Trip level for mains undervoltage.
The power part of the DCS400 can operate on a
supply voltage of 230…500 V. A parameter setting
based on this is therefore not possible. The
minimum allowable mains voltage is calculated from
the parameter nominal motor voltage Arm Volt Nom
(1.02). If the mains voltage falls below the
calculated voltage the drive switches off and gives
an alarm F09.
The minimum voltage is calculated with
U
mains
≥
Ua / (1,35 x cos alpha)
cos alpha: 4Q = 30° = 0,866
2Q = 15° = 0,966
4Q: U
mains
≥
Ua / (1,35 x 0,866)
2Q: U
mains
≥
Ua / (1,35 x 0,966)
This parameter defines an additional safety margin
over the minimum allowable mains voltage.
