4.10.2 Overview of “Simplified start with profile 2”
Figure 31:
Sequence for simplified start
In normal operation, a start is executed with bit 3 EN_OP.
In the event of a fault, the variable frequency drive/variable speed starter will
be set back two steps. Once the fault is eliminated, it needs to be reset
(Fault Ack). The step sequence must then be repeated starting from there.
Setpoints via input bytes 2 and 3 are displayed as integer values.

.
The direction of rotation is specified with a negative setpoint:
Example: -100 %

Actual values are returned in the same format via output bytes 2 and 3.
