Explanation of the parameters
Parameters
• Expert characteristic curve: Free choice of reference between setpoint voltage and
speed. Clicking on P110 AI1 Scaling (Reference 3000 1/min), P113 AI1 voltage off-
set and P114 AI1 speed offset you can adapt the characteristic curve (
→
Figure 32).
The following structural diagram shows how a speed setpoint is created from an ex-
pert characteristic curve.
P113 AI1 Voltage
offset Unit: [V]
Setting range: –10 ... 0 ... 10 V
The zero passage of the setpoint characteristic curve can be moved along the U
E
axis.
