User Manual of A90 Series Inverter Note: 1) For the A90-4T017B model and below, connect the terminals COM and GND internally. 3.3.3 Wiring of analog input terminal 3.3.3.1 Wiring of AI1 and AI2 terminals with analog voltage signal: When the AI2 terminal is in the mode of analog voltage signal input, the switch S2 on the terminal block is set to the voltage mode, as shown in Fig. 3-12. When the analog voltage input signal is powered by an external power supply, the wiring of terminals AI1 and AI2 is shown in Fig. 3-12-a. When the analog voltage input signal is sent by a potentiometer, the terminals AI1 and AI2 are connected as shown in Fig. 3-12-b.
