Need Help - 840D with 611U Oerlikon Gear Cutting Machine
Dear All
Whenever command is given for to rotate immediately we get following errors
a) 25000 : Axis B Hardware fault of active encoder
b) 300504 : Axis B Measuring Circuit error
- We tried by interchanging control card on Siemens drives between B and Q axis
- Diagnosis – Service axis - Green LED for Measuring System 1 active is ON for B axis like other running machines
- After NCK Reset, we don’t get any error, error comes only when command is given to B for rotation
We r planning to replace Motor encoder to isolate the problem.
This axis also hs got Passive Encoder (Heidenhain Make)
Please advice
Best Regards,
M. Rishikesh
