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.
Amount of Heat Generated from the Inverter
This indicates the efficiency class
specified in IEC60034-30 “Efficiency
class of single speed, three-phase,
cage induction motors (IE-code).”
(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.)
