MM4006 8 -Axis Motion Controller/Driver
E Troubleshooting Guide
Remember that there are no user-serviceable parts or adjustments to be
made inside the controller or any other component. Contact Newport for
any repair or other hardware corrective action.
Most of the time, a blown fuse or an error reported by the controller is the
result of a more serious problem. Fixing the problem should include not
only correcting the effect (blown fuse, limit switch. etc.) but also the cause
of the failure. Analyze the problem carefully to avoid repeating it in the
future. The following is a list of the most probable problems and their cor-
rective actions. Use it as a reference but keep in mind that in most cases a
perceived error is usually an operator error or has a simple solution.
