What is power line communication (PLC)?
Power Line Communication (PLC) is now used in multiple end-equipment applications. A good example are grid applications, where the necessary data is communicated from one device to another using the power cable as transmission lines. Hence the name; Power line communication.
How do I connect a PLC to a drive?
You'll find it in all types of drives, it works as a dry contact. Just wire the PLC common to the drive common and the desired output of the PLC (typically a relay or transistor output) directly to the inverter terminal, and make sure to program the drive parameter to external control, so you can be able to send commands from the PLC.
How does a ths6222 solar inverter work?
Typically, multiple solar panels are attached on a string, each connected in series to reach the input voltage from a solar inverter. The required minimum sinking current is dependent on the total impedance on the PLC network and required signal peak voltage. The THS6222 features a bias setting input with 4 different modes.
Do I need a programming terminal for my inverter?
If you really don't need to use special functions from the inverter, other than normal commands like Start/Stop, Jog, or fixed speeds, then you could be better off using the programming terminal of the drive. You'll find it in all types of drives, it works as a dry contact.
