The Yaskawa SGDM-04ADA-V was sent in with alarm A.10. According to the customer the alarm appeared when main power was applied together with the Servo ON signal. During our first test this behavior was reproduced instantly. When ...
Initial Situation.
The customer sent a Yaskawa SGMG-44A2AAG motor together with the matching SGDB-30VDY1 servo amplifier. The axis triggered an overload alarm at irregular intervals. The machine frequently stopped during operation without showing a...
A long standing customer reported recurring fault messages on his older machine equipped with a MELDAS 500 control system. The machine stopped sporadically during the power up sequence or shortly after servo ON. The codes 65 rush relay error and 6C ma...
The MR-J2S-40A arrived in our workshop with the fault that the servo amplifier triggered alarm AL.24 immediately after the main circuit was energized. AL.24 is one of the decisive protective alarms in the MR-J2S series and clearly indicates a ground f...
A machine operator reported that his production process increasingly suffered from spindle failures. The spindle tried to start, produced a deep humming noise and aborted after a few seconds with alarm 31, shortly followed by 9031. The L and M axes we...
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...
