Fault Name
Cause
Possible Solution
Heatsink temperature
over 95°C
2. Internal cooling fan
stopped operating
3. Bad air flow due to
insufficient room.
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
multi-funtion analog
input (E3-01=20)
exceeded the overheat
detection level of the
drive.
1. Fault on the machinery
(e.g., machinery is locked
up)
2. Motor overheat
1. Check the machinery status
2. 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
ov
Overvoltage
Voltage in the DC bus
exceeded the
overvoltage detection
level
1.200 V class: 410 V
2.400 V class: 820 V( 740
V when d1-01＜400 )
1. Drive input power has
surge voltage entering
2. Machinery output short
circuit
3. Ground fault in the
output circuit causes the
DC bus capacitor to
overcharge
4. Electrical signal
interference causes drive
malfunction
1. Install a DC link choke
Voltage surge can result from a
thyristor convertor and phase
advancing capacitor using the
same input power supply
2. Check the motor power cable,
relay terminals and motor
terminal box
3. Correct grounding shorts and
reapply power
4. Check the solutions for
interference suppression
