User Manual of A90 Series Inverter digital input terminals. You only need to set the corresponding bit to 1. To use the AI2 terminal as a digital terminal, you only need to set F02.31=xx1x. The analog input and digital logic conversion are as follows: When the input voltage of the terminal is less than 1V, its corresponding logic status will be invalid; When the input voltage of the terminal is greater than 3V, its corresponding logic status will be valid; When the input voltage of the terminal is within [1V, 3V], its corresponding logic status will remain unchanged. Logic 1 0 0 V 1V 3V Voltage Fig.
7-10 Correspondence between Analog Input Terminal Voltage and Current Logic Status If it is used as an analog input terminal, the filter time and corresponding offset curve can be set via F02.32 to F02.60. The terminals AI1 to AI4 can be set separately. 147 Function Default Function code name Parameter description Unit Attribute code setting F02.32 Options of analog input curve Ones place: Options of AI1 curve 0: curve 1 1: curve 2 2: curve 3 3: curve 4 Tens place: AI2 curve selection 0: curve 1 3210D ○
