Abnormalities are detected externally, and the signal is input to the pin RES.
When the DC-link-current exceeds the internal reference voltage, gate block protection is performed.
Reference voltage = 0.5 V (typ.)
When the input signal level is Low, the output is turned off; when the signal is High, the output is
