When the Machine Stop Pushbutton is pressed, the PLC sends a STOP command to the drive. (Stop button is normally closed contact in this
example).
This rung transfers a frequency command from the PLC data table to the drive. A range of 0 to 32767 is equivalent to Zero
to Maximum Frequency. (In this example, the drive’s Frequency Select parameters are set to receive a frequency reference from the RIO Adapter.)
