Generated Loss - Mitsubishi Electric MELSERVO MR-J5 Series User Manual

Generated loss

Servo amplifier generated heat
The following tables indicate the losses generated by servo amplifiers under rated load. For thermal design of an enclosed
type cabinet, use the values in the tables in consideration for the worst operating conditions including environments and
operation patterns. 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.
