Motion Control Troubleshooting
This section covers the determination of motion-related problems within the QuickStick HT
transport system.
Table 8-6: Motion Control Related Troubleshooting
Symptom Problem Description Corrective Action
Material slips while the vehicles
are in motion.
Vehicle is not designed to carry
that specific material.
Make sure that the vehicle design
is correct.
Vehicle is not holding the material
securely.
Make sure that all material con-
tact surfaces are clean.
Motion configuration issue. Make sure that the vehicle accel-
eration is correct.
Make sure that the vehicle speed
is correct.
Make sure that the PID values are
correct.
Vehicles do not move smoothly or
motion is noisy.
Debris on the guideway. Make sure that the guideways and
motors are clean.
Misalignment of sections of the
guideway.
Make sure that the joints between
guideway sections are properly
secured and co-planar.
Power or communication to the
affected motors is lost or intermit-
tent.
Make sure that the power and
communication cables to all
motors and motor drives are prop-
erly seated.
Motion configuration issue. Make sure that the PID values are
correct.
Excessive noise when the vehicle
moves from section to section of
the guideway.
Make sure that the motors are
properly mounted and the transi-
tion from one section of guideway
to the next is smooth (sections
must be at the same height).
Vehicles are loosing thrust. Misalignment or wear of sections
of the guideway.
Make sure that the Vehicle Gap is
consistent at all locations on the
guideway.
Make sure that the vehicle and/or
track wear is within tolerance.
Thrust is lost when the vehicle
moves from motor to motor.
Make sure that the Downstream
Gap does not exceed 10% of the
magnet array length.
