Note 1. When not using the phase detection terminals, fit the jumpers across RX-R, SX-S and TX-T. If the jumpers remain removed,
the FR-RC-H will not operate.
2. For the servo amplifier of 5 kW and 7 kW, always disconnect the lead wire of built-in regenerative resistor, which is connected
to P+ and C terminals. For the servo amplifier of 11 kW to 22 kW, do not connect a supplied regenerative resistor to the P+
and C terminals.
3. If disabling ALM (Malfunction) output with the parameter, configure up the power supply circuit which switches off the magnetic
contactor after detection of alarm occurrence on the controller side.
4. Between P3 and P4 is connected by default. When using the power factor improving DC reactor, remove the short bar
between P3 and P4. Refer to section 11.11 for details. Additionally, a power factor improving DC reactor and power factor
improving AC reactor cannot be used simultaneously.
5. For the power supply specifications, refer to section 1.3.
6. Set [Pr. PA04] to "0 0 _ _" to enable EM1 (Forced stop 1). Configure up the circuit which shuts off main circuit power with
external circuit at EM1 (Forced stop 1) off.
7. When wires used for L11 and L21 are thinner than wires used for L1, L2, and L3, use a molded-case circuit breaker.
8. This diagram is for sink I/O interface. For source I/O interface, refer to section 3.9.3.
9. The illustration of the 24 V DC power supply is divided between input signal and output signal for convenience. However, they
can be configured by one.
10. For selection of power factor improving AC reactors, refer to "Power Regeneration Converter FR-RC Instruction Manual
(IB(NA)66330)".
