Thanks for clarification on those terms!

I was thinking that this is called a "servo amplifier" or "servo driver", whereas the mechanical part being called the "servo" or "servo motor". So I was...

Yes, that's what I already thought. This forum here is more general, often only scratching the surface when it comes to *real* faults.

Thanks also for sharing the link to the other...

The problem is with the BDS4 of the Z-axis.

In fact we just swapped servos of X and Z axis. Now the low torque Z-axis servo has a high torque with the X-Axis driver (BDS4) and vice versa, the...

This BDS4 servo driver (Kollmorgen / Cininatti Milacron) has low torque. I am 100% confident it is not the servo itself (swapped).

At rest (idle state) the servo already has low torque so I am...

We have just taken out the Z-axis servo. It DOES move with the Z-axis BDS4 now, but has very low torque.

At machine idle, servo powered up, you can relatively easily turn it by hand. When its...

Dear all,

I am investigating this issue for quite some time now on a Cincinatti Milacron Arrow 750.

The Z-axis is not moving with the Z-axis BDS4 servo amplifier ("driver").

However, Z-axis...

I managed to get the electrical wiring diagrams for the machine. Thanks for your advice!

As for the BIOS settings of the WS board, I think they might not be too critical, but I will have a look at...

Thanks! Do you know of anyone here in Germany who could help me with schematics?

About the batteries, you are right. The WS board battery would need replacement but is located inside the DALLAS...

Since several days now I am troubleshooting a Cincinnati Milacron Arrow 750 with Vickers Acramatic 2100 (A2100) control software. The machine (built 1995) has several issues as it was sitting unused...
