This section covers the determination of motion related problems within the MagneMover
LITE transport system.
Table 7-7: Motion Control Related Troubleshooting
Symptom
Problem Description
Corrective Action
Material slipping on the vehicles.
Vehicle not designed to carry that
specific material.
Ensure the vehicle design is cor-
rect.
Vehicle is not holding the material
securely.
Ensure all material contact sur-
faces are clean.
Motion configuration issue.
Ensure the vehicle acceleration is
correct.
Ensure the vehicle speed is cor-
rect.
Ensure the PID values are correct.
Vehicles not moving smoothly or
movement is noisy.
Debris on the guideway.
Ensure the guide rails and motors
are clean.
Misalignment of sections of the
guideway.
Ensure the guide rail alignment
V-braces are properly installed.
Power or communication to the
affected motors is lost or intermit-
tent.
Ensure the power and communi-
cations cables to all motors are
properly seated.
Motion configuration issue.
Ensure the PID values are correct.
Excessive noise when the vehicle
moves from motor to motor.
Ensure the motors are properly
mounted and the transition from
the rails on one motor to the rails
on the next motor is smooth (rails
should be at the same height).
Vehicles loosing thrust.
Misalignment or wear of sections
of the guideway.
Ensure the Vehicle Gap is consis-
tent at all locations in the trans-
port system.
Ensure the vehicle and/or track
wear is within tolerance.
Thrust lost when the vehicle
moves from motor to motor.
Ensure the Downstream Gap does
not exceed 10% of the magnet
array length.
