Operating Instructions ACU
16.3.2 Setting Frequency
If Operation Mode 4 - “Setting Frequency” is selected for a digital output , the relevant output will
be active once the actual value Stator Frequency 210 is higher than the value of Setting Frequency
510.
The output will be switched again once the Stator Frequency 210 drops below the value “Setting
Frequency 510 minus Setting Frequency Off Delta 517”. Once the output stages are switched off
(e.g. via STO), the digital signal “Setting Frequency” is set to zero, regardless of the actual
frequency.
Signal source 164 - "Setting frequency" can be linked to the functions of the frequency inverter.
Setting Frequency Off Delta
Once Setting Frequency Off Delta 517 > Setting Frequency 510, the output will not
turned off anymore after first activation. Make sure you use suitable values during
parameterization.
