DC bus over/under voltage protection
Bus voltage>overvoltage shutdown value: the compressor stops, then switches into the bus overvoltage protection.
Bus voltage<overvoltage recovery value, cancel the bus overvoltage protection.
Bus voltage<under voltage shutdown value: the compressor stops, then switches into the bus under voltage
protection.
Bus voltage<voltage recovery value, cancel the bus under voltage protection.
AC input over/under voltage protection
Drive comes with AC voltage detection, when input voltage is too low, the input current will be too high, damage can
occur
Input voltage<under voltage shutdown value, the compressor stops, then switches into the input under voltage
protection.
Input voltage>voltage recovery value, cancel the under voltage protection.
Drive comes with AC voltage detection, if the input voltage is too high, damage can occur.
Input voltage>over-voltage shutdown value, the compressor stops, then switches into the input overvoltage
protection.
Input voltage<over-voltage recovery value, cancel input over-voltage protection.
Communication error:
Drive priority detects the model code after power is on for 30 seconds .
Compressor type Model Code
TNB220FFEMC 0x02DC
TNB306FFEMC 0x02DD
If the model code is not within the model range or or the correct data is not received within the 30 seconds, the unit
will go into a communications failure mode and will shut down.
When the correct data is within the model code range the error will be canceled.
Note: For debug mode, when the model code is not within the range of models, sentenced to communication
failure; when the model code within the model range, then cancel the error
PFC switch value:
When PFC sampling current>PFC open switch current and the DC bus average voltage<PFC open switch voltage,
then opening PFC;
When PFC sampling current<PFC off switch current, off PFC.
