signal suffers severe interference, install a filter capacitor or ferrite magnetic core at
the analog signal source side. Connect the lead wire of the shield of the AI to the PE
terminal of the AC drive.

● When AI1 is used for voltage signal input, check whether the temperature
detection function of AI1 is invalid (invalid by default). When AI1 is used to collect
temperature data, set the AI temperature detection parameter in F6 group to the
sensor type that detects temperature.
● When AI1/AI2 is used for current signal input, the current flows to the AI1/AI2
terminal and the current flows from the GND terminal. Set related parameters
through the operating panel to switch to the current mode. For details, see the
software guide.
