re-Calibration The periodic verication of measurement equipment, like transducers, calipers, and voltmeters, to prove it still measures correctly. The
equipment may be adjusted if it doesn’t measure correctly.
Resolution The smallest change in load that can be measured. This is usually
much smaller than accuracy.
Rotary Torque Torque resulting in something moving. Generally this refers to the torque on things like drive shafts. ATI transducers cannot sense
rotational torque.

1. Safety
The safety section describes general safety guidelines for the product(s), an explanation of the notications found
in this manual, and the safety precautions applicable to the product(s). More specic notications are embedded
within the sections of the manual where they apply.
1.1 ExplanationofNotications
The notications included here are specic to the product(s) covered by this manual. The user should heed
all notications from the robot manufacturer and/or the manufacturers of other components used in the
installation.
DANGER: Notication of information or instructions that if not followed will result in
death or serious injury. The notication provides information about the nature of the
hazardous situation, the consequences of not avoiding the hazard, and the method for
avoiding the situation.
WARNING: Notication of information or instructions that if not followed could result
in death or serious injury. The notication provides information about the nature of the
hazardous situation, the consequences of not avoiding the hazard, and the method for
avoiding the situation.
CAUTION: Notication of information or instructions that if not followed could result in
moderate injury or cause damage to equipment. The notication provides information
about the nature of the hazardous situation, the consequences of not avoiding the
hazard, and the method for avoiding the situation.
NOTICE: Notication of specic information or instructions about maintaining, operating,
installation, or setup of the product that if not followed could result in damage to equipment. The
notication can emphasize but is not limited to specic grease types, good operating practices,
or maintenance tips.
1.2 General Safety Guidelines
The customer should verify that the transducer selected is rated for maximum loads and torques expected
during operation. Because static forces are less than the dynamic forces from the acceleration or declaration
of the robot, be aware of the dynamic loads caused by the robot.

1.3 Safety Precautions
WARNING: Performing maintenance or repair on the sensor, while circuits (e.g. power,
water, and air) are energized could result in serious injury. Discharge and verify all
energized circuits are de-energized in accordance with the customer’s safety practices
and policies.
CAUTION: Modifying or disassembly of the sensor could cause damage and void the
warranty. Use the supplied mounting adapter plate 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: Probing openings in the sensor causes damage to the instrumentation.
Avoid prying into openings of the transducer.
CAUTION: Do not overload the transducer. Exceeding the single-axis overload values
of the transducer, causes irreparable damage.
CAUTION: Do not contact the IP60 seal. Contacting the seal can cause the sensor to
malfunction.
CAUTION: The sensor should be protected from impact and shock loads that exceed
rated ranges during transport as the impacts can damage the sensor’s performance.
Refer to Section8—Specications for more information about rated ranges.
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.
