the UCC1 or UCC2 controllers enclosure or handling individual boards.

CAUTION: Removing the top panel of the UCC enclosure will give access to the mains

!

driver power supply (PSU). The PSU is further protected by a metal cover. This
protective cover MUST NOT BE REMOVED as it would expose hazardous voltages.

The following procedure is recommended for installing a daughtercard:

1. Remove the ac power supply from the UCC1 or UCC2 and move the unit so you have clear
access to the top and rear of the enclosure, it may be necessary to disconnect some of the
other cables to achieve this.

2. Remove the top panel of the UCC1 or UCC2 enclosure by removing the screws at the top
of the rear panel and the screw located at the top of each side panel, near the front. Retain
the fixing screws.

3. Select a socket on the motherboard to house the daughtercard (all sockets are compatible).

NOTE: Install long daughtercards and daughtercards with appreciable heat dissipation towards
the power supply end of the UCC1 or UCC2.

If the PHS daughtercard is to be installed into the UCC2 it must be fitted into the fourth socket
from the power supply.

4. Remove (and store for possible re-use) the appropriate blanking plate from the rear panel of
the enclosure.

5. Carefully position the daughtercard so that the rear connectors pass through the hole in the
controller rear panel, but without engaging the motherboard connector.

6. Align the daughtercard plug with the socket on the motherboard.

7. Check that the rear panel hook of the daughtercard is located above the slot in the rear
panel.

8. Press the daughtercard firmly into the socket on the motherboard until it is seen to be fully
engaged.

9. Confirm that the top hook is engaged in the rear panel, if it is not then repeat steps 7 and 8.

NOTE: This daughtercard is suitable for use in both UCC1 and UCC2 controllers.

3.1 Introduction

The PHC1050 interface board is one of a range of plug-in daughtercards for Renishaw CMM
controllers. It provides a simple interface between the PH10 probe head and the metrology front­end software using no external hardware and with minimal cabling and connectors.

Provision is made for a probe head hand controller (HCU1), although this is not necessary if an
MCU1 joystick is fitted to the system.

The PHC1050 is an internal option which enables the UCC1 or UCC2 to offer all the functions of
the Renishaw PHC10-2 probe head controller.

The PHC1050 supports the basic and extended command set from the front-end software in their
original format, ensuring interchangeability and an easy upgrade path. The commands are
transmitted via the link from the host PC to the UCC controller. Probe signals are handled directly
by the UCC1 or UCC2.

PHC1050 daughtercard 11

3.2 Connector and pin outs

On the rear panel of the PHC1050 are two connectors:

• The connection to the PH10 head, via the 15-way D-type plug labelled HEAD

• The optional connection to the HCU1, via the 9-way D-type socket labelled HCU

3.3 Configuration options

3.3.1 Two wire probe configuration

The diagram below shows a typical wiring arrangement for a two-wire touch trigger probe system
incorporating a PH10 motorised probe head.

The PHC1050 daughtercard may be fitted into any of the available slots in the UCC.

• The cable from the probe head should be connected to the 15-way D-type plug marked 'HEAD'
on the PHC1050 rear panel. The probe signals within this cable are connected automatically to
the UCC motherboard for interfacing.

• The cable from the hand control unit (if fitted) should be connected to the 9-way D-type socket.

NOTE: Ensure that the configuration switches on the PHC1050 card are both set to ‘ON’ UP
position as shown in diagram below (factory default). This routes the probe signal through the card
to the internal interface.

PHC1050

PHC1050 daughtercard 13

3.3.2 Multiwire probe configuration

The diagram below shows a typical wiring arrangement for a system incorporating an analogue
scanning probe (SP600) and two-wire touch trigger probe incorporating a PH10 motorised probe
head.

The head cable links the probe head to the PH1050 daughtercard and the multiwire cable
connects directly to the analogue probe socket on the rear panel of the controller, to permit
interfacing of TP2/6/20, TP200 and SP600 probes (and SP25 on UCC2).

The PHC1050 daughtercard may be fitted into any of the available slots in the UCC.

• The cable from the probe head should be connected to the 15-way D-type plug marked 'HEAD'

on the PHC1050 rear panel. The probe signals within this cable are connected automatically to
the UCC motherboard for interfacing.

