Calculation method of the amount of heat generated by the servo amplifier
Calculate the amount of heat generated by one servo amplifier from the following tables.
■Amount of heat generated by one servo amplifier at rated output
*1 The values stated for heat generated by the servo amplifier do not take into account the heat generated during regeneration. To
calculate heat generated by the regenerative option, refer to the following.
Page 160 Regenerative option
■Amount of heat generated by one servo amplifier for one direct drive motor
*1 The value inside ( ) applies when the torque is increased.
