Initial situation and fault pattern.
In this case, the unit involved was a Yaskawa SERVOPACK SGD7S-R90A20A. The device came to us with alarm A.EC8. According to the customer, the fault could still be acknowledged at first. The drive then ran again,...
The failure of a servo amplifier in industrial production often occurs without any prior warning. While some systems initially exhibit sporadic faults or communication errors, other cases result in a complete loss of functionality. This was exactly th...
Unexpected production downtime often results in high costs, delayed deliveries and significant interruptions in manufacturing. This was exactly the situation one of our industrial customers faced when their CNC machine repeatedly stopped during operat...
An Okuma MIV0102-1-B1 Servo Drive Unit was sent to our workshop with an unstable fault condition. During the initial inspection it became clear that alarm AL.03 appeared only sporadically. On the customer machine this resulted in irregular axis shutdo...
An Okuma VACIV-D6 spindle drive arrived at our workshop with a fault that was difficult to isolate: Alarm 10 appeared occasionally during machine operation. After restarting, the CNC machine could sometimes be operated again, but the fault returned wi...
Industrial Service Case.
An industrial customer contacted our repair workshop after a CNC machine repeatedly reported sporadic axis faults. The machine was equipped with a Mitsubishi AC Servo Motor HF104S-A48 operating together with a Mitsubishi MD...
An Unexpected Machine Shutdown During Spindle Operation
An industrial customer contacted our repair facility after a recurring and difficult-to-diagnose fault appeared on a CNC machine. The machine powered up normally and initially operated without...
A Small Power Supply with a Major ImpactA machine shutdown is not always caused by a servo drive or frequency inverter. In many cases, what appears to be a simple component can bring an entire production process to a standstill. That was exactly the c...
Unexpected Spindle Failure in Production.
A few weeks ago, we received a Fanuc A06B-6154-H011#H590 αiSP 11HV Spindle Drive Unit for inspection. The customer reported a complete machine stoppage because the spindle control was no longer operational...
A few weeks ago, we received a Yaskawa SGMPH-08AAA-SE41 AC Servo Motor from a Star Swiss-type lathe for inspection and repair. The motor was operating together with a Yaskawa SGDK-101010AEA-VY24 Servopack in a machine equipped with Siemens and Yaskawa...