• The cable from the hand control unit (if fitted) should be connected to the 9-way D-type socket

marked 'HCU' on the PHC1050 rear panel.

NOTE: Ensure that the configuration switches on the PHC1050 Card are both set to ‘OFF’
DOWN position as shown in diagram below. This routes only the head signals through the
PHC1050 card.

Failure to configure the switches as detailed can result in illegal triggers when using the system.

PHC1050
card

14 PHC1050 daughtercard

3.4 Operating overview

The PHC1050 must be installed within the UCC and connected to the PH10 motorised probe head
before the controller is powered up.

When the UCC software is downloaded, it searches the internal bus for daughtercards and will
detect the presence of the PHC1050 daughtercard.

NOTE: If no PHC1050 card is found and a PICS/RS232 daughtercard is identified on the UCC
internal bus, all PHC commands will be routed to the PICS/RS232 daughtercard for use by an
external motorised head controller.

However, if no PHC1050 or PICS/RS232 daughtercards are found then the system will return an
error if any motorised probe head commands are sent to the UCC1 controller.

The metrology front-end software may then configure the PHC1050 using UCC command 340
(PHC1050 initialise), refer to following section and the UCC command set (Renishaw part number
H-1000-5222) for more information.

3.4.1 Communication with the PHC1050

The CMM metrology front-end program can communicate with the probe head in a similar manner
to that used in the RS232C link with an external PHC system.

• The application selects commands from either the basic command set or the RECS (Renishaw
extended command set).

• The command is sent to the controller using UCC command number 336 (Write to PHC10), to
transfer the data.

• The UCC will automatically direct the command to the PHC1050 daughtercard. (If this is not
fitted refer to note above)

• Any reply is read by using the UCC command number 337 (Read from PHC10), referring to the
status flags as described in the UCC command set document.

3.4.2 Configuring the PHC1050 board

The only hardware configuration on the PHC1050 board is that for probe type selection, please
refer to section 3.3 for details.

Other configuration options for the PHC1050 daughtercard are software configurable using UCC1
command 340 (PHC1050 initialise). Refer to the UCC command set (Renishaw part number
H-1000-5222) for further details.

Following receipt of command 340 (PHC1050 initialise) the UCC system will enable/disable the
applicable options.

PHC1050 daughtercard 15

NOTE: As part of this process the servo motors, if engaged, will be disengaged and the
PHC1050 will be reset to its default manual or automatic mode.

The default configuration mode of the PHC1050 depends on whether a hand control unit is fitted
(manual mode) or not fitted (automatic mode). This mode can be changed by the use of command
336 (Write to PHC10).

3.4.3 Power-up sequence

The PHC1050 (or PICS/RS232) daughtercard is powered from the internal UCC power supply,
provided that all components are connected before power-up, they will initialise correctly.

Plugging or unplugging a motorised probe head with the system live is described in the basic
command set programming manual (H-1000-5075). The same process should be used with a
PHC1050.

3.4.4 Probe head operation

For programming probe head operation, refer to the basic command set programming manual
(Renishaw part number H-1000-5075), the same flow charts and programming techniques apply.

Any references in the basic command set programming manual with regards to RS232
communications should be replaced by the UCC commands 336 (Write to PHC10) and 337 (Read
from PHC10) to send data over the link to the PHC1050 or PICS/RS232 daughtercard via the
UCC controller.

NOTE: None of the IEEE488 communications protocols are supported by the UCC system.

In this connection scheme it is necessary to configure the PHC10-2 as detailed in section 4.3.1, it
is also necessary to manufacture two RS232 cables as detailed in section 4.3.3 to connect the
ACC2-2 and the PHC10-2 to the PICS/RS232 daughtercard.

NOTE: If only an external ACC2-2 is to be used without the external interface and PHC10-2
controller then it is necessary to terminate the PICs signals used by the ACC2-2 controller. This is
done by placing a 100K resistor between pins 1 & 6 and 1 & 5 on the PIC IN connector of the
ACC2-2 unit.

5 Joystick interface daughtercard (JI card)

NOTE: This daughtercard is suitable for use in both UCC1 and UCC2 controllers.

5.1 Introduction

The joystick interface daughtercard (referred to in this document as the ‘JI card’) is one in a range
of plug-in daughtercards for the Renishaw UCC universal CMM controllers.

