Regenerative
option
_ _ x x Regenerative option selection
Used to select the regenerative option.
Incorrect setting may cause the regenerative option to burn.
If a selected regenerative option is not for use with the servo amplifier, [AL. 37
Parameter error] occurs.
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. PC27].
