Auto When Pr.04-50=0, oH3 is a warning and will be automatically cleared.
Manual When Pr.04-50=1, oH3 is a fault and must be reset manually.
Resets when PTC input level is lower than [Pr.04-51 – 5].
If oH3 is a warning, it will not be recorded.
If oH3 is a fault, it will be recorded.
Clear the motor lock status.
Decrease the loading.
Replace with a motor with larger capacity.
Change the installed place if there are heating devices in the surroundings.
Install/ add cooling fan or air conditioner to lower the ambient temperature.
Replace the fan.
Decrease low-speed operation time.
Change to dedicated motor for the drive.
Increase the motor capacity.
Increase setting values for Pr.00-71–Pr.00-78 (accel./ decel. time).
Decrease the setting values for Pr.03-51–Pr.03-56 (V/F curve).
