A computer programmer, or coder, creates the code that computers and software programs need to function. Computer programmers also test programs to make sure they are working properly. They look for errors in the code and resolve them. Computer programmers use computer languages, such as C, C++, Java, PHP, Lisp and Python to translate designs created by software developers or system architects into instructions for computers to follow.

Want to switch your career in to Variable Frequency Drive (VFD)? Looking for interview question and answers to clear the Variable Frequency Drive (VFD) interview in first attempt. Then we have provided the complete set of Variable Frequency Drive (VFD) interview question and answers on our site page. To be precise about Variable Frequency Drive (VFD). A variable-frequency drive is a type of adjustable-speed drive used in electro-mechanical drive systems to control AC motor speed and torque by changing motor input regularity and voltage. If you are good at Variable Frequency Drive (VFD) concepts then there are various leading companies that offers job in various roles like Service Engineers for Variable Frequency Drives (vfd) & Control, Senior Test Engineer – Product Testing, Vertical Head,along with that there are many other roles too.

Q. Can a variable frequency drive be used for a fan application, blower application or a pump application?
Joliet Technologies is dedicated to providing our customers and website visitors with quality information about our products and services. As well as helpful information you can use to make well informed decisions regarding your drive needs.
Q. Is it possible to use the same soft starter to start two MV induction motors?
Q. What’s the difference between a variable frequency drive (vfd) and a variable speed drive (vsd)?
Q. From a website visitor: What is the problem if I use a 15hp vfd for a 1hp induction motor speed control? I set data of the 1hp motor in the 15hp vfd, is there any problem using it?
Suitability of the motors – the motors need to be rated for inverter-obligation to withstand the higher electric stresses drives can impose. Some older cars had been no longer constructed to withstand those stresses and can fail prematurely. Distance of automobiles from VFD’s – the VFD’s will result in voltage transients at the load connectors. If these connectors are too lengthy (manufacturers regularly recommend preserving motor lead duration to 50m or less), the voltage on the motor terminals can also increase to several factors above nominal, which also can cause premature motor failure. VFD installation region and environmental situations – this could decide the form of enclosure and conditions underneath which the VFD’s will perform. VFD’s which must face up to excessive moisture, temperature swings, or dust can fail in advance and should be included through definitely rated enclosures. Plc Scada Interview Questions Question 24. How Can A Variable Speed Drive Improve Our Production?
Yes, its miles feasible to start multiple automobiles from a unmarried tender-start. Typically, the motors are began sequentially and are identically rated. In an average MV software, extra contactor shelves are connected and manipulate-tied to the tender-start. Once the primary motor comes up to the mark, the smooth-start “Switches” to manipulate the subsequent motor in the series.
Use of a DC cap throughout alternator terminals is regularly achieved to clear out alternator whine (noise) resulting from voltage ripple, the “AC” factor of rectified DC output. When the capacitance is well established and coupled to the frequency of the noise, it gives a low-impedance path to “divert” the voltage ripple to floor.
