The LOHER DYNAVERT T frequency converter integrated as SINAMICS G180 into the SINAMICS range has been deployed for over forty years for applications where maximum reliability and availability of the drive are of paramount importance.

SINAMICS G180 thus benefits from the many years of expertise acquired by LOHER Motors & Drives in the manufacture of motors and converters to the extent that the frequency converters are always systematically developed to take into account the requirements of the drive system as a whole.

SINAMICS G180 converters can be supplied for standard voltages 400, 500 and 690 V in the output range up to 6.6 MW. They are available as a compact unit, a cabinet system or a cabinet unit, with air or liquid cooling, for operation with synchronous and induction motors.

Output ranges of SINAMICS G180 (higher outputs with 400 and 500 V cabinet units available on request)

A wide range of add-on electrical components allow the drive system to be optimized for specific requirements. Configuring is greatly simplified by predefined interfaces and commissioning is speeded up by the preassignment of parameter settings at the factory.

The accuracy of the sensorless vector control makes the converter an ideal partner for many types of drives, such as those used for pumps, fans, centrifuges, presses, extruders or compressors, and an additional actual speed value encoder is therefore superfluous.

Appropriate encoder evaluation units are available for the SINAMICS G180 converters so that they can address applications that require an encoder for plant-specific reasons.

The SINAMICS G180 can be flexibly integrated into any automation concept whether it employs a conventional control or a bus system.

Apart from the standard converter interface (compliant with NAMUR NE37), the following can also be supplied as options to provide communication with the supervisory control system:

• PROFIBUS DP
• Modbus RTU
• Modbus TCP
• CANopen
• Ethernet (PROFIBUS DP with Ethernet-PROFIBUS converter)

Optionally available peripheral boards can be selected to add the following inputs/outputs to the converter:

• Digital and analog inputs and outputs
• 2 PTC thermistor inputs for ATEX-certified motor temperature monitoring for motors in hazardous zones (prewarning/trip)

Дизайн

Platform concept

All of the SINAMICS G180 versions are consistently based on an integrated, standardized, common, modular platform concept. Shared hardware and software components, as well as standardized tools for dimensioning, configuring and commissioning tasks ensure a high level of integration between all components.

All devices - from the lowest rating class in compact unit form to the largest version in the form of an air-cooled or liquid-cooled cabinet unit - have the same features with a virtually identical scope of functions.

All frequency converters in the SINAMICS G180 range operate with the Control Board. All Control Boards utilize the same firmware and all are operated via the Inverter Management Software IMS. Both the IMS and the firmware can be upgraded and downgraded as required to facilitate communication.
