A long-standing industrial customer faced an important decision. The machine tool he had relied on for more than fifteen years was showing increasing signs of aging. More and more often, the CNC reported axis and servo faults; sometimes the errors dis...
Challenge at Our Customer in Greece.
Approximately two years ago we began working intensively on the Tamagawa encoder series OAER5K-1X-3-8-108. The trigger was a major industrial customer from Greece whose machines were repeatedly shutting down bec...
The motor was sent to us because it repeatedly failed during machining and the MDS-DH-V1-80 displayed overload alarms. The customer described that the machine sometimes ran normally for hours, but during demanding programs or increased cutting volumes...
Initial Situation and Error Description.
The Mitsubishi MR-J3-10B was sent in with error 32 Overcurrent. According to the customer, the drive occasionally shut down during fast axis movements and dynamic acceleration profiles. These conditions typi...
Initial Situation at the Customer Site
The Yaskawa CIMR-MRXN2011 converter from a STAR Micronics CNC machine was sent to us after the operator experienced increasingly unstable machine startups. The machine showed a very specific pattern: on the fi...
Repair of a Yaskawa SGMGH-05ACA2C with encoder malfunction, full diagnosis, overhaul and load test.
The motor was sent to us because it repeatedly caused faults at certain rotational speeds, especially above 1000 rpm, and the servo amplifier report...
Initial Situation.
The Yaskawa SGMKS-20A5A-MU11 was removed from a machining center using a Siemens–Yaskawa hybrid control system. The customer initially observed a motor short circuit, followed by encoder faults. The drive repeatedly shut down d...
Initial situation
The delivered Yaskawa AC servo motor SGMDH-32A2A-YR33 showed sporadic encoder errors for an extended period. The customer had previously purchased a supposedly matching UTSAE-B17BB encoder and installed it himself. After installat...
When the Fanuc A06B-6117-H303 Servo Drive Unit arrived at our workshop, the error was already clear: The machine shut down immediately after servo power-up, accompanied by the alarm “DC Bus Overcurrent”. The customer reported that the machine stop...
Initial Situation and Error Pattern
The Omron AC servo motor R7M-A10030-BS1 was sent in by the customer because the axis had become unreliable during production and repeatedly stopped without warning. The corresponding servo drive R7D-AP01H Ver.22 ...
