4-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.
Problem
Stand-By red LED
does not come on
Cause
Corrective Action
Rear power
switch turned
off
Turn on the main power switch
located on the power entry mod-
ule in the rear of the unit.
A physically pre-
sent axis is
declared uncon-
nected
Bad connection
Turn power off and verify the
motion device cable connection.
Bad component
Turn power off and swap motor
cable with another axis (if cables
are identical) to locate the prob-
lem. Contact Newport for cable
replacement or motion device
service.
Unplugged
power cord
Plug the power cord in the
appropriate outlet. Observe all
caution notes and procedures
described in the System Setup
section.
Blown fuse
Replace the line fuse as
described in the System Setup
section. Beware that the fuse
blows only when a serious prob-
lem arises. If fuse blows again,
contact Newport for service.
No electrical
power
Verify with an adequate tester or
another electrical device (lamp,
etc.) that the power is present in
the outlet. If not, contact an elec-
trician to correct the problem.
