One of our long-term customers commissioned us to fully overhaul an entire CNC machine – including all servo motors, spindle motors, and drive units. The machine was still functional, but the customer wanted to ensure long-term sustainability and re...
We received two units of the MR-J2-20A that intermittently displayed the E9 alarm (ABS Servo On Warning).
This kind of sporadic error is challenging, as it does not appear consistently and is often triggered by unstable signals or component degrada...
Repair Story.
The unit was delivered in a heavily contaminated condition. Already during the first inspection it became clear that the fan was completely blocked. Due to the accumulated dirt, it could no longer rotate mechanically.
A detailed an...
In the world of automation and CNC technology, Yaskawa SGDV Servopacks are known for their precision and reliability. But behind the seemingly simple model designation SGDV-120AE1A often lies hidden complexity, namely, the version number. And this ver...
The customer reported that the machine stopped after a few minutes, showing error “8” on the display of the Power Supply Unit. This alarm indicates that the internal software process of the PSU did not complete within the required time frame. As a...
The Yaskawa SGDM-10DN Servopack was sent in with the following issue:The A-axis was supposed to move to its reference point, but the machine monitor showed a deviation of 7°, even though the axis did not move at all.Shortly after, the error A-axis ti...
A customer reported a failure with Alarm 1 (Power Supply Error). The CNC machine could no longer operate, production was stopped. Mitsubishi offered an exchange unit, but the cost was very high. Since the customer had already entrusted us with several...
A customer contacted us after experiencing repeated Alarm 3B Power module overheat on their Mitsubishi MDS-B-SP-110 spindle drive. At first, the error appeared only sporadically and could be cleared by restarting the machine. But within a few weeks, ...
The Okuma MIV08-3-V5 Spindle Drive arrived with a sporadic Alarm 04. In the machine, the error mainly occurred during rapid acceleration, sometimes only after extended operation. Such intermittent faults usually indicate borderline insulation paths, c...
In many production environments, the Yaskawa SGMSH-20DCA6F-OY motor is a reliable workhorse. Yet one particular weak spot emerges frequently in our repair work: the encoder.A typical scenario begins with the drive often an SGDH-20DE – showing a...
