Hello

I have a 2008 Hartford pro1000 VMC with a fanuc control

Recently when you switch it on it gets so far and then 3 alarms come up
all
401 servo alarm x axis vrdy off
same alarm for Y and Z

if you keep turning the machine on an off it comes on normally but then when you set the spindle going it will alarm out sometimes after a day or after 5 minutes

We figured it was when you switched the machine off at the back ,so we only switched the front off and it was fine for months , but now it is constant

I have had a machine electrician in and he said its point to the motor control unit A06B 6140 h015 . I had a word with someone who does exchange and he said doesnt sound like that unit

it sounds like it could be a server issue ?

Then another machine fitter said it sounds like a safety switch

does anyone on here maybe know where to start

Many thanks

Simon
