Introduction 11
NOTE:
This document has been updated to cover the introduction of the UCClite-2
controller. Unless otherwise stated all references to the UCClite-2 also apply to
the UCClite.
1. Introduction
The purpose of this chapter is to describe the UCClite-2 (universal CMM controller) and the available
options.
1.1 Overview
The UCClite-2 is an addition to the Renishaw CMM controller product range. Utilising the UCC1 platform
introduced in 1997, the UCClite-2 offers similar system performance and capability.
The complete range of Renishaw 2 wire kinematic touch-trigger probes is supported. Conventional
contact and strain-gauge sensors, manual and motorised probe heads with appropriate probe or stylus
changers, only with supporting hardware (i.e. PH10 head will need a PHC10-2 which will be connected to
the serial comms port on the UCClite-2).
The UCClite-2 comprise of a controller in a 19 inch rack-mountable enclosure with a processor based
computer system. It is coupled to the CMM host computer by a USB 1.1 link and to the CMM by external
cable interface connectors.
The UCClite-2 CMM controller has the capability of:
•Controlling three axes of a CMM (accepting digital readhead signals and generating three axes drive
motor control signals)
•Accepting input signals from emergency stop, air pressure, crash detector, contactor feedback,
amplifier faults and all axis inner and outer travel limit switches
•Accepting two uncommitted general purpose input signals and generating one uncommitted general
purpose output signal
•Serial communication for use with a Renishaw PHC10 controller
•Directly supporting the TP1, TP2, TP6, TP20 touch-trigger probes
•Indirectly supporting the TP200 via an external PI200 interface
•Directly supporting the Renishaw SPAlite, SPA2or SPA1 servo power amplifier
•Providing a +24 V supply for use by the CMM switches
•The UCClite-2 supports the MCUlite joystick, it can also support the MCU1 and MCU5.
•The UCClite supports USB DirectX joysticks.

12 Introduction
1.2 CMM host computer
For the installation of a UCClite-2 controller, the CMM host computer must use Windows 2000 or Windows
XP Pro as an operating system and a hard disc drive with available storage space of at least 300 Mbytes.
The processor speed and RAM requirements are not excessive, if the PC supports the operating system
and application software, it will almost certainly support the UCC controller operation. A minimum
specification of 1 GHz processor speed and 256 Mb RAM is recommended.
For UCClite-2 only one free USB port is required as the MCU joystick plugs directly into the controller.
For UCClite the PC must have two free USB ports available for the communication and the system
joystick. It is recommended NOT to use a USB hub because of the reduction in speed of operation these
devices normally produce.
1.3 Installation software
1.3.1 Renicis
The Renishaw Renicis program is a utility to assist the engineer to install, commission and maintain a
CMM system based on the UCClite and UCClite-2 controllers.
It also has features which assist in the development of a software interface between any existing CMM
application program and the UCClite or UCClite-2.
Please refer to the Renicis user’s guide (Renishaw part number H-1000-5058) for more information on this
product.
1.3.2 UCCassist
The UCCassist software suite complements the Renicis software package offering the following additional
capabilities of:
•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
•Error mapping for manual machines
1.3.3 Licence key manager
This is a stand-alone software utility, which is used to check and update the licence for controller
functionality.
1.3.4 Joystick set-up (UCClite only)
This is a stand-alone software utility, which is used to check and modify the joystick operation when using
the UCClite system.

Description of the UCClite and UCClite-2 15
2 Description of the UCClite-2
2.1 UCClite-2 features
The unit has the following facilities:
•Rear panel connectors for the external interface cables to and from the CMM
•Rear panel USB connection for the two-way communication link to the CMM host computer
•Rear panel connection for a Renishaw MCU joystick (UCClite-2 only)
•Readhead circuitry for CMM digital measuring scales
•Axis servo control circuits
•Status indicating LEDs
•Control electronics for probes and peripheral devices attached to the CMM
LEDs visible through the front panel of the UCClite-2 enclosure indicate the operational status of the
UCClite-2.
Sub-circuits in the unit control the following interfaces through connectors on the rear panel of the
enclosure:
•USB data link to the CMM host computer
•X, Y, Z axis data input from the CMM readheads
•A communication loop (SPA-A and SPA-B) to the SPAlite or SPA2servo power amplifiers
•Connections for the TP20, TP1, TP2 and TP6 touch-trigger probes
•Signal outputs to the axis drive motors servo amplifiers of the CMM
•I/O connections to limit switches, air pressure and other digital inputs and outputs
2.1.1 TTP interface
The UCClite-2 unit incorporates the circuitry and software necessary to interface with the Renishaw TP20,
TP1, TP2 and TP6 probes.
2.2 Power supply unit
When the UCClite-2 is not connected to a SPAlite digital servo power amplifier it requires an external
24 V DC 2.5 amp power supply.
2.3 Joystick
UCClite-2 has an input for a MCUlite (or MCU1 / MCU5) joystick and therefore does not require a joystick
to be connected to a USB port on the system P.C
The UCClite does not have an input for a joystick control but the system will require one. The system has
been designed for use with a USB joystick connected directly to a USB port on the system P.C.

