(5) Other precautions

(a) Always use the dedicated stand-alone reactor (FR-CVL) as the power factor improving reactor. Do

not use the power factor improving AC reactor (FR-HAL) or Power factor improving DC reactor (FR-

HEL).

(b) The inputs/outputs (main circuits) of the FR-CV 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) or line noise filter (FR-BSF01, FR-BLF).

amplifiers should be 5 m or less, and the wiring must be twisted.

Note 1. This is the time when the protective function of the FR-CV 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.
