11. OPTIONS AND AUXILIARY EQUIPMENT
(b) Example of selecting the wire sizes
When connecting multiple servo amplifiers, always use junction terminals for wiring the servo amplifier
terminals P, N. Also, connect the servo amplifiers in the order of larger to smaller capacities.

11. 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.

Note 1. This is the time when the protective function of the FR-CV-(H) is activated. The protective function of the servo amplifier is
activated in the time indicated in section 10.1.
2. When connecting the capacity of connectable servo amplifier, specify the value of servo amplifier.
