Hi,
We are putting a rebuilt spindle back in an Hitachi Seiki VM40III with a lambda 10 control. And we get this alarm on power up:

2AB7 VDE No Feed Condition Incomplete


We can move the axis manually

The machine will not home.

We can not clear the alarm.

We do not know what the alarm is about.

Any help would be appriciated.

Regards,

Philip
