Table 1-5: Power Ratings and Dimensions of Liquid-Cooled Inverter Unit, Supply
Voltage 710 – 930V DC
Calculated
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
All power losses obtained using max. supply voltage I
th
and switching frequency of 3.6 kHz
and Closed Loop control mode. All power losses are worse case losses.
If some other mains voltage is used, apply the formula
to calculate the Liquid-Cooled drive electrical output power.
