Industrial Applications

1. Conveyor Belt Systems in Manufacturing

This drive can precisely control the speed and torque of motors driving conveyor belts, allowing for optimized material flow and preventing jams. The 15.0 kW low overload capacity is suitable for steady-state material transport, while the 11.0 kW high overload handles momentary increased loads. The integrated Safe Torque Off (STO) function provides critical safety for emergency stops or maintenance.

Problem Solved

Ensures smooth, controlled movement of goods, adapts to varying production rates, and provides critical safety to prevent personnel injury and equipment damage.
