In some intricate logic, a programmable logic controller uses to satisfy consumer requirements. Then the PLC sends the signal to your VFD According to the program logic.
This is referred to as Pulse Width Modulation or PWM. Picture that we could control the tension within a h2o line by turning the valve on and off at a large level of pace. Though This could not be realistic for plumbing methods, it really works very effectively for VFD’s.
For that we'd like an inverter. This is largely numerous IGBT’s, which might be switches that may turn on and off Tremendous-speedy. We’re planning to animate these working with simple switches as an alternative to IGBT’s to really make it easier to visualize. We’ll variety these switches as follows.
