Code Name Causes Possible Solutions
oH1 Heatsink Overheat
The ambient temperature is high and the heatsink
temperature of the drive is more than the
oH1
detection level.
• Measure the ambient temperature.
• Increase the airflow in the control panel.
• Install a cooling device (cooling fan or air conditioner) to lower
the ambient temperature.
• Remove objects near the drive that are producing too much heat.
The load is too heavy.
•
Measure the output current.
•
Decrease the load.
•
Decrease the value set in C6-02 [Carrier Frequency Selection] .
Note:
•
The drive detects this fault if the heatsink temperature of the drive is more than the oH1 detection level. o2-04 [Drive Model (KVA) Selection] determines the oH1 detection level.
• Do a Fault Reset to clear the fault.
• L5-08 [Fault Reset Enable Select Grp2] disables the Auto Restart function.
Code Name Causes Possible Solutions
oH3 Motor Overheat (PTC Input)
The thermistor wiring that detects motor temperature
is defective. Correct wiring errors.
A fault occurred on the machine.
Example: The machine is locked.
Examine the machine and remove the cause of the fault
The motor has overheated.
•
Check the load level, acceleration/deceleration time, and motor
start/stop frequency (cycle time).
• Decrease the load.
• Increase the values set in C1-01 to C1-04 [Acceleration/
Deceleration Times] .
•
Set E2-01 [Motor Rated Current (FLA)] correctly to the value
specified by the motor nameplate.
• Make sure that the motor cooling system is operating correctly,
and repair or replace it if it is damaged.
• Adjust E1-04 to E1-10 [V/f Pattern Parameters] . Decrease the
values set in E1-08 [Mid Point A Voltage] and E1-10 [Minimum
Output Voltage] .
Note:
If the values set in E1-08 and E1-10 are too low, the overload
tolerance will decrease at low speeds.
Note:
•
When H3-02 or H3-10 = E [MFAI Function Selection = Motor Temperature (PTC Input)] , the drive detects this fault if the motor overheat signal entered to analog input terminals
A1 or A2 is more than the alarm detection level.
• Do a Fault Reset to clear the fault.
• If the drive detects this fault, it will operate the motor as specified by the Stopping Method set in L1-03 [Motor Thermistor oH Alarm Select] .

oH4 Motor Overheat Fault (PTC Input)
The motor has overheated. • Check the load level, acceleration/deceleration time, and motor
start/stop frequency (cycle time).
•
Decrease the load.
•
Increase the values set in C1-01 to C1-04 [Acceleration/
Deceleration Times] .
• Set E2-01 [Motor Rated Current (FLA)] correctly to the value
specified by the motor nameplate.
•
Make sure that the motor cooling system is operating correctly,
and repair or replace it if it is damaged.
• Adjust E1-04 to E1-10 [V/f Pattern Parameters] . Decrease the
values set in E1-08 [Mid Point A Voltage] and E1-10 [Minimum
Output Voltage] .
Note:
If E1-08 and E1-10 are set too low, the overload tolerance will
decrease at low speeds.
Note:
•
The drive detects this fault if the motor overheat signal that was entered to an analog input terminals A1or A2 is more than the alarm detection level. (If H3-02 or H3-10= E [MFAI
Function Select = Motor Temperature (PTC Input)] was set.)
• Do a Fault Reset to clear the fault.
Code Name Causes Possible Solutions
oL1 Motor Overload
The load is too heavy. Decrease the load.
Note:
Reset oL1 when U4-16 [Motor oL1 Level] < 100.
The acceleration/deceleration times or cycle times are
too short. • Examine the acceleration/deceleration times and the motor start/
stop frequencies (cycle times).
•
Increase the values set in C1-01 to C1-04 [Acceleration/
Deceleration Times] .
