11.4 FR-RC-(H) power regeneration converter
POINT
When using the FR-RC-(H) power regeneration converter, set [Pr. PA04] to
"0 0 _ _" to enable EM1 (Forced stop 1).
When using the FR-RC-(H) power regeneration converter, refer to "Power
Regeneration Converter FR-RC Instruction Manual (IB(NA)66330)".
When using the FR-RC-(H) power regeneration converter, set [Pr. PA02] to "_ _ 0 1" and set [Pr. PC20] to
"_ _ _ 1".
(1) Selection
The converters can continuously return 75% of the nominal regenerative power. They are applied to the
servo amplifiers of the 5 kW to 22 kW.
