14.3 Trigger acon if a frequency threshold is exceeded
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.

Frequency threshold
(Freq. threshold)
0.0 ... [0.0] ... 599.0 Hz
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.
