Possible Cause Check This
Improper Boot-up
Shut down the system and wait 10 seconds before rebooting
E-Stop is pressed in Check E-Stop. Especially if both axes will not jog
Servo Drive failure Especially, if only one axis will not jog;
See Servo Driver Section 4.5
Shorted motor See Motor Section 4.4
Poor cable or wiring connections See Electrical Connection Section 2.12
Computer/Pendant failed
See Computer/Pendant diagnostics Section 4.3
3.2.4 Axis Motor Motion Is Not Smooth
While under motor power, the motion is not smooth. The motion appears to be "rough" or jerky”.
Do the following Service Codes and procedures:
• Code 33 Software Identification. This is needed if you call SWI Customer Service.
• Code 11 Measure's the backlash in the system. Only used on machines with Dual
Feedback systems.
• Code 12 Feed Forward Constant. High feed forward constants will cause an
unstable servo system.
• Code 127 Measure's the backlash in the system. Only used on machines with single
feedback. Also used on SMX3 Z axis.
• Code 128 Enter backlash compensation. Also used on SMX3 Z axis.
•
• 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 and Y Gibs are not adjusted properly
Check the adjustment of the X and Y Gibs using the X
and Y Gib adjustment procedures.
TRAK Sensor or Glass Scale problem
Make sure that the Sensor or Glass Scale is installed
correctly according to the Sensor or Glass Scale
Installation procedures. Check for any loose brackets or
misalignment etc. Also, check to make sure the Sensor or
Glass Scale assemblies are functioning correctly. See
TRAK Sensors or Glass Scales Section 4.6 & 4.7
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, Y) Section 4.2
3.2.5 Vibration in Motion
While axis is moving there is vibration or noise coming from the X or Y-axis.
Do the following Service Codes and procedures:
