11.4 Power regeneration converter
POINT
When using the FR-RC-(H) power regenerative converter, refer to "Power
Regeneration Converter FR-RC Instruction Manual (IB(NA)66330)".
When using the power regeneration converter, set "
01" in parameter No.PA02.
(1) Selection
The converters can continuously return 75% of the nominal regenerative power. They are applied to the
servo amplifiers of the 5k to 22kW.
