SINAMICS G150
       SINAMICS G110 chassis units
SINAMICS G150 - the universal drive solution for single drives with high output ratings
         SINAMICS G120 chassis units
SINAMICS G150 cabinet units have been designed for variable-speed drives in machine building and plant construction.

They have been specially tuned to the requirements of drives with quadratic or constant load characteristics with medium performance requirements without regenerative feedback.

The control accuracy of the sensorless vector control is suitable for most applications, and additional actual speed value encoders are therefore superfluous.

SINAMICS G150 offer an economical drive solution which can be matched to the respective customer requirements by a wide range of components and options.    
     
Applications:
It is advantageous to use variable-speed drives wherever bulk, liquid or gaseous materials have to be moved, transported, pumped or compressed.
Such applications basically include:
   
        Pumps and fans
        Compressors
        Extruders and mixers
        Mills
   
Customer benefits and important features  
        Particularly quiet and compact converters using state-of-the-art IGBT power semiconductors and innovative cooling solution.
        Maximum servicing friendliness with easy accessibility to all modules.
        Problem-free interfacing into automation solutions using a standard PROFIBUS interface and various analog and digital interfaces.
        Increase in plant availability through easy, fast replacement of individual modules and power components.
        Simple start-up and parameterization using interactive menus on the user-friendly AOP30 operator panel with LCD incorporating graphics capability and plain text display.
        EnergySaving: If the motor is not required it can be completely shut down using this function. This is done automatically if the system deviation of the technology controller lies below a defined limit value for a time that can be parameterized.
        EnhancedEnergySaving: This function can be used to extend the time for which the drive converter is powered down as a result of the EnergySaving function - in order to save more energy and to avoid unnecessarily starting and stopping the pumps. And an additional spin-off - the pipes are also purged.
        MaintenanceCleaning: A constant flow rate means that suspended particles in the liquids being pumped can be deposited over time. This can reduce the effective pipe diameter or even block the pumps. The MaintenanceCleaning function is used to briefly increase the pump speed to counteract this sediment
build-up.
        WallDepositsPrevention: If tank levels are kept constant over a longer period of time in wastewater treatment systems deposits occur at the edge of the tank. To avoid these deposits, the WallDeposits-Prevention function always varies the set point for the technology controller so that the tank level is permanently raised and lowered.
   
     
Design  
SINAMICS G150 are ready-to-connect AC/AC converters in a standard control cabinet.
A comprehensive range of options permits adaptation to respective requirements.
They are available with cabinet widths from 400 mm upwards in intervals of 200 mm, in various degrees of protection up to IP54, and with two design versions.
   
Version A
offers sufficient space for all available options. Different designs permit the power supply and motor connections to be located at the top or bottom. This results in high flexibility for the plant installation.

   
Version C
is an extremely space-saving version envisaged for applications where the power supply components are accommodated in a central low-voltage distribution and need not be provided again in the control cabinet.
The user-friendly AOP30 operator panel is fitted as standard in the cabinet door for both versions.
