Description

Troubleshooting (Cont)
General (Cont)
NEVER start off by wildly replacing boards or units, this
can result in the destruction of good boards in the
system. Try to narrow a problem down to a single
component causing a problem.
PROBLEM ISOLATION:
When troubleshooting the system a problem can be
isolated by indications of operation that determine the
type of problem that is occurring.
These indications are:
Control has power. This is most easily noticed by
looking for LEDs on the computer boards and
display on the teach pendant when the disconnect
is turned on. If a problem exists here, check circuit
diagrams and trace incoming power to the power
supply and the power supply voltages. Refer to the
Power ON chapter in this manual.
Computer is operating. This is noticed by checking for
the welcome display on the teach pendant and
checking for the “EN” LED on the system board. If
a problem exists here, check error code or check
for LED indications in the next section of this
chapter.
Motors ON. This is found by pulling the enable device
to the center position and observing the Motors ON
light. If a problem exists here, check the system
board’s LED’s to see if the run chains are OK. Then
check the circuit diagrams for problems. Refer to
the Motors On chapter of this manual.
Robot moves. This is checked by use of the joystick to
move each axis individually. If an axis movement
causes a fault, then troubleshoot the problem for
that axis. Refer to the Motors & Resolvers chapter
of this manual.
Robot runs program. Start the normal program
execution. If the program has a problem then the
problem is possibly an interfacing problem. Refer
to the I/O chapter in this manual.
