SINAMICS G120 built-in frequency converter

SNAMICS G120It is a modular frequency converter composed of multiple different functional units. The two main units are:

●Control unit（CU）

●Power module（PM）

The control unit can control and monitor the power module and the connected motor in several different ways. The power range of the motor supported by the power module is 0.37kW to 250kW. The power module is controlled by the microprocessor in the control unit. The use of high-performance IGBT motor voltage pulse width modulation technology and selectable pulse frequencies makes the motor operation extremely flexible and reliable. Multiple protection functions can provide a higher level of protection for the motor.

The future oriented modular design concept provides a high degree of flexibility for frequency converters:

- Each component can improve the existing frequency converter system

Users can choose and combine according to their needs

- You can only purchase the corresponding modules for the required functions

- Module replacement can be carried out while the power is on(hot-swapping)

- Removable wiring terminals

The replacement of modules is simpler, making maintenance more convenient

●The integration of security protection functions enables it to be better applied to devices and factories with security protection requirements

●Provide stronger supportPROFIdrive Profi l 4.0ofPROFIBUScommunication
