10.2 Power supply capacity and generated loss
(1) Amount of heat generated by the servo amplifier
Table 10.1 indicates servo amplifiers' power supply capacities and losses generated under rated load.
For thermal design of an enclosed type cabinet, use the values in the table in consideration for the worst
operating conditions. The actual amount of generated heat will be intermediate between values at rated
torque and servo-off according to the duty used during operation. When the servo motor is run at less
than the rated speed, the power supply capacity will be smaller than the value in the table, but the servo
amplifier's generated heat will not change.
