You can interconnect any process data objects of the receive and transmit buffer using
receive and transmit double words.
● Scaling for percentage values:
– 16-bit (word): 4000 hex ≙ 100%
– 32-bit (doubleword) 4000000 hex ≙ 100%
● Scaling for values referred to units:
– 16 bit (word): 4000 hex ≙ value of the corresponding reference parameter for p200x
– 32-bit (double word) 4000000 hex ≙ Value of the corresponding reference parameter
for p200x
Example:
– For temperature values: 16-bit (word): 4000 hex ≙ p2006
– For temperature values: 32-bit (doubleword): 4000000 hex ≙ p2006
The "SINAMICS parameters" column shows the parameter numbers assigned in the inverter.
The assignment applies to the case in which an object which is not mapped in any PDO is to
be accessed via SDO.
