Transmit PDO 8 mapping parameter
Number of mapped application objects in PDO
1 PDO mapping for the first application object to be
p8737.0 U32 0 r/w
2 PDO mapping for the second application object to
p8737.1 U32 0 r/w
3 PDO mapping for the third application object to be
p8737.2 U32 0 r/w
4 PDO mapping for the fourth application object to
p8737.3 U32 0 r/w
You can interconnect any process data objects of the receive and transmit buffer using
receive and transmit double words.
● Scaling the process data of the free objects:
– 16-bit (word): 4000 hex ≙ 100%
– 32-bit (doubleword) 4000000 hex ≙ 100%
– For temperature values: 16-bit (word): 4000 hex ≙ 100 °C
– For temperature values: 32-bit (doubleword): 4000000 hex ≙ 100 °C
The "SINAMICS parameters" column shows the parameter numbers assigned in the
converter. The assignment applies to the case in which an object which is not mapped in any
PDO is to be accessed via SDO.
