00: Regenerative option is not used
For servo amplifier of 100 W, regenerative resistor is not
used.
For servo amplifier of 0.2 kW to 7 kW, built-in regenerative
resistor is used.
01: FR-RC/FR-CV/FR-BU2
When you use FR-RC, FR-CV, or FR-BU2, select "Mode 2 (_ _
_ 1)" of "Undervoltage alarm detection mode selection" in [Pr.
PC20].
