3 Installation and commissioning
3.1 User manual
The module can be used as a multiturn or singleturn absolute encoder. It can be configured to
the profiles CLASS 1 (Huebner 1.0), with parameterization of the count direction, or CLASS 2
(Huebner 2.0), with the additional setting of the resolution in units/turn and the total measuring
range.
The profiles Huebner 2.1 and Huebner 2.2 are also available. These enable the following
additional functions:
- Expanded scaling function
- Setting of code sequence (count direction), preset and automatic scaling (teach-in)
during online operation in commissioning mode.
- Limit switch function
- Velocity/speed output
These functions shift a portion of the computing effort from the Profibus® master to the
absolute encoder, thus reducing the load on the system as a whole. However, if these extra
functions are not needed, then it makes sense to keep the parameterization simple, by using a
CLASS 1 or CLASS 2 profile.

UOC40_EPF-Config-manual-en_R1
3.2 Profibus for the absolute encoder
The module behaves like a multiturn encoder that has been designed to operate with Profibus®.
It can be configured and parameterized to the following profiles, as a multiturn or singleturn
encoder:

3.3 Joining the encoder to the Profibus
After the encoder has been installed and the electrical connections have been made, it is joined
to the Profibussystem. The following is an example, using the COM PROFIBUS V 5.0 installation
software with an IM308C Profibus-DP master.
First of all, the manufacturer-specific bitmap files (*.bmp, *.dib) are copied to the bitmaps direc-
tory, and the GSD file is copied to the GSD directory of the COM PROFIBUS software. Next,
start the COM PROFIBUS installation software. In the FILE menu, create a new configuration
file in the menu item NEW, or use the menu item OPEN to call up an existing configuration file.
The GSD file is now read in, using the menu item READ GSD FILES.
In the selection list, under DP Master, select the type IM308C, and under DP Slave / Encoder,
select the HUEBNER encoder AMP1212, and place them in the bus graphic in the right window
with a double click.
By selecting the menu item CONFIGURE / DP SLAVE CONFIGURE, or by clicking with the
mouse pointer on the encoder icon, you can access the Slave properties window. The bus
address of the encoder must be entered here, to match the setting of the address selector
switches in the terminal box of the encoder.
Then continue with the Configure menu.

3.4 Configuring the encoder
Now select the profile for the encoder operation. The input and output address are then
assigned, and the parameterization can be carried out. This function can be called up by the
PARAMETERS button in the CONFIGURE window, and provides a clear and simple way of
setting the parameters.
Parameterization through other windows has to be performed in hexadecimal format, an
operation which demands precise knowledge of the significance of the individual bits and
bytes.
3.5 Parameterizing the encoder
In this example, the PARAMETERIZE window shows the options for setting the parameters for
an absolute encoder that has been configured for HUEBNER 2.0.
Note:
If Class 2 functionality is switched off, then the encoder operates in the HUEBNER 1.0 mode.
The only option available is to change the count direction (code sequence). The resolution in
units per revolution can have any value from 1 to 4096, and this determines the size of the unit.
The total measuring range defines the measurement path length as the number of revolutions
with the given resolution (units per revolution) until the zero position is reached again.

U-ONE®-Compact UOC40
Configuration-manual PROFIBUS-DP - module
UOC40_EPF-Config-manual-en_R1
13
NOTE!
Total measuring range = units per revolution x number of revolutions
The number of revolutions must have a value 2n, where n can be from 0 to 12
If this is not taken into account, the encoder will detect a parameter error. This is indicated on
the cover of the terminal box. The red LED lights continuously, while the green one blinks.
NOTE!
To activate the parameterization of Measuring units per revolution, Class 2
functionality and the scaling function must be switched on. The preset value
then has to be reset in the normal operating mode, since it is referred to the
scaled value.
3.6 Parameterization in hex code
It is also possible to carry out the parameterization in the Hex parameter assignment window.
However, this is an awkward operation, requiring precise knowledge of the functions of the
individual bits and bytes.

3.7 Operating the encoder in the Huebner 2.1 and Huebner 2.2 profiles
Compared with the standard profiles, these two profiles offer several additional functions which
can be parameterized through COM Profibus®, as is explained below.
The SCALING FUNCTION must be activated as a precondition for using these additional
functions.

3.8 Desired measuring units per …
Compared with the HUEBNER 2.0 (CLASS 2) profile, three different scaling options are availa-
ble.
Required resolution: units per:
-revolution
-max. total measuring range
-physical pulse
3.8.1 Desired measuring units per revolution
Here you can define the number of units that the encoder produces per revolution. In addition,
the total possible path length for measurement, and thus the number of revolutions, is defined
in the fields for the total measuring range.
Example:
The required value is 8 units per revolution. The total measuring range should cover 8
revolutions, or repeat after 8 revolutions. This requires
8 x 8 = 64
units. So 8 units must be entered for DESIRED MEASURING UNITS, and 64 units for TOTAL
MEASURING RANGE.
CAUTION!
The number of revolutions must have a value of 2n.
If this is not observed ambiguous position values will occur, since the transition
from the maximum encoder position to the 0 position value will happen at various
encoder positions.
3.8.2 Desired measuring units per maximum total measuring range
For this type of scaling, the maximum possible measuring range of the encoder is divided into a
definite number of units. This number is then entered in the fields for DESIRED MEASURING
UNITS per.
Example:
The entire measuring range of the encoder is to be divided into 16384 units.
16384 / 4096 = 4 units per revolution
The number of units that are required must be smaller than the number for the total measuring
range.
This type of scaling is also used in commissioning mode, for automatic scaling (teach-in).

