200 V class
*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
will not operate.
*2 When using the servo amplifier of 7 kW or less, make sure to disconnect the wiring of built-in regenerative resistor (5 kW or less: P+ and
D, 7 kW: P+ and C). 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. 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 the following.
 Page 30 Servo amplifier standard specifications
*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 shows sink I/O interface. For source I/O interface, refer to the following.

*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)".
