arthr Posts: 23 Rating: (0)	I have a problem with a drive model 6SE7035 - 1EK60 wires are magnetized when I start the drive and displays on the PMU "0000", I check the current in the motor and the drive monitor show 450 Amp, I swap all the components and the same problem occurs. when I start the drive motor turns slowly and wires magnetize and repel each other and displays on the PMU "0000", I send you the DNL file with all the parameter used to run the motor andwhich causes this error. I'm controlling a motor of 300 HP with this drive. somebody who can help me for this error. Regardings.

arthr Posts: 23 Rating: (0)	i check all the signs and all are well. the problems is when i send the signal to move the motor, the current increase at 450 A y the wire begin to repel each other. i think is some parameter.

For this, set P443 to 58 and start the drive then increase or decrease speed with PMU up and down arrow key Please check all these and revert with results Also tell us – what is the control mode you are using (P100-??) Regards, Devesh Vithani

If it is commissioning job, always best to run the motor uncoupled and from PMU. Regards, Vijay

arthr Posts: 23 Rating: (0)	These two drives are mounted on a crane buckets, Opening or closing them or up and down the buckets., the drive's close is the master and the slave hold. this problem started when braking resistors damage. The hold`drive is in closed loop with P100 = 4, but to rule out the encoder open loop pass it with P100 = 3 ,and the problem persists. Attachment SAM_0192.JPG (644 Downloads)

Ok but check r014 after giving start command and just share us the readings you get - you will find us here on monday also

arthr Posts: 23 Rating: (0)	dear Vithani I remember that i wanted to solve the problem performing the drive with autotuning, can you guide me how to make the autoning , i tried to perfroming the autotuning but i can realize it, because even though I put the key P358.1 = 414 y P358.2=262 y and the lock P359.1=414 y P359.2=262 did not allow me do it. On the Drive Monitor appear a windows that say I have not sufficient privileges to perform it. Than anything else I need to do the auto tuning? Question? when I add some new component to the system inverter-motor ,does i have to make auto tuning, ? Can this cause the behavior of magnetized wire? Regards Vithani

Regards Vithani Well, I suggest you to go step by step. Before checking other possibilities, you should check the one which most suspicious Anyways, have you changed P60 after puting key in P358? First change P60 to 7 - and check whether you got full access or not And for autotunning, you need to change P60 to 5 and thenonly you can changeP115 to 4 and 5 If you have changed drive component- you dont need to perform autotunning, if you have changed something in field, autotunning is required But i am not sure this can help you much because autotunning is for fine response from drive but in your case motor is not even getting started for rotating Moreover if you are not getting any fault after starting, i am mostly sure that drive is not getting speed setpoint Regards, Devesh Vithani

arthr Posts: 23 Rating: (0)	To: Vithani OK i will go step by step. Im not change any component in the drive, i just changed one DBU(Dynamic Brake Unit) this unit was burnedin a short circuit occurred in the resistance, therefore i remplaced the DBU and the resitor. well i´ll do it all the test you suggest to me thanks you Regards Vithani.

arthr Posts: 23 Rating: (0)	Dear: Vithani I have in parameter P443.1 a reading 507 i changed the parameter P443 to 58 and i start the drive and nothing happened. You suggested that when i do this, i could control the drive with PMU up and down arrow key, but nothing happened. what else i need to set in the parameters to might control the drive with PMU? I already checked the speed reference in the control terminal strip X-102 (terminals 15+ , 16 -) and give me 0~10 VCC, all this in the CUVC. With this I´m sure that reference´s signal is Ok.. What other test can you suggest to do, and might solve the problem. if you need some pictures or files about the programation of drive i can send you.
