User Manual of EM730/EM730E Series Inverter 3.3.3 Wiring of analog input terminal 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 J8 on the control panel 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 inFig. 3-12-a. When the analog voltage input signal is sent by a potentiometer, the terminals AI1 and AI2 are connected as shown inFig. 3-12-b. In addition, F02.62 (AI1 input type) and F02.63 (AI2 input type) should be set according to actual needs (0: 0-10V; 1: 4-20mA; 2:
0-20mA; 4: 0-5V). EM730 AI1/AI2 -10VDC~10VDC/0~10VDC Near-end grounding GND PE of shielded cable (a) Fig.3-12 AI1/AI2 Terminal Wiring Diagram (b) Wiring of the input analog current signal of AI2 terminal: When the AI2 terminal is in the mode of analog current signal input, the switch J8 on the 41 keyboard port terminal The upper computer can also be connected through this port for background software debugging.
