Hello all,

we have a CNC Lathe (1986, Hitachi seiki, Hitec Turn, Yasnac Control) And it gave us several alarms as below:

Alarm# Descriptions
392 TG ERROR (Z)
391 TG ERROR (X)
352 OL (Z)
351 OL (X)
310 Serval Off

Message AL-3 Thermal EXEZP SP. MOTER


Would someone have any idea how to fix these problems?

Your helps is greatly appreciated.
