The X-coordinate defines a voltage value between 0 and 10 V for the analogue input:

)(][ 
The Y-coordinate defines the associated set value for this point. Depending on the control mode, this may be
a speed (closed-loop speed control), a sensor value (closed-loop sensor control) or a modulation level (open-
loop PWM control).

value Set
For voltages at the analogue input that are less than the value defined by the point 1 X-coordinate, the set
value is the value defined in the point 1 Y-coordinate.
For voltages at the analogue input that are greater than the value defined by the point 2 X-coordinate, the set
value is the value defined in the point 2 Y-coordinate.
In between, the set value changes linearly between the two values specified in the Y-coordinates
(see diagram above).
