For tightening the terminal, use a
commercially available small
screwdriver having a straight form that is
not widened toward the end as shown
If the diameter of screwdriver grip is too
small, tightening torque will not be able
to be achieved. Use the following recommended screwdriver or an
appropriate replacement (grip diameter: approximately 25mm (0.98")).
2 Wiring of Analog Output
→ For the terminal configuration, refer to Subsection 1.2.1
1 Use 2-core shielded twisted pair cable for the analog output lines, and
separate the analog output lines from other power lines or inductive lines.
2 The grounding resistance should be 100Ω or less.
Grounding should be performed as stated below.
• The grounding resistance should be 100Ω or less.
• Independent grounding should be performed for best results.
When independent grounding is not performed, perform "shared
grounding" of the following figure.
→ For details, refer to the FX3G Series User's
Manual - Hardware Edition.
• The grounding wire size should be AWG 22-20 (0.3-0.5 mm2).
• The grounding point should be close to the PLC, and all grounding wire
should be as short as possible.
