8. Troubleshooting
Description of trouble Possible cause Solution
1. Wiring error Refer to the wiring diagram
1.
Check the power input wiring
2. Is there a voltage for U.V.W output
2. Wrong settings at operator panel The function code No.04 is as follows
0: Panel key operation
1: External signals
3. Inverter displays fault indication Refer to “Protect Function”
4. Motor cannot start due to overload Exchange a higher capacity one
5. Motor breaks down Repair motor
The motor does not
run at all
6. Inverter breaks down Please contact us
1. Motor wiring error Refer to the wiring diagram
2. Terminals of inverter and motor
(U.V.W.) circuit shorted or ground
connection Banish circuit shorted or ground connection
3. Overload Reduce the load or increase inverter
capacity
4. Is V/F slope appropriate Check Code 05 V/F slope is appropriate
with motor specification
5. Is start torque appropriate Adjust Code 07 torque boost to over come
steady friction but not over current trip.
6. Is the acceleration time too short
when compared to load GD
2
Lengthen acceleration time by apply Code
08 and Code 10 or increase inverter
capacity
“OCPA” is indicated
as soon as the motor
is started.
(Overcurrent protects
operation during
acceleration.)
7. The inverter is starting during
motor free-run Refers to Code 28, change the value from 0
to 1
“OCPd” is indicated
as the motor is
decelerating. (Over
current protects
operation during
deceleration). 1. Deceleration time too short, unable
to be loaded Apply Code 09 and Code 11 to lengthen
deceleration time or increase inverter
capacity
1. Short circuit on U.V.W or
grounding for motor Exclude short circuit or grounding
2. Instantaneously mechanical load
on motor Reduce load or increase inverter capacity
3. Motor breaks down Repair motor
“OC” or “OCS” is
indicated during
operation. (Over
current)
4. Inverter breaks down Please contact us
1. Is power voltage with the
specification Improve power voltage condition
2. Braking resistor not applied Apply braking resistor, increase braking
ratio
“OU” is displayed
during inverter
operation
3. Deceleration time too short, unable
to be loaded Apply Code 09 and Code 11 to lengthen
deceleration time
1. Is power voltage with the
specification Improve power voltage condition
2. Instantaneous power voltage
failure Check the capacity of the power facilities
“PLU” is displayed
during inverter
operation
3. Power dropped and the protector
function has operated Check the capacity of the power facilities
1. Overload Reduce load or increase inverter capacity “OL” is displayed
during inverter
operation
2. Is inverter over current limiter
appropriate Apply Code 06 to re-set motor rated current
1. Check if the cooling fan is still
working Change cooling fan and clean dirt “OH” is displayed
during inverter
operation
2. Is ambient temperature too hot Improve ambient temperature condition
1. Power failure Check the capacity of the power facilities No any indication,
the output frequency
displayed “0”
2. Is there loosen part on external
control terminal Check external control terminal
