• To reduce noise of the encoder cable, earth (ground) the encoder's shielded cable to the enclosure (as close as possible
to the inverter) with a metal P-clip or U-clip.
• When one encoder is shared between the FR-A8AP and CNC (computerized numerical controller), its output signal should
be connected as follows. In this case, the wiring length between the FR-A8AP and CNC should be as short as possible,
within 5 m.
NOTE
• For the details of the optional encoder dedicated cable (FR-JCBL/FR-V7CBL), refer to
• The FR-V7CBL is provided with a P-clip for earthing (grounding) shielded cables.
