Probable cause and remedy
Fault name and meaning
%h
Radiation fin overheated
(OH)
The temperature of the
radiation fins of the Inverter
has reached 110
_
C
±
10
_
C.
•
The ambient temperature is too high.
→
Ventilate the Inverter or install a cooling unit.
•
The load is excessive.
→
Reduce the load.
→
Change the inverter to one with a higher capacity.
•
The V/f setting is incorrect.
→
Reduce the V/f set voltage.
•
The acceleration/deceleration time is too short.
→
Increase the acceleration/deceleration time.
•
The ventilation is obstructed.
→
Change the location of the Inverter to meet the
installation conditions.
•
The cooling fan of the Inverter does not work.
→
Replace the cooling fan.
%l1
Motor overload (OL1)
The electric thermal relay
actuated the motor overload
protective function.
Calculate the heat radiation of
the motor from the output
current of the Inverter based
on the rated motor current
(n036), motor protection
characteristics (n037), and
motor protective time setting
(n038).
•
The load is excessive.
→
Reduce the load.
→
Increase the motor capacity.
•
The V/f setting is incorrect.
→
Reduce the V/f set voltage.
•
The value in n013 for maximum voltage frequency is low.
→
Check the motor nameplate and set n013 to the rated
frequency.
•
The acceleration/deceleration time is too short.
→
Increase the acceleration/deceleration time.
•
The value in n036 for rated motor current is incorrect.
→
Check the motor nameplate and set n036 to the rated
current.
•
The Inverter is driving more than one motor.
→
Disable the motor overload protective function and install
an electronic thermal relay for each of the motors.
The motor overload protective function is disabled by
setting n036 to 0.0 or n037 to 2.
•
The motor protective time setting in n038 is short.
→
Set n038 to 8 (the default value).
%l2
Inverter overload (OL2)
The electronic thermal relay
has actuated the Inverter
overload protective function.
•
The load is excessive.
→
Reduce the load.
•
The V/f setting is incorrect.
→
Reduce the V/f set voltage.
•
The acceleration/deceleration time is too short.
→
Increase the acceleration/deceleration time.
•
The Inverter capacity is insufficient.
→
Use an Inverter model with a higher capacity.
