How to use powerflex 4m  VFD : -                                            This is front view of power flex 4m allen-bradly vfd. This vfd generally used up to 0.2 K.W (0.25 H.P) TO 11 K.W (15 H.P). choose your use of vfd by different catlog no. in this model of vfd.  (Note- choose proper vfd. check the voltage and kw rating otherwise the vfd can be hazardous) Installation : - This model of allen bradly is easy to install. behind the vfd there is arrangement to adjust it on C-channel in panel. so its easy to install. First i would suggest to install proper size of MCB to supply the vfd. Check the proper voltage level for supply. Give all the phase to L1, L2 L3 respectively on the top of VFD. Supply on the power and turn on the VFD. Check the VFD and after that i would suggest to connect the motor. Use the manual of powerflex ...

POWER FLEX 753 ALLEN- BRADLY :- This video is about to solve the problem in allen-bradly power flex 753 VFD. VFD showing heat sink over temp fault.  To see vfd temp in power flex 753 go to the parameter no 943-942 This parameters shows the temperature of vfd and IGBT respectively. DRIVE TEMP PCT is fault 943 which shows the indication operating temperature of the drive power section(heat-sink) in percentage of minimum heat-sink temperature. Sollution:- To solve this problem first check the cooling fan of vfd is working or not.   One of the cooling fan is exactly under the sensor. if the fan is failed . then the sensor may sense the temperature and trip the vfd. and shows that vfd is over -heated . Some case if you change the fan which is under the sensor then the sensor will not get heated and will work propely. if this cant help then there will some sensor problem. for that contact allen-bradly

WHAT IS POWER FACTOR? HOW MUCH IT REQUIRED?

Hello everyone... Today we gonna discuss something which is very important in industrial topic. Every Electrical engineer needs to be very conscious about this. WHAT IS POWER FACTOR? HOW MUCH IT REQUIRED?😅 Now all of you know that every industry required to maintain as possible as 0.99 pf . but most of the engineers are not aware what is the required KVAR to reach or to make 0.99 pf. so here i am gonna share something which will show how to and what are the requirement. What is power factor?           "In ac circuits power factor is the ration of real power to apparent power"            "In dc circuits power factor is unity because reactive power absorbed by any inductive circuit is zero. so power factor is unity"  Now most of the of us are working with already installed plant or industries so we don't know what is KVAR rating we need to maintain our power factor at 0.99.  from google image ...
