Code 33
Software Identification. This is needed if you call SWI Customer Service.
Code 127
Measure's the backlash in the system.
Code 128
Enter backlash compensation.
Possible Cause
Check This
X and Z-axis Gibs are not adjusted
properly
Check the adjustment of the X and Z-axis Gibs using the
X and Z-axis Gib adjustment procedures. Ensure the
belts are not overtightened. Any abnormal sound from
the belts is an indication of misalignment or mis-
adjustment.
Calibration or Backlash problem
Recalibrate the machine. Reset the Backlash. Check
Repeatability and Positional Accuracy. See Calibration &
Backlash Constants section.
Binding in the Drive Train
Check Repeatability using the Repeatability and Positional
Accuracy procedure. Check the torque reading of the
Drive Train. Step by step, carefully inspect the Drive
Train for any binding. It may be necessary to
disassemble and then reassemble the Drive Train. See
Mechanical Drive Train (X, Z) Section 4.2
3.3.4 Vibration in Motion
While axis is moving there is vibration or noise coming from the X or Z-axis.
Perform the following Service Codes and procedures:
Code 127
Measure's the backlash in the system.
Code 128
Enter backlash compensation.
Possible Cause
Check This
Too much backlash entered in Code 128.
Recheck the machines backlash.
Inadequate or no Lubrication to Ballscrews
and Way surfaces
Make sure all the Way surfaces are getting proper
lubrication. If not, check to make sure that the lube pump
is functioning properly. Also check for any pinched or
blocked oil lines. See Lubrication section
X Gib is not making good contact.
Pull gibs out and mark with a blue die to check where the
gibs are making contact. It is recommended that the gibs
uniformly contact at least 80% of the surface.
Binding or looseness in the Drive Train
Check Repeatability using the Repeatability and Positional
Accuracy procedure. Check the torque reading of the
Drive Train. Step by step, carefully inspect the Drive Train
for any binding or looseness. It may be necessary to
disassemble and then reassemble the Drive Train. See
Mechanical Drive Train (X, Z) Section 4.2
Axis Motor belt too tight.
Loosen belt.
Misalignment of ball screw
See Mechanical Drive Train (X, Z) Section 4.2
