Fault description
Possible causes
Solutions
Fu.014
Overheating of
frequency inverter
(sensor 1)
1. The air duct is blocked.
2. The ambient temperature is over high.
3. The fan is abnormal.
4. The temperature detecting circuit or power
module is abnormal.
1. Clean the air duct or improve
ventilation conditions.
2. Improve ventilation conditions and
reduce carrier frequency
3. Replace the fan.
4. Seek for the manufacturer’s
support.
Fu.015
Overheating of
frequency inverter
(sensor 2)
Same with above.
Same with above.
Fu.016
Overheating of
frequency inverter
(sensor 3)
Same with above.
Same with above.
Fu.017
External equipment
is faulty or the
panel has forced
stoppage
The external equipment of the frequency
inverter is faulty, the input terminal has signal
input.
Inspect signal source and relevant
equipment and find the root leading
to the stoppage of the panel.
Fu.018
Excessive
protection of
rotating speed
deviation
1. The load is too large.
2. The acceleration time is too short.
3. The load is locked.
4. The detection value ([F8.2.34]) and time
([F8.2.35]) for DEV is set improperly.
1. Reduce load.
2. Prolong acceleration and
deceleration time.
3. Confirm the mechanical system of
the load.
4. Reset the detection value
([F8.2.34]) and time ([F8.2.35]) for
DEV.
Fu.019
Over speed failure
(OS)
1. Overshoot or undershoot is occurred.
2. The frequency is too high.
3. The detection value ([F8.2.36]) and time
([F8.2.37]) for over speed is set
improperly.
1. Adjust the gain.
2. Adjust the set value of frequency.
3. Reset the set value of the
detection value ([F8.2.36]) and
time ([F8.2.37]) of OS.
Fu.020
Reverse
connection of A, B
pulse
Mistaken connection of A, B pulse of PG
card.
1. Change the connection order of A,
B pulse, or,
2. Modify the setting of parameter
F8.0.06, or,
3. Exchange any two wires from U,
V, W
Fu.021
The master
contactor is not
actuated well. Or
the thruster of
major loop is not
conducted.
1. The DC side master contactor in the
frequency inverter is not actuated well.
2. The power supply voltage is unstable with
frequent sudden change.
1. Clean the dust on the contact of
the master contactor.
2. Replace the master contactor
3. Close this protective function
(FF.1.21)
Fu.022
Internal data
memory is faulty
1. There is intense noise around in the
process of writing in function code data.
2. The internal memory is damaged.
1. Retry after reset.
2. Seek for manufacturer’s service.
