Technical FAQs

Q1: What is the rated power of the 25B-D024N114?

The drive is rated at 11 kW (15 HP) for both normal-duty and heavy-duty applications.

Q2: What input voltage does this model support?

It is designed for 380–480V AC three-phase input power. The specified input voltage range is approximately 323–528V AC.

Q3: What is the rated output current?

The rated output current is 24 A. The connected motor's rated current should be checked to ensure it is compatible with the drive.

Q4: Does the 25B-D024N114 include an EMC filter?

Yes. The N114 configuration includes an integral EMC filter. This distinguishes it from the corresponding N104 configuration, which does not include an integral filter.

Q5: Which communication protocol does the drive support?

The PowerFlex 525 features embedded EtherNet/IP communication. It also provides an RS-485 interface for compatible communication applications.

Q6: Does this drive support Safe Torque Off?

Yes. The PowerFlex 525 includes a Safe Torque Off (STO) function. Its implementation must follow the manufacturer's safety instructions and applicable machine safety requirements.

Q7: Can the drive control motor acceleration and deceleration?

Yes. Acceleration and deceleration times can be configured through drive parameters to suit the motor, load inertia, and process requirements.

Q8: Does the 25B-D024N114 support sensorless vector control?

Yes. It supports sensorless vector control and V/Hz control. The appropriate control mode should be selected according to the motor and application.

Q9: What could cause an overvoltage fault during motor deceleration?

Possible causes include excessive regenerative energy, a deceleration time that is too short, or unsuitable braking arrangements. Check the fault code, deceleration settings, and braking resistor selection before restarting.

Q10: What should be checked before replacing this drive?

Verify the voltage class, output current, motor power, Frame D configuration, EMC filter, communication settings, safety wiring, and parameter configuration. A replacement should match the original system requirements.