U-ONE®-Compact UOC40
Configuration-manual PROFIBUS-DP - module
16
UOC40_EPF-Config-manual-en_R1
3.8.3 Desired measuring units per physical pulse
This setting is always referred to the division of the code disk into 4096 pulse intervals. The
number that is entered in the entry fields for MEASURING UNITS is the number of parts into
which the value entered for PHYSICAL PULSES is to be divided.
Example:
Physical measurement pulses = 2048, required number of measuring units = 64
2048 / 64 =32
So the required measurement unit has a length of 32 physical intervals.
CAUTION!
This value must divide into the total measuring range 2ntimes. If this is not
observed, ambiguous position values will occur, since the transition from the
maximum encoder position to the zero position (0) will happen at various
encoder positions.
3.9 Commissioning mode
If this mode is activated, then the following functions are available in online operation:
changing the count direction (code sequence)
setting the preset value
automatic scaling (teach-in)
These values are set from the Profibus master, by manipulating the status bit in the
DDLM_DATA_EXCHANGE mode. A detailed description is included in a later section.
3.10 Limit switches
Two software limit switches are available, which can be activated through the fields UPPER
LIMIT SWITCH and LOWER LIMIT SWITCH. The required positions for the limit switches are
referred to the total measuring range that has been selected. They must not lie outside this
range, and are entered in the fields UPPER LIMIT SWITCH (HIGH/LOW) and LOWER LIMIT
SWITCH (HIGH/LOW).
As long as the encoder is positioned between the two switch positions, the corresponding
status bit (bit 27) is set to LOW. If the position goes outside the limits, i.e. above the upper
position or below the lower position, the bit is set to HIGH.
3.11 Velocity/speed output
This function can only be used with the HUEBNER 2.2 encoder profile. The following options
are available for the output:
units per 1000 milliseconds
units per 100 milliseconds
units per 10 milliseconds
revolutions per minute

4 Data transfer modes for Profibus
Three data transfer modes are needed for operating the encoder on a Profibus®:
When the system is started up, the data that are required for configuration and
parameterization are transferred in the DDLM_SET_PRM mode from the master to the
encoder (attached as a slave). 16 to 39 bytes (octets) are necessary for this operation,
depending on the encoder profile.
In the DDLM_Data_Exchange mode, the master requests data from the encoder
outputs. If the encoder is configured for Huebner 2.1 or Hübner 2.2, then some
parameters can be altered in online operation.
In the DDLM_Slave_Diag mode, the master requests diagnostic data from the encoder.
Normally, the configuration and parameterization in the DDLM_Set_Prm mode when the
system is started up, and the subsequent operation in the DDLM_DATA_EXCHANGE mode
are performed automatically.
The settings for the necessary functions are defined beforehand in the selection menus in the
windows of the Profibus system ( COMProfibus).
However, in some cases it is necessary to know the relevant commands, so that parameters
can also be altered manually.
4.1 Configuring and parameterizing the encoder
The following shows which bits can be set in the DDLM_SET_PRM mode. Octets 1-8 contain
Profibus-specific data, and should not be altered.
4.1.1 DDLM_Set_Prm - Mode for Class 1 and Class 2
In Class 1 operation, only the count direction (code sequence) bit can be altered.

4.1.1.1 Class 2 functionality (Octet 9.1)
This bit can be set to 0, to switch over to Class1 operation.
4.1.1.2 Scaling function control (octet 9.3)
If this bit is cleared, the encoder has a resolution of 4096 units per revolution, and a total meas-
uring range of 4096 x 4096 units (corresponding to 4096 revolutions). If bit 3 = 1, then it is
possible to make a scaling of the units per revolution and the total measuring range.
4.1.1.3 Resolution: units per revolution (octet 10 –13)
This value must not be larger than 4096, otherwise the output code will be ambiguous.
4.1.1.4 Total measuring range (octet 14 –17)
The value that is set here must be an exact multiple of the resolution (in units per revolution),
whereby the multiplying factor is the number of revolutions, and can only have a value 2n
(where 1 < n < 12).
CAUTION!
Total measuring range = units per revolution x number of revolutions
and number of revolutions = 2n
If any other value is used for the number of revolutions, then jumps will occur at the transition
from the maximum encoder position to position 0 , resulting in ambiguous position data.
4.1.2 DDLM_SET_PRM mode for HUEBNER 2.1 and HUEBNER 2.2
The user profiles HUEBNER 2.1 and HUEBNER 2.2 are an extensions of the CLASS 2 profile.
They provide additional functions that can be applied by the user. Unused functions can be
switched off. This makes it possible to use online parameterization in the
DDLM_DATA_EXCHANGE mode to set the code sequence (count direction), the preset value,
and to determine the gearing factor. Furthermore, HUEBNER 2.2 allows the output of a
velocity/speed value.
