1.4.1 - Electrical characteristics
Ico
: Continuous output current.
Pout
: Output power.
Imax (60s)
: Maximum output current, available for 60 seconds every 600 seconds.
Heavy duty
: For heavy-duty constant torque machines (presses, grinders, hoisting, etc) and all applications where significant
inertia has to be accelerated quickly (centrifuges, translation of travelling cranes, etc).
Normal duty
: For normal-duty constant torque or centrifugal torque machines (fans, compressors, etc).
CAUTION: In its factory setting, the drive operates with a switching frequency of 3 kHz.
400 V to 460 V 3-phase supply
Switching frequency = 3 kHz - ambient temperature ≤ 40°C - altitude ≤ 1,000 m.
