KEB Servo Drive

Product Description

KEB drives for Multi Application.

 Asynchronous drive technology of the top class

KEB COMBIVERT F5-H (ASCL) and with internal safety F5-L is the result of long lasting model optimization of encoder-less fIeld orientation and o ers as result best speed and torque characteristics with asynchronous motors without encoder feedback.

ASCL

Properties

• high speed stability
• load step response like closed-loop systems
• torque accuracy typically < 3 % MN
• display values with correction adjustment in the system on the y
• operation with output f lters
• low installation costs in case of loss of encoder cable, encoder and encoder interface
• optimized effi ciency in partial load range
• automatic adaption of the motor
• calibration routine of stator- and rotor resistance, main- and leakage inductance and dead time characteristic
• thermal calculation in the motor model
• controller integration symmetrical optimum
• simplif es the Ki/Kp calibration of the exterior closed circuit (speed)
• only one parameter for drive optimization
• speed preset
• exact torque display by
• determination of torque-o sets and elimination in the display
• subtraction of no-load torque of the system (optional)

Potential applications

• crusher drives / shredder
•  centrifuges
• test bench / test systems
•  stirring and mixer units
• meat cutter and mincer
•  mixing plants
•  heat pumps
• hydraulic pumps
• generators
•  machine tools for wood, plastic, metal  

 SCL

Operation of synchronous motors without encoder feedback The optimization of effi ciency, available space and increasing dynamic forces the use of synchronous motors, which can be operated by F5-E (SCL) and F5-P (safety version) now without rotor position feedback in all applications without positioning tasks. The calculated control method of the software has no e ect through external disturbances and leads to high smoothness. Mechanically stressed motors, high frequency special machines or high-volume torque motors are operated more functional and safe with elimination of the encoder system.

Properties

• standstill position detection (calibration without rotation)
• operation with output f lters
• low installation costs in case of loss of encoder line, encoder and encoder interface
•  high dynamic / non-slip rotation
•  reduced installation space / lower weight
• high effi ciency / high availability
• Potential applications
•  driven tools in working stations
•  synchronous process chain in textile machines
•  hybrid drives
•  diesel electric drives in conveyor systems, container or heavy duty vehicles
•  electric drives in boats, yachts and vehicles
•  synchronous extruder
•  injection moulding technology / blow moulding technology
• high frequency pump drives in compressors, screws, vacuum pumps
