Note 1. Note that the power supply capacity will vary according to the power supply impedance. This value is
applicable when the power factor improving AC 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 option, refer to section 11.2.
