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. When using servo amplifiers of 5kW and 7kW, always remove the lead of built-in regenerative brake resistor
connected to P terminal and C terminal.
3. When setting not to output Trouble (ALM) with parameter change, configure power supply circuit for turning magnet
contactor off after detecting an occurrence of alarm on the controller side.
4. Always connect P

(For 11k to 22kW, connect P-P

). (Factory-wired.) When using the power factor improving DC
reactor, refer to Section 11.13.
For 400 VAC class, the stepdown transformer is required.
