Note
Using the HW Config configuration tool, a PROFIBUS slave / PROFINET device with two
interfaces cannot be shown. In parallel operation, this is the reason that SINAMICS drive
appears twice in the project or in two projects, although physically it is just one device.
Parameter
p8839
Description:
Values:
For p8839, the following rules apply:
● The setting of p8839 applies for all drive objects of a Control Unit (device parameter).
● For the setting p8839[0] = 99 and p8839[1] = 99 (automatic assignment, factory setting),
● An alarm is issued if the same hardware (Control Unit onboard or COMM BOARD) is
● If the CAN board (CBC10) is used, the entry of p8839[0] = 2 is not permissible (no
● If p8839[x] is set to 2, and the COMM BOARD is missing or defective, then the
