POINT
When using FR-RC, set [Pr. PA04] to "0 0 _ _" to enable EM1 (Forced stop 1).
When using the power regenerative converter, set "_ _ 0 1" in [Pr. PA02].
(1) Selection example
The converters can continuously return 75% of the nominal regenerative power. They are applied to the
servo amplifiers of the 5 kW to 7 kW.
