Outputting reverse rotation detection signal
The direction of motor rotation is detected for every electrical angle of 360°. (The output is high
immediately after reset.)
The REV terminal increases to a 180° turn-on mode at the time of low.

Protecting input pin
1.
Over-current protection (Pin Idc)
When the DC-link-current exceeds the internal reference voltage, gate block protection is performed.
Over-current protection is released for each carrier frequency.
Reference voltage
= 0.5 V (typ.)
2.
Gate block protection (Pin RES)
When the input signal level is Low, the output is turned off; when the signal is High, the output is
restarted.
Abnormalities are detected externally, and the signal is input to the pin RES.

Internal protection
Positional signal abnormality protection
When the positional signal is HHH or LLL, the output is turned off; otherwise, the output is
restarted.
Low power supply voltage protection (VCC monitor)
Outside the operating voltage range, the turn-on signal output is kept at high impedance to
prevent damage caused by short-circuiting of power components when the power supply is turned
on or off.
