Smart Power

DC bus over/under voltage protection

Bus voltage>overvoltage shutdown value, the compressor stop, then drive into the bus overvoltage protection.

Bus voltage<overvoltage recovery value, cancel the bus overvoltage protection.

Bus voltage<under voltage shutdown value, the compressor stop, then drive into the bus under voltage protection.

Bus voltage>voltage recovery value, cancel the bus under voltage protection.

AC input over/under voltage protection

Drive come with AC voltage detection, avoid the input voltage is too low, cause the input current is too high,

Input voltage<overvoltage recovery value, cancel input overvoltage protection.

Communication error

Drive priority detect the model code after power on .the 30s after power on is the time for the model code setting.

And need to complete the model code setting within this 30s, if setting completely, are not allowed to change.

Compressor type Model code

TNB220FFEMC 0x02DC

TNB306FFEMC 0x02DD

If the model code is not within the model range or the 30s not receive correct communication data, that the

communication failure, execute communications shutdown protection, while communication returns the

corresponding error code.

When PFC sampling current<PFC off switch current, off PFC.
