Frequently Asked Questions (FAQ)

Q1: What is the primary function of the 25B-D017N114?

It is a PowerFlex 525 adjustable frequency AC drive used to control the speed and torque of three-phase AC motors. It is designed for networked industrial applications such as conveyors, fans, pumps, and mixers, offering embedded EtherNet/IP communication and integrated safety features .

Q2: Does the 25B-D017N114 have built-in EtherNet/IP?

Yes. The drive features embedded EtherNet/IP communication, enabling seamless integration with Allen-Bradley PLCs and Studio 5000 Add-On Profiles without requiring additional communication modules. It also supports RS-485 (Modbus RTU) and USB programming .

Q3: What safety functions does this drive include?

The 25B-D017N114 includes Safe Torque-Off (STO) as standard, certified to SIL 2 / PLd Category 3. This removes rotational power to the motor without removing power from the drive, enabling faster restart after a safety demand .

Q4: What is the difference between N104 and N114 suffix?

The primary difference is EMC filtering. The -N104 suffix indicates a drive without an integrated EMC filter, while the -N114 suffix (this model) includes an integrated CE-compliant EMC filter for compliance with electromagnetic compatibility standards .

Q5: Is the 25B-D017N114 a direct replacement for PowerFlex 40 drives?

Yes, with considerations. Rockwell Automation designed the PowerFlex 525 as the official engineered replacement for the discontinued PowerFlex 40 (22B series). The catalog numbering follows a clean migration pattern (22B → 25B). However, STO wiring is required — the drive will not run unless the STO inputs are properly wired (or jumpered if not using the safety function) .
