Servo amplifier (2kW)
Overall wiring length 5m or less
First unit:
22mm2 assuming that the total of servo amplifier
capacities is 30kW since 15kW + 7kW + 3.5kW
+ 2.0kW = 27.5kW.
Junction terminals
Wire as short as possible.
Second unit:
14mm2 assuming that the total of servo amplifier
capacities is 15kW since 7kW + 3.5kW + 2.0kW =
12.5kW.
Third unit:
5.5mm2 assuming that the total of servo amplifier
capacities is 7kW since 3.5kW + 2.0kW = 5.5kW.
Fourth unit:
2mm2 assuming that the total of servo amplifier
capacities is 2kW since 2.0kW = 2.0kW.
Servo amplifier (15kW)
(5) Other precautions
(a) Always use the FR-CVL-(H) as the power factor improving reactor. Do not use the FR-BAL or FR-BE L.
(b) The inputs/outputs (main circuits) of the F R-CV-(H) and servo amplifiers include high-fr equency
components and may provide electromagnetic wave interf erence to communication equipment
(such as AM radios) used near them. In this cas e, interference can be reduced by installing th e
radio noise filter (FR-BIF-(H)) or line nois e filter (FR-BSF01, FR-BLF).
(c) The overall wiring length for connection of the DC power supply between the FR-CV-(H) and s ervo
amplifiers should be 5m or less, and the wir ing must be twisted.
