Near the current limit come F60010 approx once a day

Hello!

Drive:  6RA80 850A 4Q 400V

Motor: 630A 330V

near the current limit (>90% of motor current limit) come F60010 approx once a day. Its mean. Fuse blown but fuses are correct and after the acknoledge run it correctly. How can we or solve the problem? Can to send anybody any description of this problem.

Thanks

Split from SINAMICS DCM WITH F60010.

hej,

F60010 does not exactly say "Fuse blown", actually it says: "Armature circuit uneven current Distribution".

The F60010 Error-Message also delievers also some Parameters for Fault analysis.

According to List Manual:
r50047[1]: Average current value through all armature thyristors.
r50047[2]: Average current value through the thyristor with the excessively low current, in torque direction I.
r50047[3]: Average current value through the thyristor with the excessively low current, in torque direction II.

If there is a SD-Card in your DCM, you could save some internal Error-Data on it. Please refer to:

10.33.1  Diagnostic memory from operating instructions: https://support.industry.siemens.com/cs/de/en/view/109478240

after that you can send this data to siemens Support.

 Hello,

Please check the value in r0949 which will be help to analyse the problem.

Dear Evereybody!

Actually decrease the Fault to once a week. Usually when starts the motor.

Error code: F60010

r50047.0  - 15.000

r50047.1 - 0.208 (usually approx but not equal +0.0)

r50047.2 - 0.068 (usually approx but not equal +0.0)

r50047.3-30 - equal 0.0

r50047.31 - 60010.000

I don't know why?

Have you got any idea? We have not SD card in drive.

Hello,

F60010 signifies - Armature current is uneven.

1. If average current value across all thyristors is > 20% of device rated current or

2.  Current in thyristors is significantly low for a period of 1 sec, if the value is < 35% of the average value across all thyristors.

In your case since it is 30% in toruqe II direction, drive is tripping on F60010. 

Please reply following points.

p50830 = ?

Please provide drive complete MLFB number & motor nameplate details.

Please tell me what is MLFB nuber.

Hello.

MLFB is complete order number, e.g. 6RA8087-6DV62-0AA0.

It is like 6RA80XX-XXXX
