Centrifugal Pumps - Typical Types Include Influent, Effluent, and Booster

Required Drive Features: The drive can control the rate of acceleration and deceleration of the motor and load. These features control the amount of time the drive takes to increase or decrease the output during speed control. Each application has specific requirements for I/O. Analog I/O is generally used to read process signals and output signals proportional to drive status. Analog I/O is generally Voltage (0-10V) or Current (0(4)-20mA). The type and number required by the application must match the drive. Applications that involve multiple drives or drives controlled by PLC or other supervisory device often require communications via a defined network. Some applications have mechanical resonance points that cause the mechanics (shafts, belts, etc.) to oscillate. These oscillations can rapidly cause mechanical failure. Each application has specific requirements for I/O. Digital I/O is generally used to control the drive (Start, Stop, Jog, etc.) and annunciate

A Device for Moving Product from One Place to Another

A device for moving product from one place to another using a continous belt that is rotated by rollers on each end. Required Drive Features: Each application has specific requirements for I/O. Analog I/O is generally used to read process signals and output signals proportional to drive status. Analog I/O is generally Voltage (0-10V) or Current (0(4)-20mA). The type and number required by the application must match the drive. Applications that involve multiple drives or drives controlled by PLC or other supervisory device often require communications via a defined network. Each application has specific requirements for I/O. Digital I/O is generally used to control the drive (Start, Stop, Jog, etc.) and annunciate the drive status. High performance applications often demand nearly instant response to changes in speed or torque commands or input status changes. The higher the dynamic response, the more capable the drive is in meeting these demands. Motors are ra

A Moving Arm or Controlled Rollers Used to Move a Part of a Package

A moving arm or controlled rollers used to move a part of a package from one conveyor to another conveyor or bin. Required Drive Features:  Each application has specific requirements for I/O. Digital I/O is generally used to control the drive (Start, Stop, Jog, etc.) and annunciate the drive status. High performance applications often demand nearly instant response to changes in speed or torque commands or input status changes. The higher the dynamic response, the more capable the drive is in meeting these demands. Some processes require some basic logic functions (timers, boolean (and/or) logic, etc.) but are too small for a PLC or other logic controller. A squirrel-cage motor slips under load. To compensate for this, the frequency can be increased as the motor torque increases. All applications operate over a given speed range, defined as the ratio of maximum continuous speed to minimum continuous speed. Sensorless Vector is a motor control method that is oft

A Screw in a Confined Trough or Tube, Used to Move Material

A screw in a confined trough or tube, used to move material by rotating the screw. In some cases, the auger is also used for mixing and cooking. Required Drive Features: The drive can control multiple independent rates of acceleration and deceleration for the motor and load. These features control the amount of time the drive takes to increase or decrease the output during speed control. Each application has specific requirements for I/O. Analog I/O is generally used to read process signals and output signals proportional to drive status. Analog I/O is generally Voltage (0-10V) or Current (0(4)-20mA). The type and number required by the application must match the drive. Applications that involve multiple drives in a coordinated system often benefit from a common bus configuration. Drives are connected via their DC bus rather than the AC line. It allows energy to be shared between drives and reduces the number of components. Specifies the amount of base speed tha
