Device design
SINAMICS G110D is a compact converter in IP65 degree of protection where the Control Unit (CU) and Power Module (PM) function units are combined in one device.
The closed-loop control electronics controls and monitors the power electronics and the connected motor in several different control types that can be selected. The digital inputs and analog inputs on the device mean that sensors can be simply and directly connected at the drive. The input signals can either be directly linked within the converter and initiate local responses independently or they can be transferred to the central control via AS-Interface for further processing within the context of the overall plant.
The power electronics supplies the motor in the power range from 0.75 kW to 7.5 kW. It is controlled (open-loop) from the microprocessor-based control. State-of-the-art IGBT technology with pulse-width-modulation is used for highly reliable and flexible motor operation. Comprehensive protection functions provide a high degree of protection for the converter and motor. The unusually low profile mechanical design is optimized so that the device can be directly used in the plant or system. The compact converter has the same drilling dimensions for all power ratings (standard footprint). Further, the dimensions are identical to those of the SINAMICS G120D frequency converter. This significantly simplifies the mechanical design, installation and retrofit of a system.
