8) GND pin

・Two GND pins (9 & 16 pin) are connected inside IPM. Please connect one pin (16 pin is recommended.) to the 15V power

supply GND outside and leave the other open.

・If control GND is connected with power GND by common broad pattern, it may cause malfunction by power GND

fluctuation. It is recommended to connect control GND and power GND at only a point N (near the pin of shunt resistor).

・To prevent malfunction, the wiring of A should be as short as possible.

9) NU, NV, NW pin

・When operating with one-shunt resistor, please short the three pins(NU, NV, NW). In addition, to prevent malfunction, the

wiring of C should be as short as possible.

GND

NU

NV

NW

NU, NV, NW should be all connected each other at nearest pins.

N

Wiring inductance should be less than 10nH.

(Inductance of a copper pattern with length=17mm, width=3mm is about 10nH.)

Low inductance shunt resistor like surface mounted (SMD) type is recommended.

RC filter

Wiring from GND pin should be connected close

to the pin of shunt resistor.

Wiring from shunt resistor to RC filter should be connected

near the pin of shunt resistor.
