Hi sir:
See if the main switch Q2A28, has relais thermic, and adjust the Pot a little higher in Amps,
since this is most sensitive, can be a reaso for to Stop the machine while is running.
2) The electronic board with the Thyristor look for loose wires, dirty contact, or corroded contacts in the wires-connectors.
3) look if the voltage Vdc in the armature- of motor is o.k , otherwise measure the input of electronic board for 380Vaca or 415 or whatever voltages that you are using.
4) Finally see if the electronic board has dry+colder joints solder.
