Appendix A – ACS/ACC 600 Technical Data
A-2 601/604/607 US Supplement
Current ratings are for operation up to 1000m (3300 ft)
altitude and 40°C(104°F) ambient temperature (35° C/95°F
for models ACx 601-0025-2, ACx 601-0050-2 and ACx 601-
0070-2 in IP54 enclosures). For high temperature and
altitude derating, see pages A-3 to A-7.
The current ratings are the same regardless of the supply
voltage within one voltage range. The rated current of the
ACx 60x must be higher than or equal to the rated motor
current to achieve the rated motor power given in the table.
Note 1: The maximum allowed motor shaft power is limited
to 1.5 · P
hd
. If the limit is exceeded, the motor torque and
the I
hdmax
2 s current is automatically restricted. The
function protects the input bridge of the ACx 600 against
overload.
Note 2: The load capacity (current and power) decreases if
the installation site altitude exceeds 1000 meters (3300 ft.),
or if the ambient temperature exceeds 40 °C.
Usually dv/dt filters are not needed at the output of 240 V
units.
