General wiring standards
To achieve reliable operation of the UCC T5 and the CMM's host computer, the following points should be observed:
All signal cables MUST be screened and all cable screens must be connected electrically to the metal shells of the cable connectors
It is recommended that cable screens should only be connected to the protective earth (via the connector shell) of the UCC T5 and
SPA3
To avoid earth loops, cable screens should not be directly attached to the CMM's protective earth
The protective grounding must be continuous between the controller and all other equipment in the installation
All cable connectors should be secured to the UCC T5 and SPA3 by the connector jack screws
NOTE: The UCC T5 and SPA3 electronic zero volt rails are connected to their respective ground planes at star points within the
UCC T5, the SPA3 and also to the protective ground of the ac supply.

Connecting the UCC T5 to the host PC
Hardware connection
The host PC must have a dedicated ethernet connection to the UCC T5. It is recommended that this is not a USB plug-in adapter
because of the reduction in speed these devices normally produce.
If the host PC is connected to a network, it is necessary to install additional hardware to allow a dedicated connection for UCC T5
communication. For details on how to install additional hardware on the host PC, please refer to the manufacturer user's guide.
The UCC T5 is capable of using 1 Gbps ethernet (with appropriate cable). .
A 5 m ethernet cable is provided for this link as part of the UCC T5 kit. The cable included is a Cat 5E, cross-over type. Other lengths may
be used, but the maximum length is determined by the generic specification for ethernet connections which are sufficient for any CMM
installation.
It is recommended that a shielded cross-over cable is used if there is a likelihood of EMC disruption due to the environment or location of
the routed cable.
It is recommended that the cross-over cable is labelled to avoid being mistaken for a non cross-over cable.
Software installation
UCCsuite 4.7 or newer software must be installed on the host PC prior to connection of the UCC T5. The UCC software suite can be
downloaded from the Renishaw website. After the software has been installed, run UCCassist-2 to set up and configure the CMM
controller.

Sensor resistance checks
A resistance check test is recommended:
During system installation once all sensor cabling has been completed
After every hardware change to the system (e.g. sensor, cable or switch change)
Every six months, after the system has been commissioned, to check for any sensor failure or cabling issues
Resistance check procedure
RegulatethetemperatureoftheCMMroomtoaconstanttemperaturebetween16°Cand28°C
Allow the CMM to stabilise thermally for a minimum of one hour
Measure the sensor resistance from the 37-way D-type socket that the sensors are wired into. This is the resistance that the UCC
measures (cable plus sensor resistance).
Allworkpieceandaxissensorresistancemeasurementsshouldbewithinthisrange;8.4kΩ<R<15.7kΩ
Best practise for using the thermal compensation system
Ensure the CMM is not subjected to unnecessary changes in temperature (fans blowing, close to radiator, in direct sunlight or any other
powerful radiant sources)
Excessive humidity should be avoided
Use the system as close as possible to the calibrated temperature
Renishaw recommends that workpiece and axis sensors are verified at six month intervals

Page 25
Workpiece sensor
Ensure the workpiece sensor is in full contact with the workpiece
Aim to position the workpiece sensor in the middle of the workpiece or near where the measurement is taking place
Electrically ground workpiece prior to using the thermal effect compensation system to avoid electrostatic discharge (ESD) through the
workpiece sensor
Use multiple sensors for large workpieces
Handle the workpiece sensor by the white sleeve if possible or wait for five minutes once the sensor is in position before proceeding to
take a measurement
Keep the workpiece sensor cabling away from moving sections of the CMM
NOTE: It is not recommended to run axis thermal compensation without workpiece compensation (where axes and workpiece are at
the same temperature) as it is unlikely that reliable results will be obtained.
Axis sensors
Ensure the sensors are mounted as close as possible to the axis scales
It is recommended to have at least two sensors per axis to account for temperature gradient effects
On large or high specification CMMs, use more than three sensors per axis
Thermally conductive glue should be used when gluing axis sensors to an axis
All axis sensor cabling must be tightly secured to the axis body to prevent it getting trapped during moves

Fatal faults
Situations can occur that make it inadvisable or dangerous to continue using the CMM servo system. These are known in this document
and UCCassist-2 as fatal faults. A list of fatal faults are shown below and will be indicated through the user's software (for example
UCCserver);
A report of the emergency stop switch being active
Air pressure is too low
Crash switch operated, if fitted
A scale reading failure
An indicated overspeed (calculated from the rate of change of position)
Outer limit switch active
NOTE: Other faults not classed as fatal can prevent the CMM's operation.
Motors will not engage / re-engage
Symptoms
Eithertheservodriveswillnotengagewhenthecontrollerhasbeensentthe‘engage'command,orthedriveshavedisengaged
automatically and will not re-engage.
Possible causes (or reported causes)
After the unit is switched on and before the system is allowed to engage, it must be configured for motion (i.e. the machine, servo and
move parameters must be sent to the controller).
Any of the 'fatal faults' will prevent the system from engaging. In addition, the following will disengage the servo motors;
A reported failure from a servo power amplifier (amplifier feedback signal)
The absence of the feedback signal from the motor contactor
The following list can also inhibit drive engagement or re-engagement
The probe being deflected
Any outer limit switch being operated or a soft limit exceeded
Tests / cures
UCCassist-2 can be used for further help with this by displaying the system status, the status bytes and signals.
Theamplifierandmotorcontactorfeedbacksignalscanalsobeexaminedusingthe‘inputsignals'windowinUCCassist2.
NOTE: A scale error will cause the UCC T5 to enter an error state which is not recoverable within a metrology application
environment. If a scale error occurs it will be necessary to reinitialise the installation due to the possibility of lost scale counts
and metrology being affected.
