Notes: 1. Create a sequence that shuts off the main circuit power when either: An alarm occurs on FR-CV-(H) or the servo amplifier, or EM1 (Forced stop 1) is validated. 2. For the servo amplifier, create a sequence that switches the servo-on after FR-CV-(H) is ready. 3. Create a sequence that stops the servo motor with the emergency stop input to the servo system controller when an alarm occurs on FR-CV-(H). When the emergency stop input is not available in the servo system controller, stop the servo motor with the forced stop input to the servo amplifier as shown in the diagram. 4. Disconnect the short-circuit bar between P3 and P4 when using FR-CV-(H). 5. Set [Pr. PA04] to "0 0 _ _" to enable EM1 (Forced stop 1). 6. When wires used for L11 and L21 are thinner than those for L1, L2, and L3, use a molded-case circuit breaker. 7. When FR-CV-H is used, a step-down transformer is required if coil voltage of the magnetic contactor is in 200 V class. 8. Refer to relevant Servo Amplifier Instruction Manual for the examples of selecting wire sizes. 9. Use twisted wires for connecting the DC power supply between FR-CV-(H) and the servo amplifiers, and keep the wire length to a maximum of 5 m. 10. Inputs/outputs (main circuit) of FR-CV-(H) and the servo amplifier include high frequency components, and they may interfere with peripheral communication devices. In this case, the interference can be reduced with the installation of a radio noise filter (FR-BIF or FR-BIF-H) or line noise filter (FR-BSF01 or FR-BLF). 11. When using 7 kW or smaller servo amplifiers, disconnect the wiring of the built-in regenerative resistor. 12. For convenience of illustration, the diagram shows separate 24 V DC power supplies for input and output signals. However, the input and output signals can share a common power supply. 13. When using FR-CV-(H), be sure to use the following dedicated stand-alone reactor (FR-CVL or FR-CVL-H). Do not use a power factor improving AC reactor (FR-HAL or FR-HAL-H) or a power factor improving DC reactor (FR-HEL or FR-HEL-H) with FR-CV-(H).
