) Tool
For tightening the terminal, use a
commercially available small
screwdriver having a straight form that is
not widened toward the end as shown
right.
Caution:
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.
3 Grounding
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.
