Yaskawa SGDH-50AE Servopack: Customer feedback after repair
“The units have now been reinstalled and are working perfectly.”
The customer is a CNC machine diagnostics service provider based in North Rhine-Westphalia, Germany.
We received this feedback in response to our follow-up enquiry about reinstallation after repairing a Yaskawa SGDH-50AE Servopack, version 3353B. The quotation is translated from the customer’s German reply.
Technical background
The Servopack showed no signs of operation during our initial inspection. After repairing the internal power supply, the unit could be switched on again. Further faults then became apparent, including Alarm 10. The power stage also required repair. We subsequently carried out a complete preventive overhaul of the unit.
Repair video and photographs
The original footage and photographs document the unit and a test run at industrypart during the repair process. They do not show subsequent operation at the customer’s premises.
