SM52-2p - Error S-BLT CON

Dear colleagues. We got error on our SM52-2p press.
Init test: S-BLT CON: BFDD
Dyn test: S-BLT CON: 7FDF

Could you advise what does it mean?
Thank you in advance.

 

Init test

1)Power part test cannot to carried out,condition for testing not fulfilled (in most cases supply voltage). Press does not start running.
2)câble connection to rotor position encoder interrupted.

Dyn test

Rotor position encoder defective (identical signals from all sensor lines, wrong logic)

 

Hi sir:

for Init S-BLT CON : BFDD:

Check:
Connection cable for encoder stopped rotor position .

Dyn: S-BLT-CON: 7FDF
Check:
Position encoder faulty rotor ( identical signals from all sensor lines )

 

Thank you every body for answer. It helped Me alot.
My solution is: I have dismounted encoder of main motor. Cleaned it and connector from oil. Everything works well now.

 

Great, Good job
