should i follow the steps

 

Yes, check the signal of brake switch...

 

Dear james,
Is it new installation?

 

yes 4 - 5 months
I checked the switch, it works normally but the problem is not solved

 

1. check the motor encoder/tacho
2. is there any error with the main drive unit?

 

The switch works, ....the input says the same?

 

Hi
We have the same problem with UWR but only when i start from delivery side.

When i start from feeder side its all ok.
I have checked the Brake switch - all ok.
How can i solve this problem?
Thanks

 

I still could not solve the problem, especially after the machine warms up.

 

please let me know if you solve the problem

 

What error there is maindrive

 

There is error 08 at the Simoreg

 

hello
08: not ready for operation, i.e. terminal 19 =“0“ (EMERGENCY OFF is activated)
probably the input board at delivery station is defective. you must check slot 3,4 (input boards) and slot 2 (safety relay board UWR)

 

Thanks.
But I have done those checking. (no results)
I'll try to change the Tachogenerator.
This is something I haven't done before

 

you said if you start from the feeder panel it's all ok and only have a problem from the delivery side. then it's not the tachogenerator I think you should check the delivery station again.

 

Did you get the solution

 

When the problem is present only at one station panel control then is a problem with station safety bus, or maybe is just the board where the run commands are mounted this is easy to check just interchange the control panel board with other station

 

safety relay board slot 2 in the delivery station and the board where the run commands are mounted.

 

I tried to change all the boards with other station. But I didn't get the result (((((
May be the cable ?
