Industrial Applications

1. Conveyor Systems in Manufacturing

Control the speed of conveyor belts in automated assembly lines or material handling systems.

Problem Solved

Precise speed and torque control (0-240Hz/550Hz output frequency) allows for optimized material flow, reduced wear on mechanical components, and energy savings. The integrated STO provides essential safety for personnel during maintenance or emergency stops, preventing unintended motor restarts. The IP20 rating is suitable for installation within control cabinets.

2. Pump and Fan Control in HVAC/Process Industries

Regulating the speed of industrial pumps and fans in heating, ventilation, air conditioning (HVAC) systems or process control applications to match demand.

Problem Solved

Optimizes energy consumption by precisely controlling pump/fan speed based on demand, rather than using mechanical throttling (V/f control up to 550 Hz). The Class A filter ensures compliance with EMC standards, minimizing interference with other sensitive equipment. The 1.1kW (low overload) or 0.75kW (high overload) power rating is suitable for small to medium-sized pumps/fans.

3. Packaging Machinery Motor Synchronization

Synchronizing multiple motors in packaging lines for tasks like filling, sealing, and labeling, ensuring smooth and precise operation.

Problem Solved

The drive's ability to provide precise motor control and communication via USS/MODBUS RTU enables synchronization of different machine sections, improving product quality and throughput. The compact size (173x73x155mm) allows for integration into space-constrained packaging machines. Digital and analog I/O allow for integration with sensors and actuators for feedback and control.
