How to Maintain a frequency Inverter (AC drive)? (part 1)
How to Maintain a frequency Inverter? (part 1)
How to maintain a frequency inverter (AC drive, variable frequency drive, VSD)? Is it a complex job? Challenging? Maintaining a frequency inverter (AC drive) is easier than you might think. By integrating some simple, logical steps into your preventative maintenance program, you can ensure that the drives provide many years of trouble-free service.
Before looking at those simple steps, let's quickly review what is a frequency inverter (AC drive) and how it works?
An AC drive (frequency inverter, VFD) controls the speed, torque and direction of an AC induction motor. It takes fixed voltage and frequency alternative current (AC) input and converts it to a variable voltage and frequency AC output. These articles: What exactly is ac drive (frequency inverter) and Understanding Frequency Inverter introduce a more detailed description of frequency inverter (VSD) concepts and operating principles.
In a very small frequency inverter (AC drive), a single power pack unit may contain the converter and inverter.
Fairly involved control circuitry coordinates the switching of power devices, typically through a control board that dictates the firing of power components in the proper sequence. A microprocessor or Digital Signal Processor (DSP) meets all the internal logic and decision requirements.
From this description in earlier post, you can see a frequency inverter (variable frequency drive, VFD) is basically a computer and power supply. Of course the same safety and equipment precautions you'd apply to the computer and to the power supply apply. Frequency inverter (variable frequency drive, VFD) maintenance requirements fall into three basic categories:
keep the drive clean;
keep the drive dry;
keep the connections tight.
Let's look at each of these 3 basic categories step by step.
Keep the Drive (frequency inverter) Clean
Most frequency inverter (variable frequency drive, VFD) falls into the NEMA 1 category (side vents for cooling airflow) or NEMA 12 category (sealed, dust-tight enclosure). The AC drives (VFDs) that fall in the NEMA 1 category are susceptible to dust contamination. Dust on the drive hardware of NEMA 1 category can cause a lack of airflow, resulting in diminished performance from heat sinks and circulating fans (Refer to figure 1).

how can i select a correct size of VFD?
hi, we have using a 3phase, 0.2 kw, 0.48 amps, AC drive motors 2 nos.(total-0.4 kw). so how can i select a correct size of VFD. Please tell me the best solution.
Just get a VFD equal to the rating of your existing unit. Higher VFD's will cost you more money. Recheck the load current of your existing unit and see if it is within 0.48 amperes.If your current is within the range of the full load name plate rating, your VFD still be should be 0.2 kw.
