Common Failures: E/R module failure


A common failure on Siemens and Heidenhain Controlled CNC machines such as XYZ, Hardinge, Bridgeport, Breton and 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 a 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.

Today I installed this fantastic used Dugard ECO 1000 VMC with Siemens 828D Control and Sinamics drives.

It is a great machine with a brilliant control. Even though it’s 9 years old, it looks almost new.

The X axis was immediately tripping out on this 1998 Bridgeport VMC800 when trying to reference it. We were called in as the customer suspected the faults were caused by a faulty servo drive or servo motor.

The motor passed the insulation and balance tests and the servo drive passed the diode check, so we had to dig deeper.


A family business established in 2016, Control CNC Services Ltd. has over 30 years of experience in the CNC machine tool industry. 

Our engineers support all aspects of CNC applications. We provide a total breakdown solutions package; whether the fault is mechanical, electrical, electronic, software, control, or drive, our multi-disciplined engineers will resolve the problem.