For the UCC1 kit (A-1333-0003) a JI card is provided as part of the kit. UCC1 kit (A-1333-0006)
provides an MCU1 (Renishaw joystick) interface.

The UCC2 controller has the MCU1 interface integrated into the motherboard and no other
interfaces are fitted. If a JI card is required then it must be ordered as a separate item
(A-1333-0020).

The JI card provides a flexible interface between the UCC controller and many different types of
OEM joystick control units. It has provision for analogue signals from the joystick unit. Multiple
switch and indicator signals can be accepted or provided.

The JI card is configured by commands from the metrology front-end software, via the UCC
controller, to select the required functions from the available range.

Physically, the device consists of a single printed circuit board with a connector to suit the
controller's internal bus sockets. The board has a metal end plate for fixing to the rear panel of a
UCC1 or UCC2 controller. Attached to the metal panel is a 37-way D-type plug, to connect to the
user's joystick unit, and a 2-way socket dedicated to the wiring from any emergency stop switch
on the joystick unit.

Electrically, the interface board carries an embedded processor and the required circuits to
process analogue joystick signals and to handle the two-way communications with the controller.

The JI board is powered by the UCC controller and will provide d.c. power to the joystick unit if
required.

5.2 Connector and pin outs

On the rear panel of the JI daughtercard are two connectors:

• the connection to the joystick unit, via a 37-way D-type connector, labelled joystick

• the connection to the CMMs emergency stop system, via a dedicated 2-way connector,

labelled EMERGENCY STOP

For recommended installation wiring please refer to the UCC1 or UCC2 installation guides
(Renishaw part numbers H-1000-5056 or H-1000-5223 respectively).

Joystick interface daughtercard 27

5.3.3 Analogue input signal

The figure below gives the analogue input circuit that is incorporated into the JI card. These are
all transient-protected and standardised.

There are connections for four analogue axis signals and one analogue speed signal from the
joystick unit to the UCC JI card.

The input voltage range is ±12 V nominal, ±15 V maximum. Positive inputs should produce
machine movements in a positive direction.

5.3.4 Binary input circuit

The figure below gives the binary input circuit that is incorporated into the JI card, which are all
transient-protected and standardised.

The input voltage range is ±12 V nominal, ±15 V maximum. The active state for this connection is
with the input connected to pin 2.

The active state for this connection is with the transistor conducting and the limits for this
connection are listed below.

Maximum output current = 100 mA

Output voltage @ 100 mA = 1.1 volts max.

5.4 Operating overview

5.4.1 Method of operation

The JI board CPU scans all inputs from the joystick unit, the analogue signals are processed to
give suitable velocity commands for the servo system and when information is requested by the
controller, these velocity commands and other input signals are returned to it.

The controller can also send instructions to the JI board to change the states of the outputs going
to the joystick unit, e.g. to turn indicators on or off.

There is provision for up to 19 user inputs or outputs from the joystick unit which can be
configured as simple I/O to and from the user’s PC, or as controls for many built-in functions.

Joystick interface daughtercard 29

5.4.2 Initialising the JI card

After powering up the UCC1 or UCC2 controller, the JI card must be brought into operation by the
following three actions:

• The JI card must be selected by setting Joystick type = 1 in the command 256 (Machine
configuration).

NOTE: This action will prevent the PC command 320 (Enter velocity demand) from working, since
the joystick will now provide this function.

• The JI card should also be configured to provide the characteristics required for the front-end
software application. Like most other parts of the UCC1 or UCC2 system, the JI board can be
used with all its parameters as their default settings, in which case no configuration is required.
Otherwise command 396 (Joystick configuration) should be sent to the controller. The board
can be configured before or after it has been selected.

• Finally, the JI card should be enabled using the command 397 (Joystick enable) command.

5.4.3 Joystick modes

When a CMM system is fitted with a joystick unit and a joystick daughtercard, these must be
suitably commissioned as described above. This will then permit the system to operate in one of
two modes: DCC mode or joystick mode.

In DCC mode the majority of the functions offered by the JI card are not active, moves can only be
initiated and controlled by commands from the front-end software.

