Description
Fuji servo drive repair
Model: RYC202C3
Failure phenomenon: the use of a sudden no show
Fault analysis: description of open circuit board according to the fault inspection provided by the customer, the key power driver board power supply and fan Ming found no traces of burned out. But the circuit board copper corrosion. Some estimation of the servo used in harsh environment, electricity detection 5V output only 0.6V, check the feedback circuit without switch is also no problem problem. The regulator has been damaged. But found in boot failure still. Because of the power supply for the multi output. Other groups have suspected load short circuit. Then disconnect all load. The fault still. Finally concluded as the switch transformer. The transformer coil welding, dismantle, found the innermost layer, the primary windings are short-circuit due. A primary short circuit, destroyed the oscillation conditions, therefore, the output voltage of 5V is very low. Re winding transformer for fault.
Repair: replace the power regulator, switching transformer winding.
Fuji server maintenance common failures: no show, lack of phase, over current, over voltage, under voltage, overheating, overload, grounding, parameter errors, there is no output can be maintained.
