ProTURN SLX 1630 ProtoTRAK SLX CNC Safety, Installation, Service & Parts List Manual
Code 33
Software Identification. This is needed if you call Customer Service.
Code 12
Feed Forward Constant
Code 127
Measure's the backlash in the system
Code 128
Enter backlash compensation
Code 100
Axis open loop test.
Used to check the maximum feedrate of an axis
and if the encoders are counting
Possible Cause
Check This
X-axis Gib are not adjusted
properly
Check the adjustment of the X-axis Gib using the X-axis Gib
adjustment procedures, See Section 5.2.1..
Calibration or Backlash problem
Recalibrate the machine. Reset the Backlash. Check
Repeatability and Positional Accuracy. See Calibration &
Backlash Constants section 5.2.2.
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.
3.2.5 Vibration in Motion
While axis is moving there is vibration or noise coming from the X or Z-axis.
Do the following Service Codes and procedures:
Code 12
Feed Forward Constant
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. See Section 5.2.2.
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 2.13.
X Gib 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. See Section
5.2.1 Crosslide gib adjustment.
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.
3.2.6 Searching Axis
The ballscrews are slowly turning back and forth when the servos are engaged.
Do the following Service Code and procedures:
Code 12
Sets a feed forward power constant to drive axis motors.
Code 128
Backlash compensation on single feedback machines.
