7-2-2 Malfunctions Followed by Alarms

(1) Overcurrent

1) Vector control and sensorless vector control

Over current IPM Error
OC IPE

YES

Is inverter output wiring (U, V, W)

short-circuited to ground?

(Disconnect output wiring and make

sure no continuity with ground)

Is inverter inside wiring

short-circuited to ground?

(Make sure no continuity

between U, V, or W terminal

of motor and ground)

Did overcurrent happen during motor

parameter tuning

(function code H01).

Is sensoless control

(code P01 or A01) selected?

Is PG pulse number specification

correct?

Are there any problems with wiring
from PG?
- Is shield line connected wrongly?
- Is signal line or power line
disconnected?
- Is signal line twisted with power line?

Is PG defective?

Use oscilloscope to check PG waveform.

Inverter fault is suspected.

Contact FUJI.

Did overcurrent alarm occur on rapid

acceleraion/deceleration?

Eliminate ground fault.

You must replace motor.

Contact FUJI.

Increase data for exciting current

(function code P08 or A10)

and execute motor parameter

tuning again.

Specify again according to motor PG.

Adjust wiring.

Replace motor PG.

Increase acceleration/deceleration times

(code F07, F08, C46, C47, C56, C57,

C66 or C67) longer and operate.

YES

Is the carrier frequency setting

between 2 and 15kHz?

Specify the carrier frequency setting

between 2 and 15kHz.
