Wiring
(1) Use twisted pair shield cables (0.2mm
To protect the cables from noise, run them away from any source of noise (e.g. the main circuit
and power voltage).
Wiring Length
Within 10m
At least 2 cables
Within 20m
At least 4 cables
Within 100m *
At least 6 cables
* When differential driver is set and a wiring length is 30m or more
The wiring length can be extended to 100m by slightly increasing the power by 5V (approx. 5.5V) using six or more cables with
gauge size of 0.2mm
power supply specifications of encoder.
To reduce noise of the encoder cable, earth (ground) the encoder shielded cable to the enclosure (as near
as the inverter) with a P clip or U clip made of metal.
REMARKS
· For details of the optional encoder dedicated cable (FR-JCBL/FR-V7CBL), refer to page 13.
· The FR-V7CBL is provided with a P clip for earthing (grounding) shielded cable.
