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 zero torque 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.

Note:1. Note that the power supply capacity will vary according to the power supply impedance.

2.Heat generated during regeneration is not included in the servo amplifier-generated heat. To calculate heat generated by the regenerative brake option, use Equation 12.1 in Section 12.1.1.
