Code Parameter Min Max Unit Default ID Description
P3.22.2.14 Damping sensitivity 5 50 V 10 1943
Amplitude of oscillation to be
recognized
P3.22.2.15 Damping time 3 10 s 4 1944
Time for the oscillations on DC
voltage
P3.22.2.16 Minimum DC voltage
Varies

Varies V Varies 1995
If the DC-link voltage goes below
this threshold, the undervoltage
regulator will quickly decrease the
output frequency. In case it results
lower than the programmed
minimum reference, the drive
stops with warning 60. The value
depends on the voltage range.
5)
The minimum value is 300 V and it is valid for RSI 380-500 V AC when the drive is manufactured after June 2020. For older RSI
380-500 V AC, the minimum value is 400 V.
