Cause
Check if the ambient temperature
or temperature inside the control
cabinet is too high, or if there is
obstruction in the ventilation hole
of the control cabinet.
Check if there is any obstruction on
the heat sink or if the fan is
running.
Insufficient ventilation space
Check if the drive matches the
corresponding load
The drive has run 100% or more
than 100% of the rated output for a
long time
Unstable power
Load changes frequently

Fault Name
Heatsink overheating
Capacitance temperature exceeds the protection level
(oH2)
Action and Reset
Refer to the table below for oH2 level of each models
When capacitance temperature exceeds the protection level for more than 100
ms, oH2 error occurs
N/A
Manual reset
Reset when c
apacitance temperature is lower than oH2 error level minus (-) 10°C
Yes
1. Check ambient temperature.
2. Regularly inspect the ventilation hole of the control cabinet.
3. Change the installed place if there are heating objects, such as braking
resistors, in the surroundings.
4. Install/ add cooling fan or air conditioner to lower the temperature inside the
cabinet.
Remove the obstruction or replace the cooling fan.
Increase ventilation space of the drive.
1. Reduce the load
2. Reduce the carrier
3. Replace the drive with a larger capacity model.
Replace the drive with a larger capacity model.
