Siemens Masterdrive Repair, Servicing and Parts
We are suppliers of Siemens Micromaster – Masterdrive Sales and Repairs.
We stock AC drives and vector controllers from Siemen’s Masterdrive and Micromaster series, both new and refurbished at heavily discounted prices. We service and repair many drives that are now obsolete.
In addition we also supply many other Siemens Spare Parts.
Fans & Fuses
The two most common components to fail on a MASTERDRIVE are the cooling fan and fuses. The cooling fans eventually fail due to dust getting into the bearings of the fan. This is an easy repair that you can perform yourself if you keep a spare fan in stock. Fuses will undoubtedly fail from time to time with power fluctuations or surges. Please contact us if you need help with these or any other replacement parts.
All AC drives have large capacitors that are necessary to maintain the internal DC bus voltages. Under normal operating conditions, these capacitors have current continuously flowing through them that keep them charged. AC drives that are in storage or unpowered for periods exceeding 1-2 years begin to see these internal capacitors discharge voltage. When MASTERDRIVES have been unpowered for periods greater than 12 to 24 months, it is highly recommended to pre-charge the capacitors with a gradually-increased DC bus voltage. A drive that has been without power for more than 24 months and has not been precharged has the potential to damage its capacitors when full voltage is applied to the drive.