16 Description of the UCClite and UCClite-2
NOTE: Care should be taken to ensure that for UCClite systems the joystick is always plugged into the
same USB port that it was connected to when the joystick drivers were installed. If it is unplugged and
subsequently plugged into a different USB port then the drivers may have to be reinstalled.
CAUTION: If a wireless joystick is used they normally go to sleep when not in use to preserve
battery life. If the speed control is changed while the joystick is in sleep mode then unexpected
movement could occur when the joystick is woken up.
The UCC software installation includes two utility programmes for use with UCClite only:
1. A ‘joystick configurer’ utility, which allows the joystick directions and function switches to be
configured. The use of this utility is covered in chapter 11 of this manual.
2. A ‘joystick display’ window. This is a status window, similar to the screen on the MCU1 joystick,
that pops up on the P.C. screen. The use of this utility is covered in chapter 10 of this manual.
NOTE: UCClite-2 requires neither the ‘joystick configurer’ nor the ‘joystick display’ window utilities.

Installation of the UCClite and UCClite-2 components 17
3 Installation of the UCClite-2 components
The purpose of this chapter is to describe the procedure for installing the CMM controller and connections.
3.1 General wiring standards
To achieve reliable operation of the UCClite-2 and the CMM host computer, the following should be
observed:
•Scale readhead signals, reference marks and error signals should comply with EIA RS-422A. It is
recommended that each readhead has its own screened cable and that these cables are kept well
away from electrically noisy wiring such as motor supplies, etc.
•All opto-isolated inputs and outputs should be separate from other connections to the UCClite-2
controller, so that the CMM electrical system is kept isolated from the circuitry within the controller,
with the exception of the 0 V reference and protective grounding.
•All signal cables MUST be screened and all cable screens should be connected electrically to the
cable connector’s metal shells. Cable screens should only be connected to the protective earth (via
the connector shell) at the UCClite-2 and SPA end, and not directly connected to the CMM
protective earth. This is to avoid earth loops. However, the protective grounding must be continuous
between the controller and all other equipment in the installation. All cable connectors should be
secured to the UCClite-2 by the connector jack screws.
•See also the installation instructions supplied with other Renishaw components in the system,
i.e. probes or probe heads etc. Particular attention should be paid to the screening and earthing
methods of the cables carrying signals from probes.
NOTE: The UCClite-2 electronics 0 V rail is connected to the overall ground plane at a star point within
the UCClite-2.
3.1.1 Preparations
Before beginning the installation of the UCClite-2 check the following items:
•Ensure that all connecting cables, test equipment and software are available.
•Ensure that the CMM measuring scales/readheads are correctly installed and are functioning.
•Ensure that all the CMM status and limit switches etc. are correctly installed and have been function
checked.
•Ensure that all power has been removed from the CMM, the CMM host computer, CMM servo power
amplifiers and CMM axis drive motors etc.

18 Installation of the UCClite and UCClite-2 components
3.2 Connecting UCClite-2 cables to and from CMM
•Attach all CMM cable connectors to the mating sockets on the UCClite-2.
•Secure all cable connectors with the connector jack screws to ensure physical and electrical
connection.
•Secure all cables for strain relief without reducing access for servicing.
3.3 Connecting the UCClite-2 power supply
WARNING: There is no internal fuse on the power supply to the UCClite-2. The installer must
provide suitable protection.
The maximum current demand of the UCClite-2 is 2.5 A at 24 V.
3.3.1 Connection to the SPAlite power supply
3. Remove all power from the installation.
4. Connect the servo power amplifier interconnection cable between the SPAlite and the UCClite-2
(A-5121-0062). The SPAlite will power the UCClite-2 through the SPA connector cable, this supply
is protected.
3.3.2 Connection to an external power supply
5. Remove all power from the installation.
6. Connect the UCClite-2 power supply P-EA02-0021 to the power input connector on the rear of the
UCClite-2 respectively.
