User’s Guide for EM760 series high-performance vector inverter 3.4 Wiring of analog input terminal 3.4.1 Wiring of AI1, AI2 and AI3 terminals with analog voltage signal:
When analog voltage signal input is selected for terminal AI1 and the function code is set to F02.62 (0/3), corresponding input is (0~10V/-10~10V) When analog voltage signal input is selected for terminal AI2 and the function code is set to F02.63 (0), corresponding input is (0~10V) When analog voltage signal input is selected for terminal AI3 and the function code is set to F02.64 (0), corresponding input is (0~10V) When the analog voltage input signal is powered by an external power source, wiring of AI1, AI2 and AI3 are performed as shown in the following Figure (a).
When the analog voltage input signal is a potentiometer, the wiring of AI1, AI2 and AI3 terminals is as shown in Figure (b).

The PLC terminal is a common terminal of X1 to X7, through which the current may be forward (NPN mode) or reverse (PNP mode). Thus, the external connection of the terminals X1 to X7 is flexible. Typical wiring is shown in Fig. 3-7. A. Use of internal power supply (+24Vdc) in NPN mode B. Use of internal power supply (+24Vdc) in PNP mode 26
