2. Assembly
1. Drill a Ø 6x10 mm hole in the body of the machine with a 30 mm centre
distance from the shaft to fit the rear referring pin.
2. Fit the indicator onto the shaft and make sure that the referring pin fits into the
hole.
3. Clamp the bushing to the shaft by tightening the grub screw with hexagon
socket and cup end, according to UNI 5929-85.

6. Operating mode
6.1 System description
DD52R-E-RF, position indicators, with battery power supply, can be used on
passing through shafts in any position to provide the reading of the absolute or
incremental positioning of a machine component.
The system comprises the following components:
- Control unit UC-RF
- Max 36 electronic position indicators DD52-E-RF
The control unit UC-RF is provided with a standard interface (for the most common
industrial busses) to be connected to the PLC and allows the transmission of the
information between the PLC and the DD52R-E-RF position indicators. The UC-RF
exchanges information with the DD52R-E-RF via radio frequency and allows
the setting of the target position and the control of the current position of each
indicators, directly from the PLC.
6.2 Programming the network parameter (nEt id) and the channel parameter
(nEt ch)
The system radio network is defined by the following parameters:
- nEt id: id 00/99
- nEt ch: ch 01/36
These parameters can be configured on the radio menu of the indicator (see cap. 7) and
must be set according to the PLC recipe to guarantee a perfect communication
between UC-RF and DD52R-E-RF.
6.3 Targets
Target positions can be sent from the PLC to the indicators through the control unit.
When a target is set, one of the symbols reported below appears on the top right of the
display, to suggest the direction of rotation of the spindle to get to the target position:
Counter-clockwise rotation. The symbol flashes.
Clockwise rotation. The symbol flashes.
Counter-clockwise rotation. Target position almost reached. The arrow flashes.
Clockwise rotation. Target position almost reached. The arrow flashes.
Target position reached.

___0__
The menu function
__0___
allows the customer to choose between the options
d_tArG
or
d_to_GO
(factory detail).
Selecting
d_tArG
, when a new target position is set, the display will keep showing
the present position. If the present position differs from the target an indication will start
flashing. Turn the spindle according to the direction shown by the flashing arrows
or to get to the target position. Press the button
to see the target position
set.
Selecting
d_to_GO
, as soon as the indicator receives a new position from the
PLC, the display starts flashing, showing the distance between the actual and
the target position. To get to the target position, it is necessary to rotate the shaft
following the flashing arrows or until the number on the display becomes
zero. Once the target position is reached, the display will stop flashing showing
the actual position of the indicator. If the spindle is moved and get out of the
desired tolerance, the display will start flashing again. To visualise the actual
position while the display is flashing, keep pressed the button .
6.3.1 Target tolerance
Set the value of
P_toll
parameter to define the tollerance allowed for target (see
cap. 7.3 for detail).
6.4 Absolute / incremental measuring mode selection
Press the key to select the absolute or incremental measuring mode.
The measuring mode selected is shown on the display by the symbols:
-
ABS
: absolute measuring mode
-
REL
: incremental measuring mode
It is possible to change the key function by setting the
parameter
___0__
in the menu (see cap. 7.1).
The available options are:
-
ArCLr
(default): passing from
ABS
to
REL
the counter is set to zero.
-
Ar
: passing from
ABS
to
REL
the counter is not set to zero. In this case, the
counter is set to zero by pressing + .
-
OFF
: the key is disabled and does not allow changing the selected
measuring mode.
To program the parameters listed above, see paragraph 7.2.

6.5 Unit of measure selection
Press the key to select the unit of measure needed. The options available are
millimeters, inches and degrees.
The measuring mode selected is shown on the display by the symbols:
-
mm
: millimeters -
INCH
: inches -
D
: degrees
It is possible to change the key function by setting the
parameter
_____0
in the menu (see cap. 7.1).
The available options are:
-
ALL
(default): units of measure that can be selected: mm, inch, D
-
nodEG
: units of measure that can be selected: mm, inch
-
OFF
:
the key is disabled and does not allow changing the selected measuring mode.
To program the parameters listed above, see paragraph 7.2.
6.6 Setting the absolute reference
After having selected the absolute measuring mode and stopped the shaft in the
starting position or in the reference position, press the key combination
+the screen will display the last compensation value used (eg
OFFS 0
).
Choose the desired compensation value by pressing the key or , and
then press the key to confirm, this will set the absolute value to the sum of the
values of the parameters
OriGin
(absolute value of reference) and
OFFSET
(compensation value).
The value of compensation (offset) allows you to adjust the value shown on the
display in such a way that takes into account, for example the wear or tool change.
The system allows you to store up to 10 values of compensation.
To program the offset values, see parameter
OFFSET
of paragraph 7.2.
It is possible to change the function of the keys combination
by setting the parameter
0__0__
in the menu (see cap. 7.1).

The available options are:
-
L_OrG
: the reference value and the compensation value are set as shown
above. Choose the desired offset among the 10 available values, then press
the key to confirm;
-
OFF
: the keys combination + is not associated to any function in the
operating mode.
To program the parameters listed above, see paragraph 7.2.
6.7 Direct programming of the absolute reference value (source) - of the
compensation value (offset) - of the reading after one revolution
The function of the keys combination + allows direct access to the
programming of one of the following parameters, depending on the value assigned
to parameter
0____0
(see paragraph 7.1 for the instruction to set values).
It is possible to change the function of the keys combination
by setting the parameter
0____0
The available options are:
-
P_OrG
: direct programming of the absolute reference value (OrG parameter)
-
P_StP
: direct programming of the reading after one revolution (StEP parameter)
-
P_OFS
: direct programming of the compensation value (OFFS parameter)
-
OFF
: the keys combination +is not associated to any function in
the operating mode
For programming the parameters listed above see parameter
0____0
