Common Failures - E/R module failure

Posted on 23rd July 2020

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!

Replacement E/R Module

We keep a large stock of these units and can offer them on service exchange basis. Please contact us for further details.

Siemens hardware and software is what we specialise in, from diagnosis to cure speak to us with any faults on Siemens Controls and Drives.
