Note 1. This is the time when the protective function of the FR-CV-(H) is activated. The protective function of
the servo amplifier is activated in the time indicated in section 10.1.
2. The specified value is the power supply capacity of FR-CV-(H). The total power supply capacities of
the connected servo amplifiers are actually required.
