then it can be switched on with a positive edge (i.e. the signal changes
from FALSE to TRUE) at ON/OFF1, of SINAMICS G.
Manual/automatic switchover (manual mode)
This function enables selecting whether SINAMICS G shall be controlled with the
values pending at the block inputs, or whether internal values shall be used and
the block inputs be ignored.
The internal values are located in the instance DB ("internal_Control_word" and
"internal_Status_word") and can be specified by a visualization.
This enables realizing a switch-over between the values supplied by SIMATIC S7
(automatic) and the specification via a visualization (manual).
Independent of these settings, the bits of the status word and the actual values are
always output.
When switching over (activating or deactivating the manual mode), the
control word and the setpoint value are not adjusted. It is therefore
possible when switching over that SINAMICS G automatically starts up or

changes the speed.
