Trigger action if a frequency threshold is exceeded
As a function of the current output frequency, the adjustable frequency threshold serves to trigger a certain function or set a digital output.
Parameter
Example for operating mode
In the following example, the digital output 1 is set to TRUE if the output frequency is higher than 20 Hz.
–
The analog input 1 is set as standard setpoint source.
–
Switch S1 starts the motor in forward direction of rotation. De-Asserting switch S1 stops the motor again.
