System and functional description
Figure 19
Analog VSP control input mode configuration
Figure 20 explains that there are three input thresholds (percentage of controller supply voltage VDD) that are
used to define the relationship between the Vsp input voltage and the “TargetSpeed”.
1. T1 (Input threshold for motor start): if the Vsp analog voltage is above this threshold, the motor will start
2. T2 (Input threshold for motor stop): if the Vsp analog voltage is below this threshold, the motor will stop
3. T3 (Input threshold for Max RPM): if the Vsp analog voltage is higher or equal to this threshold, the
“TargetSpeed” will be 16384 which is the maximum speed (MaxRPM).

The relationship between VSP analog input voltage and TargetSpeed
After configuring the analog Vsp control input mode, the three input thresholds can be set up in the input text
box in MCEWizard marked with a red box as shown in Figure 21, or in the pages for Question of T1, Question of
T2 and Question of T3.
