Heat generated during regeneration is not included in the servo amplifier-
generated heat. To calculate heat generated by the regenerative option,
refer to section 11.2.

Calculate the amount of heat generated by the servo amplifier with equation 10.2 below.
Servo amplifier-generated heat at rated output [W]
= Sum of servo amplifier-generated heat (B) + Servo amplifier-generated heat with servo-off (C) ·· (10.2)
Under the conditions in (1) in this section, according to table 10.3, the amount of heat generated by the
servo amplifier for each servo motor is as follows: HG-KR43 = 20 [W], HG-KR23 = 10 [W], HG-KR053 =
10 [W]. According to table 10.4, the amount of heat generated by the servo amplifier with servo-off is 25
[W]. Calculate the values with equation 10.2.
Servo amplifier-generated heat at rated output [W] = (20 + 10 + 10) + 25 = 65
Under the above conditions, the amount of heat generated by the servo amplifier is 65 [W].
