Mitsubishi MDS-D-V3-202020 servo drive: “The machine is running perfectly again”
“The machine is running perfectly again, and I am very satisfied with the solution.”
Translated excerpt from written customer feedback. The customer is a manufacturing business in East Westphalia, Germany, producing lubrication equipment and turned parts. Three axes had failed on its Citizen L7-20. The affected Mitsubishi servo drive was an MDS-D-V3-202020, also marked MDSDV3-202020 on the nameplate.
From inspection to a replacement solution
Inspection of the submitted servo drive revealed a defective control board. The initial repair attempt did not achieve the required result. We therefore agreed the next steps with the customer and sourced a replacement unit.
We overhauled and tested the replacement before shipment. A prepared replacement unit provided the solution for this order.
Support during commissioning
Our support continued after shipment. We also assisted the customer with troubleshooting during commissioning. In his subsequent message, he confirmed that the machine was running perfectly again and that he was very satisfied with the solution.
Customer feedback
“Thank you very much for your competent and professional support.”
This feedback recognises the support provided through to a functioning machine. Thank you for your trust, cooperation and kind feedback. We are pleased that the Citizen is working properly again.
