Miller tp104 /4c does not run

Hi
I have problem problems with Miller tp104 /4c, machine Nr. G21938, year 1990
The machine work inch forward and reverse
But when Bush run the machine do not run
Can anyone one help me

 

Hi sir:

Normally this motor is from D.C, like Man Roland .

1) Test the voltage feeding the electronic board for Thyristor .

2) Test the fuses.

3) If everything is o.kç the Thyristor board is defective. Look for some components defective, dry+cold joint solder.+loose connector.

 

Thanks for your reply
The machine is working good in inch
Why it doesn't work in production run

 

Please Review as indicated, the electronic Board, where the Thyristor Is there, with His electronic components.

Thyristor can be defective or associate electronic components.

Inching in DC Drives, does Not imply that Is Good, Is different matter.

Proceed with m Steps.

Blessing

 

Thanks for your reply
I will check next Monday
Because I am not near the machine

 

Thanks for your reply
