Basic Troubleshooting
Troubleshooting is the logical elimination of all necessary steps in a pro-
cess or the potential variables within a step until the “Fault” is uncovered.
1. When a fault arises, gather as much information as possible about the
events leading up to the fault. This often eliminates many steps in the
troubleshooting process.
2. Determine where the fault resides. “Is this a Machine or CNC fault?”
3. Begin with the basic question of whether power exists. If power does
not exist, ask the following questions:
-
Is there power at the source? – Check power at the source.
-
Is there power to the machine? –Check power at the main discon-
nect on the machine, refer to the schematics.
-
Is there power to the control? – Check the CNC Maintenance Man-
ual for details, see
4. After confirming that power exists and the control and machine are
“On,” ask:
-
Is the machine
READY
? – See
-
Is the control
READY
.
Continuing in this manner should lead to the source of the Fault.
If in doubt, it is always safe to start at the beginning. The flow chart, in
, will prove helpful in beginning the troubleshooting process.
If the machine and control are both READY and an alarm is generated,
finding the cause of the fault is greatly simplified:
1. Determine if the alarm is a CNC alarm or a Machine alarm.
2. Look up the proper alarm listing in
If no alarm is displayed use the other available troubleshooting tools dis-
cussed in
Notes for Figure 5-1
1. Machine and CNC alarms are listed in
of this Maintenance Guide.
2. Refer to the CNC Maintenance Manual for more detail on CNC alarms.
