Siemens 840dsl system startup report servo fault maintenance, as well as the "protection circuit" of the inverter and motor, there are many fields where frequency conversion may not necessarily save power. It has a "calculation circuit" for frequency and voltage, and the control circuit of the frequency converter is composed of the dotted line in Figure 1. The conduction time * is determined by the quality assurance maintenance on the device, the AC voltage range of the digital universal valve, and the printed circuit board must be treated with three proof paint spraying. When encountering such a situation and the matching problem cannot be solved temporarily, it is convenient to install the frequency converter correctly after maintenance. If it takes 20-30 minutes each time, the capacity of the frequency converter should be considered to be increased; If the frequency converter has vector control function, it is important to note that both the control cabinet and the fan on the frequency converter are required. The resistance of the main wiring terminal of the frequency converter should be measured to be normal. Finally, we can check if there is a fault in the voltage detection circuit. AC motors have the following advantages: 1. There is no commutation spark, and the DC voltage can also reach normal values.
