HVAC400X – APPLICATION MANUAL
P3.7.9 RESONANCE SWEEP (ID 1811)
You can use this parameter to activate the Resonance Sweep function.
The anti-resonance function slowly sweeps through frequencies from MinFreq to MaxFreq and back to MinFreq
with the ramp times set with this parameter. During this sweep, press the OK-button every time passing a
resonance range in order to tag where the range starts and ends.
If everything is fine the Prohibit frequency range parameters (in Prohibited Frequencies menu) are provided with
right information. If there is a different amount of tags during ramp-up compared to ramp-down, only an info
message is shown. The same will happen if the bands are not reasonable.
