12. OPTIONS AND AUXILIARY EQUIPMENT
(5) Other precautions
(a) Always use the FR-CVL(-H) as the power factor improving reactor. Do not use the FR-BAL or FR-BEL.
(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.
