3.2.2 Slow Down Axis
The axis slows down and moves at a feedrate that is lower than rapid or than the
programmed feedrate.
Do the following Service Codes:
Code 33
Software Identification. This is needed if you call Customer Service.
Code 100
Axis open loop test.
Used to check the maximum feedrate of an axis
and if the encoders are counting.
Code 129
Set's the maximum allowable arc accuracy error. This applies to arcs only.
Possible Cause
Check This
The maximum allowable Arc Accuracy is
set too low.
This value will only slow down the machine during arc moves.
The factory default is set at 0.13 mm. Perform Code 129 to
check or change this value. See Service Codes Section 4.8.
Values lower than 0.13 mm may reduce the feedrate even
more.
Incoming AC voltage is inadequate
Perform Code 100. See Service Codes Section 4.8. and
Electrical Section 4.6.
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-axis Gib is not adjusted properly
Check the adjustment of the X-axis Gibs using the X-axis Gib
adjustment procedures. See section 5.2.1.
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.
Servo Drive failure
See Servo Drive Section 4.5.
Motor failure
See Motor Section 4.4.
3.2.3 Axis Will Not Jog
The system powers up but will not respond to the jog command.
Do the following Service Codes and procedures:
Code 33
Software Identification. This is needed if you call Customer Service.
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
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
E-Stop reset button
Press the E-Stop reset button on the side of the pendant.
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 Cable Interconnection 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:
