Frequency setting

I set Pr.79 (Operation mode) to "3" (Combined operation mode), and short-circuit the terminals STF and SD from an external source. The frequency is set with external 4 to 20 mA DC input as well as the setting dial on the operation panel.
The frequency set using the setting dial does not become effective when the terminals AU and SD are opened.
The LED displays "0.00" and the mode LEDs "PU" and "EXT" are turned OFF.

Answer

Normally, any of the PU, EXT, or NET LED turns ON.

Check if the parameter unit FR-PU04/FR-PU07 or operation panel FR-PA07 is externally connected to the PU connector.
If it is, disconnect it. The LED turns ON.

If any of these is connected, the frequency setting command source is switched to FR-PU04/FR-PU07/FR-PA07, and the setting dial on the operation panel becomes inactive.
