User Manual of EM760 High-Performance Inverter 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). Fig. 3-17 Wiring diagram - analog input voltage signals 3.3.3.2 Wiring of AI2 and AI3 terminals with analog current signal input:
When analog current signal input is selected for terminals AI2 and AI3, and the function code is setto F02.63(1/2) and F02.64 (1/2) 3.3.4 Wiring of multi-function input terminal The multi-functional input terminal ofthe EM760 inverter has a full-bridge rectifier circuit. 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 below: A. Use of internal power supply (+ 24Vdc) in B. Use of internal power supply (+ 24Vdc) in NPN mode PNP mode 56
