Dear james,
Is it new installation?

 

[James07]

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

 

[Asim Shehzad]

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

 

[drukman]

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

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?

[James07]

[James07]

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)

 

[AndrewUA]

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

 

[Asim Shehzad]

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.

 

[Rohit kutlehria]

Did you get the solution

 

[sergios68]

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

 

[Asim Shehzad]

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

 

[AndrewUA]

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