SINAMICS G180 Chassis and Cabinet Units

SINAMICS G180 are compact devices, cabinet systems and cabinet units (air and liquid cooled) for variable-speed drives in plant and machinery construction; which have been specifically designed for applications in oil and gas, the chemical and process industries. They have been specially developed to address the requirements of drives with square law and constant load characteristics.


Special properties of the SINAMICS G180

SINAMICS G180 represents the optimum drive solution that can be adapted to the various industry specific requirements in the core industries using a wide range of options and X options (special, customer-specific options).

  • Communication via conventional terminal strip with freely programmable digital and analog inputs/outputs.
  • SINAMICS G180 are designed for operation with SIMOTICS XP explosion-proof motors and optimized for Ex ec, Ex eb and Ex db types of protection.
  • High level of protection for personnel and equipment is provided through protective separation of the safety extra-low voltage in accordance with IEC/EN 61800‑5‑1 at the analog and digital control inputs and outputs of the power unit.
  • Two control modes for induction motors: Space vector control for standard applications (without feedback) and field-orientated control to address dynamic requirements.
