A common failure on Siemens and Heidenhain Controlled CNC machines such as XYZ, Hardinge, Bridgeport, Breton, Dugard is E/R module failure.
Over time the internal fans stop working and coolant and contaminant ingress occurs. The most common failure type we see is the 16/21 KW (6SN1145-1BA01-0BA1(2/0).
These units are responsible for powering up the entire drive and NC system so when they fail, it means your machine isn’t producing!
We keep a large stock of these units and can offer them on service exchange basis. Please contact us for further details.
