Manualcontrolsystemsdescription
NOTE: Unless otherwise specified, all information supplied in this guide applies to the MCU1,
MCUlite-2 and the MCU5.
MCU1
The manual control unit (MCU1) is a comprehensive CMM joystick controller designed for use with
Renishaw’s universal CMM controller range. Including the functionality of both the Renishaw
standard UCC joystick interface and Renishaw PHC10 hand control unit (HCU1), the MCU1 connects
to the UCC controllers as shown.
MCUlite‐2
The MCUlite-2 is a basic low cost joystick . It has the controls necessary to control a 3-axis touch-
trigger CMM but without the sophistication of a LCD display screen.
MCU5
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 dynamic measuring head and probe
system, where the STOP switch is provided to augment the ESTOP switch. The ESTOP switch has
to cut the motor power to all the axes, including the two REVO axes. This is not always appropriate
as the REVO 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 MCUlite-2 is not compatible with UCC1.

Systemoperation
In normal operation the application software will put the CMM in manual mode, joystick enabled,
except when an automatic DCC program is running.
LCD(NotapplicableforMCUlite‐2)
This LCD screen is context sensitive to the mode and operation of the MCU. Please refer to the
relevant operational mode section for further details.
Emergencystop
The motors are disengaged when the emergency stop switch is operated, any motorised head motion
will also be stopped.
Speedoverride
Controls the machine speed when the CMM is running a program under DCC mode. It will also
control the speed of the REVO head if fitted. The LCD screen displays a percentage value of the
programmed move speed when in DCC operation as shown below. If the speed override is set to less
than 10%, the speed percentage shown on the LCD display will flash.
For MCUlite-2 the indication for the speed override being set below 10% is a flashing ‘MCU enabled’
LED.
ProbedisabledLED
Indicates the status of the touch probe signal.
LED off - Normal operational mode.
LED lit (red) - Probe disabled.
MCUenabledLED
Indicates the operational status of the MCU. For the MCU1 and MCU5 this LED has two states.
LED off - MCU not enabled.
LED lit (green) - MCU enabled.
NOTE: The LED is not illuminated until the joystick is live, so if the setting of the ‘Joystick

For the MCUlite-2 this LED has 5 states as described below:
LED off - System not switched on or MCUlite-2 not connected
LED lit (red) - System in automatic mode (joystick not enabled)
LED lit (amber) - System in manual mode but joystick not enabled
LED lit (green) - Joystick enabled
LED lit (red flashing) - Speed override set below 10% in automatic mode.
If both the ‘MCU enabled’ LED and ‘Probe disabled’ LED are flashing (‘MCU enabled’ LED flashing
between red and green, ‘Probe disabled’ LED flashing red on/off) this indicates there is a scale failure
on one of the CMM axes.
enable’ function is that this button has to be operated the LED will not illuminate until this is
done.
Joystickenablebutton
On the MCU1 and MCU5 the ‘Joystick enable’ is a single button. On MCUlite-2 there are 4 buttons,
to enable ‘Slow’ speed on each side (left and right handed use) and to enable ‘Fast’ speed on each
side as well.
The ‘Joystick enable’ button is intended to be used as a ‘deadman’s handle’, preventing the
accidental movement of the machine. If enabled, two actions are required to initiate CMM motion:
press ‘Joystick enable’ button and operate the joystick.
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.
For the MCU1 and MCU5, 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
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 a LED indicator that will light red when the respective axis is
locked, on the MCU1 and MCU5 there will also be a padlock symbol next to the respective axis, see

figure below. These buttons toggle on or off.
When the MCUlite-2, MCU1 or MCU5 are in head mode, the axis locks are applied to the comparable
head axes.
On the MCU5 only, when the joystick is in head mode and a REVO head is fitted, the left / right axis
lock button is used to initialise / 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 be re-latched when returning to manual operation.
NOTE: If an axis lock is released when the joystick is deflected, that axis is immediately free to
move.
NOTE: On the MCU1 and MCU5 the axis locks will be transposed when operation of the
CMM joystick orientation function of the joystick is operated.
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.
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 MCU1 and MCU5 a symbol at the top of the LCD screen (next to the direction arrow)
also indicates whether the servos are engaged.
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.
