Where It Works Best
- Manufacturing: Improves torque and speed control on assembly lines and packaging equipment.
- Water/Wastewater: Maintains pump performance while reducing mechanical wear and energy waste.
- HVAC Systems: Regulates airflow and temperature efficiently in commercial buildings.
- Material Handling: Enhances throughput and system responsiveness in conveyors and lifts.
Safety Built In
Designed for IEC 61508 compliance, the drive includes Safe Torque-Off (STO) functionality, meeting ISO 13849-1 SIL2/PLd standards. STO disables the motor’s torque-producing energy without removing power, enabling faster restarts and reducing hardware complexity.
Smarter Setup and Faster Programming
Commissioning the PowerFlex 525 is fast—even without powering up the drive. Use the onboard USB port and Connected Components Workbench (CCW) software to configure parameters, update firmware, and deploy applications.
Programming Features Include:
- AppView & CustomView: Preloaded or user-defined parameter groups
- Over a dozen parameter sets: Including I/O configuration, communication, and diagnostics
- No external power needed: Configure before installation
Flexible Communication Options
The 525 offers dual-port embedded EtherNet/IP, along with optional cards for:
- DeviceNet
- PROFINET
- PROFIBUS DP
- Modbus RTU
With real-time communication and diagnostic feedback, you can implement predictive maintenance and advanced system coordination with ease.
