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

types of Gatekill input sources (as shown in Figure 17). For the input source configured as “Gatekill-pin” or

“

Both”, the iMOTION™ control IC will stop the motor when the GateKill signal is active.

But please note that if the comparator for the Gatekill input source is selected, the external Gatekill signal will

not be used. And the current-sensing signal I_Shunt will be compared by the internal comparator with the

“Gatekill Comparator Reference” value only set in MCEWizard.
