5. Correcting the lead angle
The lead angle can be corrected in the turn-on signal range from 0 to 58° in relation to the induced
voltage.
Analog input from LA pin (0 V to 5 V divided by 32):
0 V
=
0°
5 V
=
58° (when more than 5 V is input, 58°)
6. Setting the carrier frequency
This function sets the triangular wave cycle (carrier cycle) necessary for generating the PWM signal.
(The triangular wave is used for forcibly turning on the lower transistor when the motor is driven by
square wave.)
Carrier cycle
=
f
osc
/252 (Hz) f
osc
=
reference clock (crystal oscillation)
7. Switching the output of the turn-on signal
This function switches the output of the turn-on signal between HIGH and LOW.
Pin OS:
HIGH
=
active HIGH
LOW
=
active LOW
8. Outputting the reverse rotation detection signal
This function detects the motor rotation direction every electrical angle of 360°. (The output is HIGH
immediately after reset.)
The REV terminal increases with a 180° turn-on mode during LOW.
CW/CCW Pin

CCW (reverse)

9. Protecting input pin
1.
Overcurrent protection (Pin I
dc
)
When the DC-link-current exceeds the internal reference voltage, performs gate block protection.
Overcurrent protection is released for each carrier frequency.
Reference voltage
=
0.5 V (typ.)
Gate protection (Pin RES)
Output is turned off when the input signal is LOW, restarted when the input signal is HIGH.
The abnormality is detected externally and the signal input to pin RES.
2.
RES Pin
OS Pin
Output Turn-on Signal
(U, V, W, X, Y, Z)

LOW
(When RES
=
LOW, bootstrap capacitor charging stops.)
