Fanuc AC servo drives, dual or triples Fanuc 11, Fanuc 15, Fanuc 0 smoke, OC alarm, blown fuses, expensive to repair    
GE HiAk servo drives GE-1050 or Bendix 5, Fanuc 6 blows fuses, red led is lit often the control board and power supply are contributing to the problem PWM-5  
GE HiAk servo drives module style only GE-2000 frequent module failure, also smokes control board, very expensive to repair    
GE AC-200 servo drives only GE-2000 smoke, green Leds are not correct, does not like high line voltage    
Hurco servo drives Hurco smoke, OC alarm CACR-SR10  
Mitsubishi DC servo drives Mitsubishi Leds wrong, OC alarm, blown fuse

smoke, OC alarms, cannot be repaired if arcing damage on top board

 BLD-50, BLD30, BLD-75, BLD2-50  
Okuma BDU series drives Okuma OSP 5000 LED alarm, make sure dip switches are correct. Very reliable. Always repairable. BDU-30, BDU-50, BDU-75  
Siemens DC servo drives Siemens, Fanuc 6, Index smoke, blown fuse we upgrade this unit  
Warner & Swasey DC servo drives Bendix 5, GE 1050 Trip circuit breaker, axis vibrates    
Yaskawa DC servo drives Yasnac red led CPCR-MR  
Yaskawa AC servo drives Yasnac OC alarm, top board failure is common CACR-SR10, CPQR  

 

The primary causes of failure of spindle drives is fan failure, running hot and cast iron dust grime. Keep your electrical cabinets closed, keep your fans in good repair and KEEP YOUR CABINET FILTERS CLEAN!.

When troubleshooting any AC or DC PWM servo drive, it is risky to swap top boards while trying to find the problem. A bad top board can blow the power modules and bad power modules usually blow the top board. Board swapping often leads to 2 MACHINES DOWN! Call the OEM and obtain their procedure for checking the power modules with a ohmmeter. Then check the for the correct base drive voltages on the top board without DC bus voltage. We provide phone troubleshooting for the above drives on a pay basis.
