2 Solution
integrated display of the LOGO! logic module, the setpoint pressure, the current
pressure and the speed of the pump are displayed as bar diagrams.
Advantages
The solution presented here offers you the following advantages:
•
Cost-effective and stepless speed control
•
Simple combination of drive tasks with sensor and control functions by
combining a SINAMICS V20 with a LOGO!
•
Protection and supervision function of the motor via SINAMICS V20
•
Excellent energy efficiency by a motor output adapted to the consumption
•
Direct display of messages and device states on the integrated display of the
LOGO!
•
Simple modification of parameters of the control functions of the LOGO! via the
integrated operating function of the LOGO!
•
Time-saving by implementing your individual application by means of an
executable, tested example project
•
Planning security by adapted products adapted to the example application
•
Avoid errors thanks to step-by-step instructions
Fields of application
This application is especially suitable for a cost-effective and comfortable speed
control of motors. The motor speed is changed steplessly to react to disturbances
in the system.
This application is suited especially for the following industries and scenarios:
•
Water supply/sewage systems
•
Oil and gas industry
•
Filling plants
•
Building management: pump control
•
Machine management: extraction plants, mixing plants
Assumed knowledge
Basic knowledge about STEP 7 TIA Portal, LOGO! and SINAMICS V20 is
assumed.
