Generated Loss - Mitsubishi Electric 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. The actual amount of generated
heat will be intermediate between values at rated output and servo-off according to the duty used during operation.
