Vector Control Drives of AC Machines for Lift Control
Lift control is widely used in industries like mining, ports, building and so on. It requires the control stable and safe in any time and avoiding any out of control case.
Application Challenges
· Motor and Drive sizing
Conveyors requires a good deal of load and speed calculations,
combined with actual testing to ensure proper size (power) requirements.
· Smooth product motion
Acceleration/Deceleration times combined with S-Curve “smoothing” characteristics need fine-tuning to ensure the product is not damaged and/or moved out of position for staging to subsequent processes.
· Rapid deceleration or downhill speed control of conveyors cause load regeneration in drives.
Care should be taken to ensure proper sizing of a drive’s dynamic braking package or regenerative converter,
to prevent drive overvoltage faults.
· Electronic Gearing
Follow an external encoder to synchronize conveyor with other sections of the process
· Coordinate conveyor motion with external machine axes
· Reduce application development time

Tips:
A variable-frequency drive (VFD) is a system for controlling the
rotational speed of an alternating current (AC) electric motor by
controlling the frequency of the electrical power supplied to the
motor. A variable frequency drive is a specific type of
adjustable-speed drive. Variable-frequency drives are also known as
adjustable-frequency drives (AFD), variable-speed drives (VSD), AC
drives, microdrives or inverter drives. Since the voltage is varied
along with frequency, these are sometimes also called VVVF
(variable voltage variable frequency) drives.
