Fault Diagnosis and countermeasures

- 112-

U-11

Motor overload

Improper V/F curve

Adjust V/F curve and torque boost

power source voltage is too low

check power source voltage

General motor run at low speed with big

load

Can choose frequency conversion

motor for long time low speed run

motor overload protection factor set

incorrectly

to set motor overload protection

factor correctly

motor blocked up or load change too

suddenly and quickly

Reduce the load and check the

motor and

failure

code

failure type

possible reason

countermeasure

U-12

Missing input phase

Three-phase input power is abnormal

Check and remove the problems

in the peripheral lines,To make

the three-phase power entering

the frequency inverter normal

U-13

Missing output phase

The lead wire from inverter to the motor

is abnormal.

Remove peripheral fault.

Check if the three-phase output of
frequency inverter is balanced when
running without motor

Check if the motor three-phase
winding is normal, If no, remove
the fault.

U-14

inverter over heating

Air-path blocked

To clear air-path or improve

ventilation condition

Ambient temperature is too high

Improve ventilation condition,
lower carrier frequency

Fan damaged

Replace the fan

U-15

external device

failure

use sudden stop key in

non-keypad

run mode

Reset running

Use sudden stop key

under

condition of stall

Set running parameter correctly

Sudden stop terminal MI for external

failure closed

Open external failure terminal

after external failure is settled

U-16

RS485

communication

failure

Baud rate set improperly

set Baud rate properly
