Frequently Asked Questions
What is the Allen-Bradley 22A-B017N104?
It is a Rockwell Automation PowerFlex 4 variable frequency drive rated for a 3.7 kW (5 HP) motor, with 240 V-class three-phase input, 17.5 A rated output current, a fixed keypad and RS485 communication.
What is the motor power rating?
The manufacturer specifies 3.7 kW or 5 HP. Motor selection must also account for the 17.5 A output rating and the application's operating requirements.
What input voltage does this drive require?
It requires a nominal 200–240 VAC three-phase supply at 50/60 Hz. The specified permissible input voltage range is 180–265 VAC.
What is the output current rating?
The PowerFlex 4 user manual specifies 17.5 A for catalog number 22A-B017N104. Rockwell's abbreviated product description refers to the same drive as a 17 A class unit.
Is the 22A-B017N104 single-phase or three-phase?
It is a three-phase input drive designed for compatible three-phase AC motors. It should not be treated as a single-phase input model.
What output voltage and frequency are available?
The manufacturer specifies a three-phase output voltage range of 0–230 VAC and a programmable output frequency range of 0–240 Hz. Motor nameplate limits must be respected during configuration.
What motor control method does PowerFlex 4 use?
The PowerFlex 4 supports volts-per-hertz control with slip compensation. This differs from PowerFlex 40 models that provide additional control methods.
Does the drive include a keypad and display?
Yes. It has a fixed digital keypad and LED display for parameter configuration, operational monitoring and fault diagnostics.
Does the drive support RS485 and Modbus RTU?
Yes. The integrated RS485 DSI port supports applicable Modbus RTU functions when the communication parameters and wiring are configured correctly.
Does the drive support dynamic braking?
Yes. An internal brake IGBT is included. A suitable external dynamic braking resistor and protective components are required if resistor-based braking is necessary for the application.
What is the recommended branch circuit fuse rating?
The Rockwell Automation user manual lists a 30 A fuse rating for 22A-B017N104. The final protection arrangement must comply with the manual, applicable electrical codes and the installation conditions.
What is the enclosure protection rating?
The drive is IP20, NEMA/UL Type Open, Frame B and panel-mounted. It requires an appropriately designed electrical cabinet for the surrounding environment.
What is the difference between 22A-B017N104 and 22A-D8P7N104?
Both belong to the PowerFlex 4 family and have a 3.7 kW (5 HP) motor rating. The 22A-B017N104 is a 240 V-class three-phase drive rated 17.5 A, while 22A-D8P7N104 is a 480 V-class three-phase drive rated 8.7 A. They are not voltage-interchangeable.
Is the Allen-Bradley 22A-B017N104 discontinued?
Yes. Rockwell Automation lists a discontinuation date of June 30, 2025. The product remains identifiable for servicing industrial equipment originally designed around this model.
What is the recommended replacement model?
Rockwell Automation identifies 25A-B017N104 as an engineering replacement. Direct interchangeability should not be assumed; electrical ratings, mounting, motor parameters, control wiring and communication compatibility must be reviewed before migration.
What should be checked before ordering?
Confirm the exact 22A-B017N104 catalog number, 3.7 kW (5 HP) motor rating, 200–240 VAC three-phase supply, 17.5 A rated output, Frame B IP20 panel mounting, integrated keypad, RS485 DSI interface, braking requirements, EMC filter configuration and compatibility with the existing motor and control system.
