Newport MM 1000 dc Motion controller drive Problems
One day, during I was operating the Newport MM 1000 dc Motion
controller drive with delay stepper line, strange characters (????) appeared on the front panel. Then when I turned off and on again, many kind of messages were shown. "??????", "Check 5V", etc. Or it stopped while it was initializing parameters. When I asked the Newport, it is too old model so they cannot solve it. But they suspected internal power supply problem or PCB problem. What would be problem? How would I fix it? Please help me. (I have replced 4 amp-250V Slo Blo fuse on it, but there was still the problem.) |
