User Manual of EM730 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 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. 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). 44 100kHz. Multi-function digital output Y1 Open collector output terminal It can be programmed as the multi-function output terminal. YCM Common side of Y terminal The common side YCM of Y terminal and the common side COM of the digital input terminal are independent of each other. Communication A+ RS485 communication terminal positive terminal of RS485 differential signal A- negative terminal of RS485 differential signal Relay output EA Relay output terminal EA-EC: Normally open EB-EC:
Normally closed EB EC External keyboard port RJ45 External keyboard terminal For the external operation panel The upper computer can also be connected through this port for background software debugging.
