Hello, I am using a PowerFlex 700 drive for a pump jack application on a 500V not grounded power network. I want to install a regenerative unit(Revkon SVC) for this drive and i want to know what parameters i need to change. I also need to know what is the simplest way to know how much energy is...

Thank you Skogsgurra, this seems to be the problem.

Hello friends, I have a problem with a motor choke(code: VW3A5104, Schneider). It is installed on the output of a 15kW VSD(code: 6SE6400-2UE31-5DA1) on a 500V/50Hz network. The problem is that the motor choke becomes very hot when we run the pump(pump application) almost full speed(40Hz) and...

Power OFF->Power ON and try again.

Hello, The only way to access the PLC is to manually input 5 times the wrong password with the on-board display. After this you will be asked if you want to delete the program(which will remove the password too). You can find additional info in the manual of the PLC. Have a nice day.

I am not looking for a specific brand, but if you have a brand that you liked please send some links/data for their products. About the marketing material i only found something i am looking for only at ABB and Allen Bradley site.

Yes, and i found something on ABB site, see link...

Hello, Does anyone have documentation on VFD specifically for oil extraction. I heard that the difference between classic and this drives is on parameters assignment(you have an additional option for oil extraction)and i am interested in finding out more. Thank you.

Connect the motor only on star an see if it works. After that you will now what to do.

Best solution for you is to install an external brake resistor, this will allow the VFD to dissipate the energy created by the ramp down function without damage to the drive. This solution will protect the VFD when you will connect the transmmision to the load(particularly recommended when you...

Beside checking the VFD parameters also check the mechanics of the fan(bearings, propeller, alignment). An error on this side can also trigger the same symptoms.

It was just a joke on the fact that you hurry to press submit before you collect all your ideas. Sorry if i offended.

electricpete needs a star for his posts :D

Try Siemens S7-300 PLC. Siemens offers additional modules to install on the S7-300 CPU for analog signal for any requirements.

You are right is class 5 trip OL. I will install a class 10 OL to see if it works and post the conclusions.

Change to Class 20 OL looks like the best choice. Thanks rbulsara.

We have 3 phase 50Hz 380 V between 2 phase and 220V between phase and N.

I set the OL at 16 amps and still trips, only when i replaced it with a 20 amps OL than it runs OK and has the starting current of 60 amps and the running current of 13 amps clockwise and 10.2 CCW. The real problem is as compositepro said, high inertia, that is the reason why it takes so long...

rbulsara, the OL protection is set to 12 amps and the motor plate says 11.6. waross what do you mean by "230V systems and 380V systems".
