Setpoint response according to example 2
Example 3:
Two-setpoint mode with a synchronization controller without local / remote
switchover:
1.
One variable setpoint
w1 = c2
∗
wE + c1
2.
The setpoint w2 = c1 defined by parameterization and not affected by
the front controls
Both setpoints are thus linked by the fixed component c1; the switch-over
from w1 to w2 takes place simply by external switching off of w2. A setpoint
ramp Tw > 0 is provided.
