22kw – 1000kw Variable Frequency AC Inverter Drives for Conveyor

Conveyors are used in a broad range of industries and applications to move packaged goods, assemblies, process byproducts, or any material from one place to another. A process designer will typically look for opportunities to use the force of gravity to accomplish product movement. Electric motors are commonly used when gravity cannot be employed or when the speed of a gravitational fall needs to be controlled.
Airports, mines, cement plants, distribution facilities, assembly, and food processing plants all utilize conveyors. Conveyors are typically constant torque loads, meaning the required torque to drive a conveyor is independent of speed. A fixed amount of torque is also required to overcome the frictional, or machine drag, portion of the total load. Conveyors can have nominal amounts of friction and machine inertia for which to compensate.

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

Features of G7 matching conveyor application



Pulse Train I/O for speed control

Control speed of parallel or series conveyors by use of Pulse Train I/O function in the drive. Eliminates the need for complex pulse to analog converter.

Momentary Powerloss Ride-thru
Automatic Fault Restart

The Momentary Powerloss Ride-thru and Fault Restart functions allow the drive to continue operation without the need for attended restart.

Fully adjustable S-Curve and Accel/Decel rates

Smooth starting and stopping is achieved through the drives Accel/Decel and S-Curve characteristics.

Torque Limit

Torque Limit protects the load and other machinery from excessive torque that may occur when the load fluctuates or seizes.

Zero-Servo Function

The Zero Servo Function in the Closed Loop Flux Vector Mode makes a mechanical brake unnecessary for tilt-tray and certain incline conveyors that require a mechanical brake to stop.

Torque Control in Closed loop Flux Vector Mode and Speed Droop control in V/F Control Mode

Operating two or more conveyor motors in series. The load may shift off between motors. The drive allows for load sharing by using Torque Control or Droop Control.

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.
