Description
The SINAMICS G120 has a completely new integrated concept for thermal motor protection.
There are numerous possibilities of effectively protecting the motor but at the same time
ensuring high motor utilization. The basic philosophy of this innovative concept is to detect
critical thermal states, output warnings and initiate the appropriate responses. By responding
to critical states it is possible to operate the motor at the thermal power limit and to avoid,
under all circumstances, an immediate shutdown (where the inverter is tripped).
