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 resistor connected to P terminal
and C terminal.
3. For sink input-output interface. Refer to section 4.8.3 for source input-output interface.
4. When using the servo amplifier of 11k to 22kW, always connect P
improving DC reactor, refer to section 14.11.
5. 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.
6. Stepdown transformer is required for coil voltage of magnetic contactor more than 200V class in 400V class servo amplifiers.
7. Refer to section 1.2 for the power supply specification.
