More Information
Summary:The utility model discloses a frequency converter control system which comprises a PLC control module connected with a frequency converter through a data serial port, the PLC control module is further connected with an instruction communication module, and the instruction communication module comprises a wireless signal receiver used for receiving control instructions remotely issued by a background control center. An output signal of the wireless signal receiver is sequentially processed by a matching amplification adjusting circuit and a power frequency noise reduction circuit and then is sent to the PLC control module; according to the utility model, the instruction communication module is designed in the frequency converter control process aiming at the particularity of the refractory material production environment, thereby effectively preventing the fluctuation of a control instruction signal in a wireless channel due to clutter invasion, guaranteeing the receiving effectiveness of a remote control inst