NOTE: The emergency stop will always be available, if integrated, and the speed override
functions will be available if configured

In joystick mode the joystick(s) can be used to move the machine and all other JI card functions
are available, but no metrology front-end software controlled moves can be made.

The required mode can be selected either by a metrology front-end software command or by a
switch on the joystick unit.

30 Joystick interface daughtercard

NOTE: The default JI card characteristics can be changed using command 396.

This command may be used to remove the need for the dead man’s handle and joystick/DCC
switch signals. In this state the joystick must be enabled as required by command 397 and
disabled again by the same command when a computer controlled move is required.

5.4.4 Joystick type selection

Command 256 (Machine configuration) sets a parameter called joystick type to 0 or 1.

If joystick type is set to 0:

• No joystick functions will be available (even beeps or uncommitted I/O)

• Command 320 (Enter velocity demand) from the PC will operate to give mouse-like

movements controlled by the PC

If Joystick type is set to 1:

• JI functions may be available, depending on the other factors (see below)

• A command 320 (Enter velocity demand) from the PC will be ignored

5.4.5 Enable joystick

To move the machine under joystick control requires the following conditions to have been met:

• The JI must be selected using command 256 as type 1, see Joystick type selection section
below

• The JI must be enabled using command 397 with enable set to 1

• The dead man’s handle switch signal to the JI from the joystick unit must be active (contacts

closed)

• The joystick/DCC switch signal to the JI from the joystick unit must be active (contacts open or
pulled high)

Even when the JI is selected and enabled, the signal from the joystick/DCC switch on the JI
affects the joystick availability.

Joystick interface daughtercard 31

Since both the joystick/DCC switch and command 397 (Joystick enable) command from the PC
control the same things and both may be present, the truth table governing the system mode is:

Joystick/DCC switch set to

DCC

Joystick disabled by front

end software

Joystick enabled by front end

software

NOTE: If the joystick/DCC switch is not fitted to the JI card, the default state of the signal must be
wired to the joystick, on the JI connector, to allow the PC to control the mode.

Alternatively, the switch signal pin may be reconfigured (by command 396) for a secondary built-in
pin or as an uncommitted I/O pin: the PC command alone will then select the mode.

5.4.8 Changing modes

If a change occurs due to the Enable command or the joystick/DCC switch which would move the
system from DCC mode to joystick mode, it will not take effect until the system is in a disengaged
or hold state.

If a change occurs which would move the system from joystick mode to DCC mode, it will take
effect as soon as any joystick activity has been terminated by the user and the system is in a
disengaged or hold state.

5.4.9 Moving and touching

When joystick mode is selected, the CMM can be moved by deflecting the joystick levers. The
system behaviour can be modified by the optional primary I/O functions.

In the event of a trigger, the CMM will be stopped and back away from the surface. The back-off
speeds and distances are defined as the maximum values for normal moves and touches in
command 257 (Move configuration).

After backing-off and finally stopping, the joysticks cannot move the machine until all three joystick
signals have been at 0 speed for the null wait time defined in command 396 (Joystick
configuration). The default value is 0.05 seconds.

The back-off direction is the reverse of the direction in which the stylus approached the surface.

Joystick interface daughtercard 33

5.4.10 Recording points

It is often necessary to construct a program of moves and touches on the host for a repetitive
measuring procedure. Two of the primary built-in functions are designed to allow the user to log
chosen machine positions on the host as part of that construction.

When the user sends a Record point signal to the JI board, usually by pressing a momentary
switch on the joystick unit, the controller will store the current machine position and set a status
flag to alert the host. The flag is status byte B7, bit 1.

When next requesting position and status, the host should respond to this flag by recording the
position as a ‘way-point’ in the measuring program. Once the point has been read by the host, the
flag is set to zero.

If the user sends a Cancel last point signal to the JI board, usually by pressing a momentary
switch on the joystick unit, the controller will check that the last recorded point has been read by
the host. If it has not yet been read, the point data will be discarded and the Store as recorded
point flag cleared to zero. If the point has been read by the host, the controller will set a flag in
status byte B7, bit 2 to inform the host that the last recorded point it received should be cancelled.
The flag is cleared after it has been read by the host by the next request for position and status.

The cancelling process could be repeated many times and the host main program will use it to
delete multiple stored points.

