14.12 Frequency threshold for "Frequency threshold exceeded" trigger
As a funcon of the current output frequency, the adjustable frequency threshold serves to
trigger a certain funcon or set a digital output.

Threshold for the "Frequency threshold exceeded [70]" trigger.
•
The "Frequency threshold exceeded [70]" trigger is TRUE if the cur-
rent output frequency is higher than the set threshold.
•
The trigger can be assigned to a funcon or to a digital output.
Example for operang 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 direcon of rotaon. Switch S1 in the inial posion
stops the motor again.
