User Manual of EM760 High-Performance Inverter The analog input terminals AI1 to AI4 of the EM760 series inverter can be used as 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 ofthe terminal is less than 1V, its corresponding logic status will be invalid; ● When the input voltage ofthe terminal is greater than 3V, its corresponding logic status will be valid; ● When the input voltage ofthe terminal is within [1V, 3V], its corresponding logic status will remain unchanged.

6-26 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. 141 0: analog input 1: digital input (0 below 1V, 1 above 3V, the same as last time under 1-3V) Tens place: AI2 0: analog input 1: digital input (the same as above) Hundreds place: AI3 0: analog input 1: digital input (the same as above) Thousands place: AI4 (expansion card) 0: analog input 1:
