Programmable Parameters
9.5.56 Object 6008h: High Resolution Position Value
This object contains a high-resolution position value up to 16 bit for single-turn and 31 bit for
multi-turn measurement. See nameplate to get the information about the maximum resolution
of your device.
Mutliturn encoder with resolution 32 bits is available upon request at Pepperl+Fuchs GmbH but
there are the following functional restrictions: Preset function and scaling function are not
possible.
9.5.57 Object 6030h: Speed Value
This object contains the speed value of the encoder.
If the velocity exceeds the data type, the speed value is frozen to the maximal possible value.
The customer can use the 3010h (32 bit) object.

Note!
The object 6008h is not influenced by the object 2102h total resolution or object 6002h Total
measuring range, because of their limited data type of unsigned 32 bit.
But object 2101h resolution per revolution and object 6001h measuring units per revolution will
affect the high-resolution position value. With object 2103h / 6003h Preset value a desired
position can be also set for the high-resolution position value, but only within the value range of
unsigned 32 bit. With this method the user has a downward compatible device, but also in
parallel a device with higher capability of resolution and the existing software in the PLC can be
kept.

Tip
SDO: 0x600 + node number. The following values are all in hex and the node number is "1"
DLC (Data length) = 8, 22 means "write", This example is written in intel-format (LSB ... MSB).
Depending on your tool, it could be, that the Motorola-format (MSB ... LSB) is used and the
direction of the bytes has to be changed.
