3.3.4 AI
The AC drive is equipped with three multi‑functional analog input (AI) terminals by
default. To use AIs as DIs, the following parameters need to be set. When AI input
voltage is higher than 7 V, AI is in high level state. When AI input voltage is lower than
3 V, AI is in low level state. AI is in hysteresis state when AI input voltage is between 3
V and 7 V. The following figure shows the relationship between AI input voltage and DI
state.
