RUN blinks

Using an external switch to start the inverter, I set the frequency to 30 Hz. However, the RUN LED keeps rapidly blinking even when I set Pr.79 (Operation mode) to "3" or change it to "1" or "0".
I only use the terminals STF and SD.
MRS (Output stop signal) is not input to the terminal.

Rapid blinking of the RUN LED suggests that the frequency is not set correctly.
When the operation mode setting of Pr.79 is changed, the entrance point of the start signal also changes. Therefore, it is better to set the frequency again.

Set Pr.79 to "3" and set the frequency correctly.
