EM630/TC6A Closed-Loop Vector Hoist Inverter User Manual 3.3.3 Analog Input Terminal Wiring 3.3.3.1 Wiring Terminals AI1, AI2 and AI3 Through Analog Voltage Signal: When selecting the analog voltage signal input for terminals AI2 and AI3, configure the voltage mode through switches S4 and S5 of the terminal block. See Figure 3–13. V AI2 I V I AI3 S4 S5 Figure 3–13 Configuring Voltage Modes with S4 and S5 When the analog voltage input signal is powered by the external power supply, terminals AI1, AI2 and AI3 are wired as Figure 3–14-a. When the analog voltage input signal is generated by potentiometer, terminals AI1, AI2 and AI3 are wired as Figure 3–14-b.
