• Series: PowerFlex 525
• Part Number: 25B-D2P3N114
• Type: AC Variable Frequency Drive (Inverter)
• Input Voltage: 380–480V AC, 3-phase
• Power Rating: 0.75 kW (1 HP)
• Output Current: 2.3 A
• Frame Size: A

Key Features

• Built-in EtherNet/IP communication
• Integrated safe torque off (STO) safety function
• USB programming port for quick setup
• Supports Modbus RTU and EtherNet/IP
• Compact modular design for easy installation
• Suitable for global industrial voltage standards

Function (Simple Explanation)

This device is a motor speed controller:

• Converts fixed AC power → variable frequency output
• Controls motor speed from 0 to rated RPM
• Provides soft start/stop and torque control

So instead of direct ON/OFF motor control, it enables precise speed regulation.

System Role

PLC / HMI system
→ communication or analog reference
→ PowerFlex 525 drive
→ AC motor

It acts as the middle controller between PLC and motor.

Typical Applications

• Conveyor systems
• HVAC fans and pumps
• Packaging machinery
• Mixing equipment
• Material handling systems
• General industrial automation

Advantages

• Energy saving by variable speed control
• Reduces mechanical stress on motors
• Built-in Ethernet reduces external wiring
• High reliability industrial design
• Easy commissioning via keypad or software
• Wide control flexibility (torque/speed modes)

Precautions

• Must match motor voltage (do not run 230V motor on 480V drive)
• Requires proper grounding and shielding
• Incorrect parameter settings may cause motor faults
• Must ensure proper cooling/ventilation in cabinet
• STO safety function must be wired correctly if used
