Motor/Drive Combination

Siemens Industry released pre-determined combination motor/drive packages that are power-matched for 480V high-overload operation through a 20 hp range, with I2T protection from thermal damage provided as a standard in both the motor and the drive components. The Siemens Intelligent Operator Panel (IOP) is included with these packages, allowing step-by-step drive start-up. Application macros are provided in the Sinamics G120C drive; the terminals are pre-assigned at the factory and the parameters are automatically set. The company’s cast-iron SIMOTICS SD100 motors feature inverter duty ratings in a 4:1 speed range for constant torque and 20:1 speed range for variable torque. Communications selections include RS485 with USS and Modbus protocols, although a Profibus variant is also offered.
