What does a servo drive do?
Servo Drive A device that is a structural unit of a servo system and is used with a servomotor. The servo drive controls the servomotor according to instructions from a PLC or other controller and performs feedback control with signals from an encoder or other component.
What is Kollmorgen WorkBench?
WorkBench is a Graphical User Interface that allows configuration from different Kollmorgen devices.
What is AKD in paper making?
Alkyl ketene dimer (AKD) is the reactive synthetic sizing agent that is used in alkaline or neutral papermaking conditions to provide certain level of hydrophobicity to the paper and board. The sizing mechanism of AKD involves its reaction with the hydroxyl groups on cellulose.
What is difference between VFD and servo drive?
Servo drive systems are capable of quick acceleration and deceleration and can follow exact motion paths whether point to point or with defined contouring. VFDs on the other hand are paired with induction motors and are used in applications that need velocity control.
When would you use a servo driver?
In essence, the role of the servo drive is to translate low power command signals from the controller into high power voltage and current to the motor. Depending on the application, the servo drive can regulate and properly coordinate the motor’s desired position, speed, torque, etc.
What is AKD wax?
AKD WAX is a versatile chemical that easily reacts with substances containing hydrogen atoms in their structural make-up to form an adduct which is highly repellent to water. AKD is an outstanding size for various forms of cellulosic materials especially paper.
What is AKD emulsion?
AKD Emulsion is a standard starch- stabilized, alkyl ketene dimer (AKD) size dispersion, for the sizing of paper and board under alkaline conditions. Our emulsion is uniquely formulated to work effectively with most retention systems currently employed in the paper industry.
Can a VFD run a servo motor?
Using variable frequency drives for the servo motor is quite possible, only if the application is not critical in positioning control purpose.
Is a servo drive an inverter?
The inverter is usually composed of four parts: rectifier unit, high-capacity capacitor, inverter and controller. The servo system is an automatic control system that enables the output controlled quantity of the object’s position, orientation, state, etc. to follow any change of the input target (or a given value).
What is the difference between drive and servo drive?
While a servo drive needs a command signal given to the motor in order to compare the real and desired position of the motor, a VFD directly controls the voltage and frequency supplied to the motor. VFDs are also known by other names such as AC drive, adjustable-frequency drive, inverter, and microdrive.
How is AKD made?
AKDs are waxy materials which are insoluble in water and have a melting point around 50 ºC depending on chain length. Commercial AKD’s are prepared from natural fatty acid sources and stearic acid is mainly used for this purpose.