5.4.11 Probe damping

Probe damping is not initialized by the joystick box, but if damping is asserted through the UCC,
and the system is in joystick mode, then probe damping will be controlled by the joystick fast/slow
switch:

If the joystick fast/slow switch is set for ‘slow’ speed then probe damping, if applied, is overridden
and the probe operates at full sensitivity.

If the joystick fast/slow switch is set for ‘fast’ speed then probe damping, if applied, is still valid and
the probe operates at reduced sensitivity.

If damping is asserted by an external device, such as an HCU1 unit or a connection to the
‘PDAMP’ line of the probe or PICS connector, then probe damping will not be overridden by the
fast/slow switch.

34 Joystick interface daughtercard

5.4.12 Joystick orientation

It is assumed that the joystick unit will normally be used in one position relative to the CMM’s table
(the home position) but during use, the joystick user will move freely around the table to control
the CMM.

By operating a switch mounted on the joystick unit, the X and Y joystick deflection signals can be
transposed as required to give instinctive user response for all four sides of the CMM table. The Z
axis is always in the same orientation.

NOTE: Any axis labelling on the joysticks themselves may no longer be correct.

This function is not controlled by command 396 (Joystick configuration), but is a hard-wired option
to the JI connector. The two signal pins which define the required orientation are pins 27 and 28.

NOTE: If both pins are left unconnected, the joystick unit will operate normally at the default
home position.

Joystick interface daughtercard 35

Should the operator switch the joystick unit orientation during use, then it will not change the
active orientation until the UCC is in state 0 (disengaged) or state 2 hold). Therefore the machine
should be left to reach one of these states (i.e. release joystick demand) to allow the change to
occur.

Axis locks are also affected by the joystick axis reorientation. If the user moves to position B or D,
the X and Y joystick axes will be interchanged on the joystick unit. Any existing or new axis locks
applied will also be interchanged when in either of these positions. Moving to a new position will
alter whichever axes are locked as required to maintain consistency with the joystick deflection
directions.

Joystick reorientation will only take effect if Joystick type is equal to analogue and the axis locks
and indicators are set as primary functions.

36 MCU1 daughtercard

6 MCU1 daughtercard

NOTE: This daughtercard is only suitable for use in the UCC1 controller. The UCC2 has this

functionality integrated as standard on its motherboard.

6.1 Introduction

The MCU1 daughtercard is one of two joystick interface options offered by the UCC1 and is
normally supplied as part of the UCC1 kit when purchased.

The MCU1 daughtercard provides all the necessary interfacing between the MCU1 joystick and
the UCC1 controller.

NOTE: The UCC2 controller has an integrated MCU interface that removes the requirement for a
separate MCU daughtercard to be fitted.

The MCU1 daughtercard is configured by commands from the front-end software, via the UCC1
controller, to select and respond to functions available from the MCU1 joystick.

Physically, the device comprises a single printed circuit board with a connector to suit the
controller’s internal bus sockets. The board has a metal end plate for fixing to the UCC1 controller.
Attached to this metal plate is a 9-way D-type connector, to connect to the MCU1 joystick, and a
2-way socket dedicated to the wiring from the emergency stop button located on the MCU1
joystick.

The MCU1 daughtercard and MCU1 joystick are powered by the UCC1 controller.

6.2 Connector and pin outs

On the rear panel of the MCU daughtercard are two connectors:

• the connection to the Renishaw MCU joystick unit, via a 9-way D-type connector, labelled MCU

10 Temperature sensor daughtercard

NOTE: This daughtercard is suitable for use in both UCC1 and UCC2 controllers.

10.1 Introduction

Up to 24 sensors can be monitored, with the information being used to compensate for
measurement errors introduced by thermal expansion. 23 permanently fixed sensors measure the
temperature of the desired parts of the CMM, and an additional sensor can monitor the
temperature of the part under inspection.

The daughtercard is designed for use with Beta Therm NTC 10K3A1 thermistors. These sensors
have an accuracy of up to +/- 0.1 º C (There are several manufacturers who make equivalent
devices). Other types of sensor can be used, however interface card hardware and software will
not be optimised for such devices.

10.2 Connector and pin outs

On the rear panel of the temperature sensor daughtercard there is a single connector:

• a 44-way D-type connector is used for connection of temperature sensors to the UCC system

10.3 Operating overview

The temperature sensor daughtercard has no user selectable settings.

