Introduction as a Real Service Case.
A machine manufacturer from the precision machining industry reported a sudden production stoppage on a CNC machining system equipped with a Mitsubishi MDS drive system. The machine stopped abruptly during activ...
A customer from the machine tool industry reported repeated production failures on an axis equipped with a Mitsubishi AC servo system consisting of a MR-J2S-350B servo amplifier and an HC-SFS352 servo motor. After approximately 20 minutes of operation...
An industrial customer reported the nearly simultaneous failure of two identical Mitsubishi Servo Drive Units type Mitsubishi MDS-B-V24-0505 from two different machines. Both systems suddenly stopped operating without warning. The affected CNC machine...
An unexpected machine shutdown in a Traub CNC lathe led to the shipment of a Mitsubishi MDS-A-SP-220 spindle drive unit for technical analysis. The operator reported recurring failures during longer machining cycles. The machine reproducibly stopped w...
Introduction as a Real Service Case.
A Haas milling machine experienced a complete spindle failure during machining. The spindle would no longer accelerate, the machining process stopped, and the machine displayed the message “Spindle Drive Fail�...
A defective servo drive system in an industrial production machine caused recurring communication errors between a Yaskawa SGMPH-08A1A-SE31 servo motor and the connected SGDK-101010AEA-V servopack. The machine experienced multiple unplanned stoppages,...
A Yaskawa SGDB-10ANY11 Servopack was sent to our workshop from an active CNC production line after one axis suddenly stopped during operation. The machine operator reported a recurring A.10 alarm immediately after servo activation. The affected machin...
Introduction as a Real Service Case.
A Mitsubishi MDS-B-V14-35 Servo Drive Unit arrived from a CNC production facility because the machine repeatedly stopped with intermittent Alarm 32. The fault did not occur continuously, but sporadically under l...
This case involves a Yaskawa SGMGH-09ACA6S operating together with a Yaskawa SGDH-10AE. The machine repeatedly reported alarm A.10, while the servo drive showed continuous thermal overload behavior.
The fault was not immediately reproducible. It ap...
The unit in question, a Mitsubishi MDS-DM-V3-202020 servo drive unit, was received with Alarm 32. According to the fault description, the alarm occurred during machine operation and caused an immediate stop of the axis. Alarm 32 in this series indicat...
