Manual control systems description
MCUlite-2
The MCUlite-2 is a basic entry level joystick . It has the controls necessary to control a 3-axis touch-trigger CMM but without the sophistication
of an LCD display screen.
NOTE: The MCUlite-2 is not compatible with UCC1.
The MCU1 and HCU are not supported on the same installation.
MCU5
The manual control unit is a comprehensive CMM joystick controller designed for use with Renishaw's universal CMM controller range. It
includes the functionality of both the Renishaw standard UCC joystick interface and Renishaw PHC10 hand control unit (HCU1).
The MCU5 is a derivative of the MCU1 joystick, the only difference being the addition of a STOP switch on the membrane keypad.
The MCU5 has been developed for use with Renishaw's REVO system and PH20, where the STOP switch is provided to augment the E-STOP
switch. The E-STOP switch has to cut the motor power to all the axes, including the two head axes. This is not always appropriate as the head
A‐axis will drop to 0° by gravity. Operation of the STOP switch will bring the CMM to a fast stop but the motors will remain engaged in the
‘hold' state.
NOTE: The MCU5 is not compatible with UCC1.
THE MCU5 and HCU are not supported on the same installation.
MCU W
The wireless manual control unit (MCU W) is a comprehensive joystick designed for use with Renishaw's range of UCC controllers. Based on
the MCU5 joystick design, the MCU W uses modern battery technology and Bluetooth® radio modules to provide an effective wireless
joystick with a maximum of twenty five metre range and over eight hours between battery changes. A spare battery and an automatic charger
are included in the joystick docking cradle.
NOTE: The MCU-W is not compatible with UCC1.
The MCU-W and HCU are not supported on the same installation.
Configuration
All MCU units can be configured to match the customer's requirements using Renishaw UCCassist software. Contact Renishaw CMM support
for details.

System operation
Joystick enable button - MCU5 and MCU W
On the MCU there is a single joystick enable button. The joystick enable button is intended to be used to prevent the accidental movement of
the machine. Two actions are required to initiate CMM motion: press joystick enable button and operate the joystick.
NOTE: On the MCUlite-2 the enable buttons are the green arrows in the green boxes.
Joystick and associated button function
All three axis movements are controlled from the one joystick. Moving the joystick left, right, backwards and forwards controls the CMM X and
Y movements. The Z-axis is controlled by twisting the joystick clockwise and anti-clockwise (configurable) *.
If a trigger event occurs during joystick operation, the CMM will stop and back away from the surface along the vector that it was travelling.
After the back off operation, it is necessary for the joystick to return to its null position for a set period of time before the joystick will permit
movement of the CMM. The default value is 0.05 seconds *. The back-off speeds and distances are defined by the UCC configuration settings
*.
When in head mode, operation of the joystick can move the axis of the head. Pushing the joystick forwards and backwards will operate the A-
axis and twisting the joystick will operate the B-axis.
When in rotary table mode, the W-axis of the table is controlled by the twisting of the joystick.
* These values and configuration settings will have been set by your CMM service provider.
Joystick axis locks buttons
These permit the locking of one or more axes of the CMM, ignoring any joystick deflections for that axis. On each of the axis lock buttons there
is an LED indicator that will light red when the respective axis is locked, on the MCU there will also be a padlock symbol next to the respective
axis, see figure below. These buttons toggle on or off.
NOTE: If an axis lock is released when the joystick is deflected, that axis is immediately free to move.
MCUlite-2, MCU5 and MCU W installation and user's guide
www.renishaw.com
Issued 07 2019
16
NOTE: On the MCU the axis locks will be transposed when operation of the CMM joystick orientation function of the joystick is
operated.
When the MCU is in head mode, the axis locks are applied to the comparable head axes. On the MCU, when the joystick is in head mode and a
REVO head is fitted, the left / right axis lock button is used to initialise and cancel ‘SNAP ON'. ‘SNAP ON' is the ability to move the head to the
nearest multiple of a defined head angle. These axis locks will only be active during manual (MCU) controlled CMM movements. When the
CMM is under DCC operation, all axis locks will be released and re-latched when returning to manual operation.
Probe disable button
The probe disable button gives the CMM user the ability to move the CMM while the probe is triggered or disconnected by disabling the
probe trigger signal.
WARNING: When operating in this mode the probe is disabled and therefore probe contact with a surface will NOT stop the CMM.
No measured data will be returned to the CMM host computer.
The probe disable function will only work while in manual mode and cannot be applied while in DCC. Press and hold the joystick enable
button and then press the probe disable button. The CMM can now be moved irrespective of the probe trigger status. Releasing the joystick
enable button cancels the probe disable function. In all modes the application of probe disable is confirmed by the red probe disabled LED
being illuminated.
Engage button
The engage button gives the CMM user the ability to engage or disengage the servos whilst the CMM is in manual mode. This button is
configured as a toggle switch and has an associated LED to indicate the servo status. The LED (located within the button) identifies the various
operational states and these are as listed below. On the MCU5 and MCU W, a symbol at the top of the LCD screen (shown below) also
indicates whether the servos are engaged.

