VSP analog input control mode and PGout configuration

VSP analog input control mode can be configured in the options page for MCEWizard by clicking and selecting

in the pull down list marked with red box as shown in Figure 26.

Figure 26 Analog VSP control input mode configuration

There are three input thresholds (percentage of controller supply voltage VDD) used to define the relationship

between VSP input voltage and TargetSpeed.

1. T1 (Input threshold for motor start): if the VSP analog voltage is above this threshold, motor will start

2. T2 (Input threshold for motor stop): if the VSP analog voltage is below this threshold, motor will stop

3. T3 (Input threshold for Max RPM): if the VSP analog voltage is higher or equal to this threshold, TargetSpeed

will be 16384 which is Max RPM.
