Inverter Overcurrent protection and Motor Gatekill configuration

Figure 24 displays the overcurrent protection circuitry. The current sensing signal I_Shunt is connected to ITRIP

via the resistor R32, and ITRIP is filtered through capacitor C21.

trigger low which is mean that the signal Gatekill is active. For iMOTION™ IMC1xx control IC, there are three

types of Gatekill Input Source (as shown in Figure 25). For Gatekill Input Source configured Gatekill-Pin or Both,

iMOTION™ control IC will stop the Motor when the signal GateKill is active.

But please note that, if select comparator for Gatekill Input Source, the external Gatekill signal will be not used.

And the current sensing signal I_Shunt will be compared by the internal comparator with the “Gatekill

Comparator Reference” value set in MCEWizard only.
