(5) Other precautions
(a) When using the FR-CV-(H), always install the dedicated stand-alone reactor (FR-CVL-(H)). Do not use
the power factor improving AC reactor (FR-BAL-(H)) or power factor improving DC reactor (FR-BEL-(H)).
(b) The inputs/outputs (main circuits) of the FR-CV-(H) and servo amplifiers include high-frequency
components and may provide electromagnetic wave interference to communication equipment
(such as AM radios) used near them. In this case, interference can be reduced by installing the
radio noise filter (FR-BIF-(H)) or line noise filter (FR-BSF01, FR-BLF).
(c) The overall wiring length for connection of the DC power supply between the FR-CV-(H) and servo
amplifiers should be 5m or less, and the wiring must be twisted.
Wire as short as possible.

First unit:
22mm assuming that the total of servo amplifier
2
capacities is 30kW since 15kW + 7kW + 3.5kW
+ 2.0kW = 27.5kW.
Second unit:
14mm assuming that the total of servo amplifier
2
capacities is 15kW since 7kW + 3.5kW + 2.0kW =
12.5kW.
Third unit:
5.5mm assuming that the total of servo amplifier
2
capacities is 7kW since 3.5kW + 2.0kW = 5.5kW.
Fourth unit:
2mm assuming that the total of servo amplifier
2
capacities is 2kW since 2.0kW = 2.0kW.
