18' Commercial Tower Models (3000 - 4800)
The variable frequency drive controls speed of the sweep arms for all tower dryers. The communication from the HMI to the PLC then correlates to the variable frequency drive. It is important to note that some of the parameters listed below will vary such as voltage, amperage and motor speed. These values should match the motor name plate.
Dip switches must both be set to ON for SIEMENS S7-1200.
If programmed by hand, upload to panel, then download full set to drive.