Unused channels will be specified in the software that is downloaded to the UCC. Similarly,
whether the output from channels is to be used to make direct or differential temperature
measurements will also be specified in the downloaded software. This information affects the way
that the UCC1 processes the data from the interface card, but it is not required by the card itself.

48 Temperature sensor daughtercard

The temperature sensor daughtercard measures each input in rotation and digitises the result in a
12-bit word. Each measurement is then processed to reduce errors introduced by the electronic
circuit and interference signals before being stored in memory on the card. The resistance of each
sensor is then stored in a unique memory location, where it can be directly accessed by the UCC.

In addition to the sensor’s resistance, the interface provides the controller with the following status
information about each sensor and the card:

• The sensor’s resistance measurement is consistent and can be used by the UCC

• No sensor is connected/ the channel is open circuit

• The channel is faulty/ short circuit

• The temperature sensor interface card is OK

• The sensor is within the defined limits

10.3.1 Software integration

Software integration details are specified in the UCC command set document (Renishaw part
number H-1000-5222), please refer to this document for full integration details.

10.3.1.1 Configure the temperature sensor daughtercard

Command 436 (refer to UCC command set document, Renishaw part number H-1000-5222) is
used to configure the temperature sensor card.

10.3.1.2 Latch the temperature sensor daughtercard

Command 437 (refer to UCC command set document, Renishaw part number H-1000-5222) is

10.3.2.1 Thermistor connections to daughtercard

The 44-pin high-density D-type connector on the daughtercard has the following connections:

FUNCTION CONNECTION

Part under inspection sensor attached switch 1 pin

Part under inspection’s sensor signal 1 pin

CMM sensors’ signal (23 Channels) 23 pins

Sensors’ common connection (0 V) 19 pins *

Cable screen ground Via connector shell

NOTES:

* Common required for all sensors and part under inspection sensor attached switch common

Unused pins should be left open circuit inside the D type connector.

Each temperature sensor will have two terminals that are connected to the temperature sensor
daughtercard in the UCC.

It is recommended that to avoid having to re-wire the machine if a sensor has to be changed after
installation, the sensor should have connectors attached locally. These should plug into screened
cables that run through the CMM to where the UCC is located. At the UCC, all the cables from the
different temperature sensors should be bought together and wired into a 44-pin high-density
D-type socket connector.

50 Additional axis daughtercard

11 Additional axis daughtercard

NOTE: This daughtercard is suitable for use in both UCC1 and UCC2 controllers.

11.1 Introduction

The additional axis daughtercard is one of a range of plug-in daughtercards for the Renishaw
CMM controller products (UCC1 and UCC2).

This daughtercard has been created to enable the following capabilities to be added to the UCC1
system. It is also valid for the UCC2 controller but because the UCC2 is already a four axis
controller it is only needed when a fifth axis is required.

• Rotary table

• Additional axis (scale only)

• Additional axis (scale and drive)

The additional axis daughtercard offers the ability to change its internal reference address
permitting up to four of these cards to be fitted to a UCC.

11.2 Connector and pin outs

On the rear panel of the additional axis card are three connectors these are:

• The connection to the scale system, via a 15-way HDD connector, labelled scales.

• The connection to the rotary table or axis motor system, via a 15-way D-type connector,

labelled table/axis motor.

• The connection from the CMM’s emergency stop system, via a dedicated 1-way connector,
labelled E STOP. This connection is only required for a UCC1 system, it routes the CMM
emergency stop signal through to the table/axis motor connector and on to the servo power
amplifier. On UCC2 systems, the emergency stop signal is available on the motherboard
connector so the external connection is not required.

Additional axis daughtercard 51

11.2.1 Scale connector

The additional axis scale input connector is a high density 15-way D-type socket.

The socket is wired to the same pin-out as that of the UCC scale connector, suitable for Renishaw
RGH22 and RGH24 series head wiring. They will also accept the standard Renishaw digital output
scale reading heads or interpolators.

NOTE: Other manufacturers’ reading heads and interpolators may require an external adapter to
enable them to use the Renishaw standard reading head connector wiring. They may also not
produce an error signal to the RS-422 specification.

For further details refer to the scale input connector specification within the respective UCC
installation guide.

