7.4.2 Wiring of Control Circuit Terminals
Wiring for AI
因Weak analog voltage signals are prone to external interference. Therefore, a
shielded cable is typically required, and the wiring distance should be as short as
possible (within 20 m), as shown in "
Figure 7–34 Wiring for AI " on page 137 . In
scenarios where analog signals receive severe external interference, install a filter
capacitor or a ferrite core on the analog signal source side, as shown in "
Figure 7–35
Grounding the shield of AI1
" on page 137 . Connect the lead wire of the shield of the
analog input terminal to the PE terminal of the AC drive.
