Jumper Function and setting description Factory setting
CN2
AI3 analogue input channel can select voltage or current signal:
When pin 1 and pin 2 of the CN2 are short-circuited, AI3 channel
inputs voltage singal;
When pin 2 and pin 3 of the CN2 are short-circuited, AI3 channel
inputs current singal.
CN3
AI4 analogue input channel can select voltage or current signal:
When pin 1 and pin 2 of the CN3 are short-circuited, AI4 channel
inputs voltage singal;
When pin 2 and pin 3 of the CN3 are short-circuited, AI4 channel
inputs current singal.
Note: Need to short-circuits pin 2 and pin 3 of the CN4.
CN4
AI4 analogue input channel can select thermistor:
When pin 1 and pin 2 of the CN4 are short-circuited, AI4 by
external thermistor as motor overheat detection signal input;
When pin 2 and pin 3 of CN4 are short-circuited, AI4 channel
inputs reference analogue.
9.1.3 Terminal Connection of Extension I/O card
Wiring of analogue input terminal
AI3 with the AI2 of control terminal has same wiring, see analog input terminal of the section 4.4.4
Control Terminal Connection, shown as Figure 4-20.
When AI4 is used as reference analogue input terminal, the wiring is shown as Figure 9-3 and
AI4+ as analogue signal input.
