Cause
Check if the ambient temperature
or temperature inside the 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
corresponded loading
The drive has run 100% or more of
the rated output for a long time
Unstable power
The load changes frequently

Warning Name
Capacitor over-heat
The drive has detected over heat of the capacitor
warning (oH2)
Action and Reset
oH2 error level minus (–) 5°C
The oH2 warning occurs when the capacitor temperature is higher than oH2
warning level
N/A
Auto-reset
The drive auto-resets when the capacitor temperature is lower than oH2 error
level minus (–) 10°C
N/A
1. Check the 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. Decrease loading.
2. Decrease the carrier.
3. Replace with a drive with larger capacity.
Replace with a drive with larger capacity.
Install reactor(s).
Reduce the changes of the load.
