Generated loss
Amount of heat generated by the drive unit
The following tables indicate the losses generated by drive units under rated load. For thermal design of an enclosed type
cabinet, use the values in the tables in consideration for the harshest conditions with regard to the environment and operation
pattern. The actual amount of generated heat depends on the frequency of operation and will be between the "At rated output"
and "At servo-off" values.
