11. CHARACTERISTICS
11.2 Power supply equipment capacity and generated loss
(1) Amount of heat generated by the servo amplifier
Table 11.1 indicates servo amplifiers' power supply capacities and losses generated under rated load. For
thermal design of an enclosure, use the values in Table 11.1 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
maximum speed, the power supply capacity will be smaller than the value in the table, but the servo
amplifier's generated heat will not change.
