Wiring of AI1
Analog signals at low levels can suffer from effects of external interference. To reduce
this effect, it is important to use shielded cables shorter than 20 m long to carry analog
signals.
Figure 3-18 Wiring for analog input 1
In applications where analog signals suffer from effects of severe external interference,
install a filter capacitor or a ferrite magnetic core at source of analog signal. The pig tail of
the shield must be connected to the PE terminal on the drive.

Wiring of AI2
When you select voltage input via AI2, use the same wiring method as AI1. When you
select current input via AI2, set jumper J9 to the I side.
