Safety
NOTE: For ambient temperatures under 40 °C the maximum output power for the SPA3 is 800 W. For temperatures between 40 °C
and 50 °C the maximum power is 400 W.
WARNING: SPA3 is not recommended for use in ambient temperatures above 50 °C.
WARNING: Earthing provisions for the complete machine is the responsibility of the OEM or installer.
WARNING: SPA3 is isolated from the power supply by disconnection of the ac power connector from the external PSU. If any
additional means of isolation is required, it must be specified and fitted by the machine manufacturer or the installer of the product.
The isolator must be sited within easy reach of the CMM operator and comply with IEC61010 and any applicable national wiring
regulations for the country of installation.
WARNING: The PSU must be single fault tolerant, approved to EN60950-1 and must be connected to a supply incorporating a
protective earth conductor. Earthing provisions and residual fault protection for the complete machine is the responsibility of the
OEM or installer.
Machine safety
WARNING: Switching off or isolating the SPA3 may NOT prevent unexpected machine movement. The user is advised to isolate
the machine from the electricity supply, compressed air or other energy sources in accordance with the machine manufacturer's
instructions before entering the danger zone or performing any maintenance operations.
If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.
The emergency stop safety system that has been integrated into the SPA3 is designed to achieve category 2 to standard BS EN ISO13849-
1:2008. This can be hardware configured to obtain category B. The risk assessment made by the system installer on the installation should
therefore have determined which category is required.
CAUTION: It is strongly recommended that the CMM manufacturer or retrofitter includes a periodic test of the emergency stop
and if fitted, the associated reset switch in their maintenance instructions.
The SPA3 must only be commissioned through Renishaw software. Failure to do so may result in unexpected machine movement.

SPA3 system overview
SPA3 is a servo power amplifier with enhancements for higher power and category 2 E-STOP.
SPA3 can be used with UCC2, UCC2-2, UCC T3-2, UCC T3 PLUS, UCC S3, UCC T5 and UCC S5 and have different connection requirements.
The high power capability combined with a compact form enables use of the SPA3 across a wide range of machines.
The SPA3 CMM amplifier has the capability of:
Powering three axes of a CMM
Accepting input signals from air pressure, crash detection and all axis inner and outer travel limit switches (not connected when used with
UCC2 / UCC2-2)
Accepting two uncommitted general purpose input signals and generating one uncommitted general purpose output signal (not connected
when used with UCC2 / UCC2-2)
Directly supporting the TP1, TP2, TP6 and TP20 touch-trigger probes (not connected when used with UCC2 / UCC2-2)
Providing a +24 V supply for use by the CMM switches (not connected when used with UCC2 / UCC2-2)
The SPA3 supports the MCUlite-2 joystick, it can also support the MCU5, MCU5-2, MCU W and MCU W-2 (not connected when used with
UCC2 / UCC2-2)
Providing power output of up to 800 W continuous and 960 W for up to 1 second
Setting the voltage of each axis is independent allowing differing motor voltages to be used without damage
Supporting dc motors in the range 12 V to 80 V and currents up to 10 A
Supporting encoder / tacho or linear encoders (torque mode) for velocity feedback
Simulating linear power amplifier - drive outputs are free from switching edges eliminating noise from drive PWM, improving repeatability
and reducing emissions
Providing category 2 E-STOP

SPA3 installation software
The SPA3 is supported in UCCsuite version 4.4.6 software or later. The software can be obtained online at www.renishaw.com/cmmsupport or
from your local Renishaw supplier. Follow the prompts to install the UCCserver software.
CAUTION: Do not power down the SPA3 when the parameters or firmware is being updated. This can cause an error that requires
the unit to be returned to Renishaw.
UCCassist-2
The Renishaw UCCassist-2 program is a utility to assist the engineer to install, commission and maintain a UCC controlled CMM.
Capabilities of the software include:
Basic machine system diagnostics
Operation with Renishaw's machine checking gauge, enabling the user to complete frequent volumetric accuracy tests to ensure the CMM
is running within the specified operational tolerances
Automated CMM error mapping routines, when used in conjunction with the Renishaw ML10 or XL80 laser systems

