Fault Name Cause Possible Solution
FbL will be triggered
while the PID feedback
falls below the level
set to b5-12 for longer
than the time set to
b5-13. malfunction
4. Incorrect feedback input
circuit replace the board or the drive.
oH
Heatsink Overheat
Heatsink temperature
over 90 to 100°C
(Overheat level is
determined by rating of
the drive)
1. Ambient temperature is
too high
2. Internal cooling fan
stopped operating
3. Bad air flow due to
insufficient room.
1.Check the temperature
surrounding the drive
a. Improve the air flow inside the
enclosure panel
b. Install an air conditioner or fan to
cool the environment
c. Remove any possible source of
heat
2. Measure the output current
a. Reduce the load
b. Lower setting in C6-00 ( Carrier
Frequency Option )
3.Replace the cooling fan
oH1
Motor Overheat
The temperature signal
from motor temperature
sensor via the terminal
MT exceeded the
overheat detection level
of the drive.
1. Incorrect motor
temperature input (terminal
MT) wiring
2. Fault on the machinery
(e.g., machinery is locked
up)
3. Motor overheat
1. Correct the wiring for terminal
MT.
2. Check the machinery status
3. Check the load, acceleration /
deceleration time and cycle time
a. Reduce the load.
b. Increase the C1-00 to C1-07
(Acc./Dec. Time) settings
c. Adjust d1-02 to d1-11 (V/F
Characteristics)
ot1
Overtorque Detection 1
The current has exceeded
the torque level set to
P6-01 for longer than the
time set to P6-02
1. Incorrect parameter
settings
2. Malfunction on
machinery
1. Reset P6-01 and P6-02
2. Check machinery and load status
ot2
Overtorque Detection 2
The current has exceeded
the torque level set to
P6-04 for longer than the
time set to P6-05
1. Incorrect parameter
settings
2. Malfunction on
machinery
1. Reset P6-04 and P6-05
2. Check machinery and load status
