Automatic start / stop according to setting frequency
With this function, the converter starts when the setting frequency from analog
input is higher than the threshold, and stops when the setting frequency from
analog input is lower than the threshold. The threshold is set by parameter
E0.41 'Automatic start / stop frequency threshold'.
To use this function, follow the rules below:
●
The frequency setting source should be set to analog inputs.
●
The first and second run command source should be set to '0: Panel'.

●
When the setting frequency is higher than [E0.41], the frequency converter
starts and runs to the setting frequency automatically.
