Dear Friends,
We have a Mitsubishi Horizontal Machining Center with the following Spex;
X-Axis = 1500mm 23Nm/18A DC Fanuc Servo Motor. Inductosyne Scale Feedback
Y-Axis = 1000mm 23Nm/18A DC Fanuc Servo Motor Inductosyne Scale Feedback
Z-Axis = 900mm 37Nm/24A DC Fanuc Servo Motor Inductosyne Scale Feedback
B-Axis = 1x360 Deg Fanuc DC Servo Motor. Rotary Encoder Feedback
Spindle Motor is a Fanuc AC servo 11/15Kw.
CNC Controller = Fanuc 6M - B.
Originally the Machine came with a 15/18Kw Mitsubishi DC Motor with a Diarol/Mitsubishi Drive. We had some issues with this and around two years back replaced to a Fanuc 11/15 Kw AC Spindle servo Motor with a Fanuc Drive.
This system worked very well.
Now there is some problem with the I/O cards and machine is not getting into "READY" status.
The problem started with the machine tripping after 2/3 Minutes of switching 'ON', we had few of our regular repair people looking at it, they took the I/O cards for repair, nothing worked, not they say replace the complete system.
Please advice.
On The Fanuc side there is no trouble. The Axis motors & Controller are all in fine shape.
Issue is with the I/O cards
The repair chap bypassed few preconditions to get the machine into "READY" Status, however the 'M' Codes do not work.
Now in the present situation, what can we do best.
If you need more information, it can be provided.
Please advice
Thank you all in advance.
