Powerflex 525 drive controlled via logix5573

[danaus]

Hello, I recently replaced a power flex 525 drive which has identical parameters and is controlled via a logix 5573 controller.

I have run into a snag being the drive running the motor is going the wrong direction which is hooked up to a pump.

I have swapped phases around and the motor still continues to run the wrong direction.

Is there a parameter in the drive I can change or does this need to be done via the plc?

I have an engineer who is going to login and change if possible via the plc but if we can't eliminate it via the touch pad that would be a better solution.

Is it controlled over Ethernet also.

Thanks

Welcome!


Did you try swapping two of the motor leads [U/T1, V/T2, W/T3]? PDF page 9


Then maybe look at PDF page 17 Reverse.

Yeah tried swapping them is the plc stopping it from changing

 

[danaus]

very frustrating

I am not a electrician by trade, but if your pump is going in one direction and you swap 2 of the leads and it is still going in the same direction, I would start by polling the cover of the motor and double tjek that this is facts.

I can't see how this i possible.

If the drive always says FWD on the front and you swap only 2 phases to the motor, then it will run in the opposite direction.

Don't take offence, but you are only swapping 2 of the phases and to the motor and not the drive?

Are you looking at the right motor?

 

[danaus]

Yes I am looking at the right motor, How do I get the fwd to display Rev

Swapped blue and white around at the motor terminal block

Did you have a chance look through the linked PDF?

There is a parameter reverse disable. I think parameter number 544.

 

[danaus]

Tried the reverss key it is locked out due to being controlled via plc, paramter 544 doesn't change anything tried that already.

 

[bornwild]

can you inhibit the drive and change the parameter. Is the drive in Stop mode?
There is also a chance that is disabled from the plc logic

 

[Bob O]

And you swapped two leads to the motor/load side and rotation didn't change?

 

[danaus]

Its just in ready state.

 

[bornwild]

Can you go in the drive properties in the plc program and change it from there. What does the parameter A 544 read .??
if it is 0 means reverse enabled
If it is 1 means reverse disabled

Will get the engineer to have a look tomorrow and see what we come up. thanks everyone
