KE300A Inverter Trouble Shooting

174

8.2 Common Faults and Solutions

No.

Fault

Reason

Solution

1

No display
when power-on

The input voltage is 0 or too low.
The switching power supply on the
power board is broken.
Rectifier bridge is broken.
Buffer resistors are broken.
The control board or keypad is broken.

Check the input power-supply.
Reconnect the keypad and 40-core
flat cable.

2

E-23 is
displayed when
power-on

The motor or the output line is short
circuited to the ground.
The inverter is damaged.

Measure the insulation of the motor
and output line with
magneto-ohmmeter.

3

E-14 is
displayed
frequently

Carrier frequency is too high.
Fans are broken or air duct is broken.
The inverter inside components are
broken (such as thermistor)

Reduce the carrier frequency
(P0-15). Replace fans, clear the air
duct.

4

Motor does not
run after the
inverter runs

Motor and motor cables are abnormal.
  The inverter parameters are set
improperly (motor parameter).
The connection of the cables of the
power  board and control board are not
good.
The power board is broken

Make sure the connection of the
inverter and motor is very well.
Replace the motor or clear the
mechanical failure. Check & reset the
motor parameters.

5

Digital terminal
is invalid

The parameter is set improperly.
The external signal is wrong.
The jumper between PLC and +24V is
loose.
The control board is broken.

Check & reset P4 group parameters.
Reconnect the external signal cable.
Reconnect the jumper between PLC
and +24V.

6

Over voltage
and over current
fault are
displayed
frequently

Motor parameters are set improperly.
The ACC/DEC time is improper.
The load fluctuates.

Reset motor parameters or perform
auto tuning.
Set proper ACC/DEC time.

7

Power on display

Inverter initialization failure. The relative
components of the control board are
broken.

Check the keypad and 40-core flat
cable. Replace the control board.
