Fault Output Signal
a1 : Control supply voltage rises: After the voltage rises UVCCR, the circuits start to operate when next input is applied.
a2 : Normal operation: IGBT ON and carrying current.
a3 : Under voltage detection (UVCCD).
a4 : IGBT OFF in spite of control input condition.
a5 : Fault output operation starts.
a6 : Under voltage reset (UVCCR).
a7 : Normal operation: IGBT ON and carrying current.

Fault Output Signal
b1 : Control supply voltage rises: After the voltage reaches UVBSR, the circuits start to operate when next input is applied.
b2 : Normal operation: IGBT ON and carrying current.
b3 : Under voltage detection (UVBSD).
b4 : IGBT OFF in spite of control input condition, but there is no fault output signal.
b5 : Under voltage reset (UVBSR)
b6 : Normal operation: IGBT ON and carrying current