General wiring standards for the installation of
the SPA3
To achieve reliable operation of the SPA3 plus UCC, the following should be observed:
The PSU must be single fault tolerant, approved to EN60950-1 and must be connected to a supply incorporating a protective earth
conductor (earthing provisions and residual fault protection for the complete machine are the responsibility of the OEM or installer)
The system must be PAT tested before the equipment is powered
All signal cables MUST be screened and all cable screens should be connected electrically to the cable connector's metal shells
It is recommended that screens for motor cables should be connected to the shell on the SPA3 end and connected to the motor housing at
the CMM end
Signal cables such as tacho and scale cables should be connected to the SPA3 and have a cable shield that runs to the machine but is left
unconnected at the machine end
Please refer to appropriate product installation guides when installing other Renishaw components
Supply and motor cables that are used to connect the SPA3 to the CMM (that are not data cables) must have a minimum cross section of
0.3 mm
2
(as specified in EN 60204-1 para.12.6.)
SPA3 has a maximum voltage of 80 Vdc and peak current is 10 A (the actual peak current will be dependent on the size of the motor fitted
and how hard it needs to be driven, so cable sizes need to be calculated by the system installer)
All cable connectors should be secured to the SPA3 by the connector jack screws.
The power input to the SPA3 is via a 3W3 connector; refer to the Connector and signals section for more information.
SPA3 power requirements
The SPA3 amplifier requires 30 W of power to operate. This must be factored into the power supply used.

Installation
Mounting the SPA3
The SPA3 unit draws air from the right hand side when viewed from the front and expels air out of the left hand side. A minimum clearance
gap of 10 mm is necessary between the sides of the unit and any potential obstruction. The dimensions shown on the above drawing are in
mm (in).
Fitting mounting brackets (optional)
NOTE: The screws supplied with this kit are M5 × 6 mm countersink type.

The E-STOP connector is provided to allow connection of an external EMERGENCY STOP switch into the SPA3. The machine manufacturer or
product installer must perform a risk assessment to determine the requirements for emergency stopping and emergency switching off. The
SPA3 emergency stop safety system is designed to achieve category 2 or category B implementation as selected by the installer's risk
assessment (refer to BS EN ISO13849-1:2008 para. 5.2.2.).
The connection on the SPA3 is a 9WD plug connector with the following connections:

E-STOP electrical characteristics
Any emergency stop components fitted to this connector must have the following electrical characteristics:
Emergency stop system voltage : 24 V
Emergency stop system current : 300 mA max
All connections to this connector should be fitted by a competent technician or engineer and all wires should be sleeved. Any emergency stop
devices added to the E‐STOP chain should meet the requirements of IEC 60947‐5‐1 ﴾Low‐voltage switchgear and control gear – Part 5‐1:
Control circuit devices and switching elements – Electromechanical control circuit devices﴿ or UL1054 ﴾Standard for special‐use switches﴿.
NOTE: If there are no additional emergency stop devices to be added to the system, connect pin 1 to pin 4, and pin 6 to pin 7 to
permit the SPA3 emergency stop switch to function.
NOTE: If the RESET signal is not used connect pin 5 (RESET "A") to pin 9 (RESET "B").
If indicated by the user's risk assessment, a ‘manual reset' button ﴾refer to BS EN ISO13849‐1:2008 para. 5.2.2.﴿ should be included in the
emergency stop system. A reset switch is required when there is limited visibility of the danger zone from the control position. The reset
switch must be positioned outside the danger zone and in a safe position from which it may be determined that no person is within the
danger zone before resetting the safety system.
CAUTION: It is strongly recommended that the CMM manufacturer or retrofitter includes a periodic test of the emergency stop
and, if fitted, the associated reset switch in their maintenance instructions.
