Interface mode
The interface mode is used for adjusting the assignment of the control and status
words to suit other SIEMENS drive systems when PROFIBUS is used.
When you set a telegram in the range between 100 and 199, interface mode is set
by default (p2038 = 1) and cannot be changed.
The mode can be set as follows:
Value Interface mode
S p2038 = 0 SINAMICS (factory setting)
S p2038 = 1 SIMODRIVE 611 universal
Procedure:
1. Set p0922 999
2. Set p2038 = set required interface mode
