6.9.5 Function of the AI Terminals
The drive provides two AI terminals (AI1, AI2). An extra AI terminal (AI3) is provided by I/O
extension card.
Here use AI terminals as DI. 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 between
3 V and 7 V.
