Industrial Applications

1. Automated Conveyor Systems

In modern manufacturing and logistics, conveyor belts require precise speed control for material flow and sequencing. The SINAMICS G120C ensures smooth acceleration and deceleration, preventing material damage and optimizing throughput. Its robust overload capacity handles start-up peaks and temporary jams, while PROFIBUS DP allows integration into plant-wide control systems.

Problem Solved

Inefficient material handling due to imprecise speed control, energy waste, and system downtime caused by motor overloads in conveyor systems.

2. Industrial Pump and Fan Control

For HVAC systems, water treatment, and industrial processes, pumps and fans often require variable speed operation to match demand, leading to significant energy savings. The G120C's V/f ECO linear/square-law control is ideal for these quadratic torque loads, optimizing energy consumption while maintaining system efficiency across various flow rates.

Problem Solved

High energy consumption and inefficient operation of fixed-speed pumps and fans in industrial and commercial buildings.
