1: The output of the inverter is a PWM wave, which contains more high-order harmonics. The variable frequency power sensor performs AC sampling on the input voltage and current signals, and then passes the sampled value through a transmission system such as cable and optical fiber and the digital input variable frequency power analyzer. The digital input variable frequency power analyzer performs ...
Overview of working principle:The main circuit is the power conversion part that provides voltage and frequency regulation power supply to the asynchronous motor. The main circuit of the inverter can be roughly divided into two categories: the voltage type is the inverter that converts the DC of the voltage source to AC, and the filter of the DC loop is the capacitor . The current type is a...
Frequency conversion energy savingInverter energy saving is mainly reflected in the application of fans and pumps. In order to ensure the reliability of production, all kinds of production machinery have a certain surplus when they are designed with power drives. When the motor cannot run under full load, in addition to reaching the power drive requirements, the excess torque increases the...
Given wayThe common frequency setting methods of frequency converter are: operator keyboard setting, contact signal setting, analog signal setting, pulse signal setting and communication method setting. These frequency setting methods have their own advantages and disadvantages, and must be selected and set according to actual needs.Related question and answerFrequency converterThe frequency...
1. OvercurrentOvercurrent is the most frequent phenomenon of inverter alarm.1.1 PhenomenonWhen restarting, it will trip as soon as the speed is increased. This is a very serious phenomenon of overcurrent. The main reasons are: load short circuit, mechanical parts stuck; inverter module damaged; motor torque is too small and other phenomena caused.It jumps after power on. This phenomenon cannot be ...
