AC Input Current
Note!
The Input current of the Drive depends on the operating state of the connected motor. The tables (chapter
3.4) shows the values corresponding to rated continuous service, keeping into account typical output power
factor for each size.
3.5 AC Output
Type 2040 2055 2075
Pn mot (recommended motor output):
@ Uln=400Vac; fsw=default [kW] 4 5.5 7.5
@ Uln=460Vac; fsw=default [Hp] 5 7.5 10
U2 Max output voltage [V] 0.98 x Uln (AC Input voltage)
f2 Max output frequency [Hz] 500 Hz (V/f)
In Rated output current::
@ Uln=400Vac; fsw=default [A] 10.1 13 17.7
@ Uln=480Vac; fsw=default [A] 8.6 11.7 14.9
Switching frequency fsw (Default) (5) [kHz] 8
Switching frequency fsw (higher) (5) [kHz] 10,12
Iovld [A] Short term overload current. 170% of In for 10s on 100s.
Derating factor
Kv (1) 0.87
Kt (2) 0.8
Kf (3) 0.85; 0.7
Kalt (4) 1.2
Braking unit intervention threshold (@ 380 V - 480 V) [Vdc] ON = 780 Vdc, OFF= 770 Vdc (6)
(1): Derating factor for mains voltage at 460 Vac
(2): Derating factor for 50°C ambient temperature (2 % each °C > 40 °C)
(3): Derating factor for higher switching frequency
(4): Derating factor for installation at altitudes above 1000 meters a.s.l.. Value to be applied at each 100 m increase
above 1000 m
(5) It is possible to set a xed switching frequency (from 4 to 12 kHz depending on size and with derating where applicable).
Otherwise it is possible to set a variable switching frequency between two levels (hswf and Iswf) dened according
to size, heat sink temperature and stator frequency:
Type Higher sw frequency
[kHz]
Lower sw frequency
[kHz]
F out
[Hz]
T
[°C]
2040 8 4 3 64
2055 8 4 3 60
2075 8 4 3 60
The output of the Drive is ground fault and phase to phase output short protected.
Nota!
The connection of an external voltage to the output terminals of the Drive is not permissible! It is allowed to
disconnect the motor from the Drive output, after the Drive has been disabled.
The rated value of direct current output ( Icont ) depends on the ambient temperature ( K
T
) and the switching frequency
( Kf) if higher than the default setting:
Icont = In x Kt x Kf
(6) With parameter P.344 “BU threshold factor” is possible change the threshold in use:
BU-On In use (Vdc) = BU-On (Vdc) * P.344 / 100
