User Manual of EM730 Series Inverter 3.3.2 Functions and wiring of control circuit terminals Table 3-3 Functions of Control Circuit Terminals 43 Category Terminal label Terminal name Function description Power supply 24V External power supply Supply 24V power to external devices, with the maximum output current of 100mA. COM Power grounding terminal Power grounding terminal of the external power supply, and common side of the digital input terminal Analog input ±10V Analog terminal power supply Supply 10V power to external devices. Maximum output current:
10.5±0.5V/20mA, usually as the power supply of the external potentiometer GND Analog power grounding terminal Grounding terminal of analog input and output AI1 Analog voltage input -10V to 10V, 50kΩ input impedance, bipolar analog voltage input AI2 Analog current/voltage input Current or voltage type Input range: 0/4-20mA or 0-10V Analog output M1 Analog voltage/current output 0-10V/0-20mA; output accuracy: ±2% Digital input port X1 Multi-function input terminal Program the corresponding terminals by setting function codes, to realize the input control of the set functions. The input terminal supports PNP and NPN input modes, and the default mode is the NPN input mode.
X5 can also be used as the high-frequency pulse input, with the input frequency up to X2 X3 X4 X5