CMM servos are disengaged
LED off – The CMM servos are disengaged
CMM servos engaging
LED amber – The servos are in the process of engaging
CMM servos engaged
LED red – The servos are engaged but the joystick is not enabled
CMM servos engaged and movement is demanded
LED green – The servos are engaged and the joystick is enabled and ready
When REVO or PH20 are fitted, operating the engage switch to disengage the drives puts the REVO or PH20 into heavily damped mode
where it will slowly droop due to gravity. The CMM axes will disengage as normal.
Program button - MCU5 and MCU W
This button can be used to request the application software to start or stop a DCC program by a system integrator. The button only gives an
event to the application software and is not a state button.
NOTE: It is the system integrator's responsibility to ensure adequate precautions are taken if this switch is utilised. If it is
considered dangerous for the operator to be in the machine working volume when the DCC program is started, then a second
confirmation switch operation is required (possibly one of the function switches) or this switch should not be enabled at all.
If the button is used to start a program ﴾enter auto mode﴿, the LCD screen will display ‘AUTO', the speed, the controller status and an optional
text line from the OEM whilst the program is running. If the button is used to stop a program (enter manual mode) the MCU5 / MCU W
returns to the previous mode selected before going into DCC. The LCD screen will then display the normal features for that mode.

Issued 07 2019
18
Modes button- MCU5 and MCU W
There are six possible MCU5 / MCU W operational modes in addition to the DCC auto mode. Pressing the ‘MODE' button on the MCU keypad
changes the MCU operational mode, the current mode is indicated in the top left of the LCD.
NOTE: The modes available to the user of the MCU are configurable. If the mode is not required it can be switched off.
CMM manual mode
This mode is the default on start-up. In manual mode the LCD display will show the tip position of the stylus in the current part co-ordinate
system, in either metric or imperial measurements.
Head mode
Head mode provides the user with control over the Renishaw PH10, PH20 or REVO heads. In this mode the joystick will move either of the
motorised head axes. The LCD display will indicate the angle of the two head-rotation axes. For the PH10, the joystick fast / slow button will
give jog operation if not pressed or fast sweep operation if pressed. For the REVO, the fast / slow button will control the speed. If no head is
fitted then the LCD screen will display ‘None'.
NOTE: To ensure correct operation, the head type must be set correctly within the configuration.ini file.
MCUlite-2, MCU5 and MCU W installation and user's guide
www.renishaw.com
Issued 07 2019
19
With the REVO or PH20 head there is an additional facility of ‘SNAP ON'. The use of ‘SNAP ON' is controlled by the use of the left / right axis
lock button. Repeated pressing will toggle the facility on and off. ‘SNAP ON' is displayed in text on the LCD display when it is selected. When
‘SNAP ON' is selected the up / down and twist operation of the joystick will move the REVO or PH20 ‘A' and ‘B' axes normally, but after about
1 second of the joystick being returned to its null position the head will automatically move to the nearest multiple of the snap angle. The
snap angle is configurable via the configuration file. The maximum snap angle is 7.5° and the minimum is 0.05°.
Rotary table mode
This mode provides the user with control over a rotary table if it is connected to the system. Twisting the joystick will cause rotary table
movement. The joystick fast / slow button will control fast (pressed) or slow (not pressed) operation. The LCD display will indicate its angle of
rotation.
Sticky button mode
The purpose of sticky button mode is to allow the user to alternate between two MCU modes without having to scroll through all of the
enabled MCU modes. This feature could be useful when generating a part program using the application software teach utility, where
alternating between CMM and head moves is often required.
If the use of sticky button mode has been enabled by your CMM service provider, you will notice that when a MCU mode is selected, the title
(e.g. CMM Manual, Head Mode, etc), will be highlighted by displaying it in reverse video (see following example). The highlighted mode title
will persist for the time set in the sticky button time delay parameter.
If you want to toggle between two specific modes, this can set by using the following procedure;
a) Using the MCU mode switch, select one of the desired modes, then wait until the mode title returns to a normal video display.
b) Next select the other desired mode and again wait for its mode title to return to normal video.
c) The sticky buttons are now set.
