Background
Your machine axes require power and control signals to work. If either of those are disrupted you can lose any or all axis motion. If all of your motors are not working, go to All Axes Won't Move When Commanded - 1500MX
Examine the Servo Drives
Reason: The servo drive has an error present.
-
Examine the Servo Drives in the electrical cabinet for an error code.
-
Power cycle the machine to see if the error reappears.
-
If so, contact Technical Support.
Check Motor Coupling
Reason: There’s a loose axis motor coupling.
-
Jog the axis and listen to determine if you can hear the motor run.
-
Examine the coupling and make witness marks to determine if the motor’s turning but the screw isn’t.
Check Lubrication System
Reason: Oil isn’t getting to the ways and ball screw.
-
Examine the oil level in the oiler.
-
Investigate the oiling system for lack of oil and/or plugged lines.
Push Fresh Oil Through System
Reason: There’s oil residue from long-term storage.
-
Repeatedly pump oil and slowly jog the axis.
Clean the Ball Screw
Reason: There’s debris on the ball screw.
-
Clean the ball screw.
-
Debris on the ball screws can rapidly accelerate wear and reduce the lifespan of your machine. Evaluate if additional measures are required to protect your machine’s ball screws and ways (like supplemental dust collection.)
