Overview
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 mo-
tors 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 con-
verter an ideal partner for many types of drives, such as those
used for pumps, fans, centrifuges, presses, extruders or com-
pressors, 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 applica-
tions that require an encoder for plant-specific reasons.
The SINAMICS G180 can be flexibly integrated into any auto-
mation 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)
