Table 1-2: Power Ratings and Dimensions of Liquid-Cooled Drive, Supply Voltage
380 – 500V AC (Continued)
I
th
= Thermal maximum continuous RMS current. Dimensioning can be done according to
this current if the process does not require any overloadability or the process does not
include any torque ripple.
I
L
= Low overloadability current. Allows +10% torque ripple. 10% exceeding can be
continuous.
I
H
= High overloadability current. Allows +50% torque ripple. 50% exceeding can be
continuous.
All values with cosϕ = 0.83 and efficiency = 97%.
c/a/T: c = power loss into coolant; a = power loss into air; T = total power loss; power losses
of input chokes not included. All power losses obtained using max. supply voltage and
switching frequency of 3.6 kHz.
If some other mains voltage is used, apply the formula
to calculate
the Liquid-Cooled drive output power.
The enclosure class for all Liquid-Cooled drives is IP00.