CAUTION: The connection of the cabling should be such that the CMM’s movements as

!

reported by the UCC system are of the correct polarity i.e. machine movement in a
positive direction along any axis should give positive change of position as reported to the
host computer by the UCC system. Adjust this, if required, by reversing the inputs of the
scale reading head signal.

Suggestion: label all read head connectors to avoid cross connection if removed and replaced in
the future.

Reference line for all signals.

11.2.2.5 Contactor feedback

This input signal (pin 5) is used by the UCC1 to monitor the operation of the axes drive motor
control contactor. When the contactor is energised this input pin should be pulled down to 0v line
to signal that motor power is available.

If the UCC1 has turned on the contactor output (pin 6) and the signal on this pin indicates that the
contactor has not operated after a short delay, the UCC1 will disable the drive motors and inform
the CMM host computer of this.

11.2.2.6 Contactor

The additional axis card provides a NFET output.

The transistor drain is available on pin 6 to be connected to the load and the source is connected
to the 0 V line (pin 4). This output is not optically isolated from the supply lines.

A collector pull-up resistor and a reverse spike protection diode connected between the drain (pin

6) and the source is provided within the IC.

Ratings: Maximum current 1 A.

Polarity: The output transistor conducts when the motors are intended to be energised.

11.2.2.10 Limit sw itches

The UCC1 will use these input signals (axis operation pins 1,9,11 and 14) to stop the CMM as
programmed by the host computer. Refer to UCC1 programmer’s guide (Renishaw part number
H-1000-5057), command number 311.

Both outer limit switches have to be closed before the CMM drives can be engaged.

When a CMM actuates an inner limit switch all CMM axes are decelerated, stopped and held
stationary under servo control. Refer to UCC programmers guide (Renishaw part number H-1000-

5057), command number 311 for further details).

If the CMM actuates either of the outer limit switches, all CMM axes servo drive motors are
disengaged.

12.3 Configuration options

The PHS daughtercard is constructed from two PCBs mounted together, these are the control
PCB and the power PCB.

The power PCB has the necessary circuits to permit the PHS to have a CAT2 emergency stop
system applied to it, if configured by the installer. All power supplied by the UCC2 to the PHS
system is controlled by this PCB. The card can be clearly identified by four large relays located on
the one side of the PCB.

The control PCB has the necessary circuits to control the movement of the PHS and interface to
the UCC2 control signals, it also has the external connectors mounted upon it.

12.3.1 PHS power PCB settings

The PHS power PCB has two configuration switches which are located on the upper edge of the
daughtercard between the power and control PCBs.

12.3.1.1 Configuration switch 1

This switch sets the PHS card emergency stop reset function.

When the switch is in the ON position (up) following an emergency stop, the card will
automatically reset itself into an operational state when the emergency stop has been removed.

When the switch is in the OFF position (down) following an emergency stop, the card will maintain
the emergency stop status when the emergency stop is removed from the system until a manual
reset has been applied.

12.3.1.2 Configuration switch 2

This switch sets the PHS card overtravel detection system.

When the switch is in the ON position (up) the PHS card will monitor the PHS head overtravel
mechanism and report on its status.

When the switch is in the OFF position (down) the PHS card will not monitor the PHS head
overtravel mechanism.

12.4 PHS card installation

The PHS card is generally installed into the UCC2 controller as specified in section 2.1 of this
handbook.

NOTE: The PHS card must be fitted into the fourth slot away from the power supply within the
controller

12.4.1 Power connection

The additional power supply required by the PHS to operate is supplied from a connector located
on the UCC2 motherboard.

PHS daughtercard 59

It is necessary to connect this supply to the PHS daughtercard using the loom supplied with the
kit.

The following procedure is recommended for installing the power supply loom to the PHS
daughtercard within the UCC2 controller.

1. The process of daughtercard installation as specified in section 2.1 must have been
completed to step 9.

2. Align the connector from one end of the power supply loom with the power connector pins
on the UCC2 motherboard and press firmly into position.

3. Align the connector from the other end of the power supply loom onto the power pins on the
daughtercard. Place a finger behind the connector on the daughtercard, then using another
finger, pinch the connector on the loom into place (see diagram below).

NOTE: The PHS daughtercard
must be fitted in slot 4.
