Three-phase AC motor jog control wiring.
2020年3月16日Control requirements: Basic low-voltage components can be used Ventilation fan motor suppliers https://www.chinakxdq.com/product/ventilation-fan-motor/ to perform forward rotation control of three-phase AC asynchronous motors. 2. Electrical schematic diagram of relay operation The electrical schematic diagram of relay-controlled three-phase AC asynchronous motor forward rotation relay button interlock operation is shown in Figure 1.1. 3. Electrical schematic diagram of relay operation The electrical schematic diagram of relay-controlled three-phase AC asynchronous motor forward rotation relay interlock operation is shown in Figure 1.2. First, make the schematic diagram Relay interlock as shown in Figure 1.3 Button interlock as shown in Figure 1.4 2. Input / output point allocation Input / output point allocation is shown in Table 1.5. III. Installation 1. The process is as follows: 1. Under the guidance, analyze the schematic diagram of the electrical control circuit. 2. Check the quality of each component with a multimeter. 3. Read the layout of electrical components, and install and fix electrical components accordingly. 4. Read the wiring diagram of the electrical installation and follow the wiring accordingly. (1)
The main circuit wiring should pay attention to the discrimination and selection of the main and auxiliary contacts of the contactor and the connection of the thermal relay; (2) When controlling the wiring of the circuit, pay attention to the resolution, selection and wiring of the normally open and normally closed contacts of the button. 5. Power on to check and clear the circuit fault. Three-phase AC motor jog control wiring. 未 When the power is off, use a multimeter resistance file to start to check whether the control circuit is correct. Turn on the power and operate the related buttons to verify the circuit’s operation. 2. Installation tools Tools: multimeter, needle-nose pliers, partial pliers, screwdriver, wire stripper, test pencil, etc. Device: one test mounting plate, several low-voltage electrical components, and several wires. 3. Make the component layout diagram After checking the components, install the electrical components on the control panel according to the prepared component layout diagram.
The electrical installation should be sturdy, meet the process requirements, and connect according to the wiring diagram. 4. Hardware debugging Use a multimeter to check the circuit. There must be no short circuit between the positive and negative poles of the power supply. Require power-on debugging only after checking for errors.
