Note 1. Note that the power supply capacity will vary according to the power supply impedance. This value assumes that the power
factor improving reactor is not used.
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 13.1 in Section 13.1.1.
