5.5.8 Analog input
S1 series inverter carries two analog input terminals (For model ≥4kW, they are AI1 and AI2.AI1 is
0–10V/0–20mA (voltage input or current input can be set by P05.50); AI2 is -10–10V; For models up
to 2.2kW,they are AI2 and AI3. AI2 is 0–10V/0–20mA(voltage input or current input can be set by
jumpers); AI3 is -10–10V) and two high-speed pulse input terminals. Each input can be filtered
separately, and the corresponding reference curve can be set by adjusting the reference corresponds
to the max. value and min. value.
