For the amount of heat generated from the Inverter, refer to the power losses of the Inverter provided in
https://industrial.omron.eu/en/company-info/environmental/ecodesign-directive.
1 When you access the above URL, the “Ecodesign Directive” page is displayed.
2 Download the ecodesign data for RX, RX2, and MX2 Series from the above website and
display the files in the MX2-EV2 folder.
3 Open the PDF file for the model for which you want to know the power losses to display
the power loss data as shown below.
4 In the figure above, the table on the left shows the power loss of the Inverter at each
point indicated by the numbers on the frequency - relative torque-producing current
graph on the right.
5 Determine the amount of heat generated from the operating conditions and power losses
of the Inverter.
This indicates the efficiency class
specified in IEC60034-30 “Efficiency
class of single speed, three-phase,
(1) shows the power losses
of the Inverter at motor
rated frequency × 90% and
load of 100% (ND rating).
(In the example on the left,
(1) is 0.01 kW.)
