(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.
Wire as short as possible.

Servo amplifier (15kW)
First unit:
P
22mm assuming that the total of servo amplifier
2
N
capacities is 30kW since 15kW + 7kW + 3.5kW
+ 2.0kW = 27.5kW.
Servo amplifier (7kW)
Second unit:
P
22mm assuming that the total of servo amplifier
2
N
capacities is 15kW since 7kW + 3.5kW + 2.0kW =
12.5kW.
Servo amplifier (3.5kW)
Third unit:
P
8mm assuming that the total of servo amplifier
2
N
capacities is 7kW since 3.5kW + 2.0kW = 5.5kW.
Servo amplifier (2kW)
Fourth unit:
P
3.5mm assuming that the total of servo amplifier
2
N
capacities is 2kW since 2.0kW = 2.0kW.
