Frequently Asked Questions
What is the Allen-Bradley 22A-B012N104?
It is a Rockwell Automation PowerFlex 4 variable frequency drive rated for 2.2 kW (3 HP) and 12 A, with 240 V-class three-phase input, an integrated digital keypad and RS485 communication.
What motor power does this drive support?
The manufacturer specifies a rated motor power of 2.2 kW, equivalent to 3 HP. The connected motor must also meet the drive's rated current and operating requirements.
What input voltage is required?
The drive is designed for a nominal 200–240 VAC three-phase supply at 50/60 Hz. Verify supply tolerance requirements using the applicable PowerFlex 4 user manual.
What is the rated output current?
The manufacturer specifies a 12 A output current rating for catalog number 22A-B012N104.
Is this a single-phase or three-phase input drive?
It is a three-phase input drive intended for compatible three-phase AC motors. It should not be confused with single-phase-input PowerFlex 4 variants.
What motor control method does PowerFlex 4 use?
The PowerFlex 4 supports volts-per-hertz control with slip compensation, providing configurable frequency control for compatible AC motors.
Does the drive include a keypad?
Yes. It has an integrated LED display and fixed digital keypad for parameter programming, drive monitoring and fault diagnostics.
Does the 22A-B012N104 support RS485?
Yes. It includes an RS485 DSI communication interface. Modbus RTU communication is supported through compatible wiring and configuration.
Does the drive support dynamic braking?
Yes. Rockwell Automation lists an internal brake IGBT for this model. An appropriately rated external braking resistor and protective components may be needed for applications requiring dynamic braking.
What is the enclosure protection rating?
The drive uses a Frame B, IP20, NEMA/UL Type Open panel-mounted enclosure. Installation inside an appropriate industrial electrical cabinet is required for environmental protection.
Does this model have an integrated EMC filter?
No. The manufacturer specifies that the 22A-B012N104 has no integrated CE-compliant EMC filter. External filtering may be required for particular installations.
Is the Allen-Bradley 22A-B012N104 discontinued?
Yes. Rockwell Automation lists June 30, 2025 as the discontinuation date. The model remains relevant for servicing equipment designed around the PowerFlex 4 drive.
What replacement does Rockwell Automation recommend?
Rockwell Automation identifies 25A-B011N104 from the PowerFlex 523 family as an engineering replacement. It has an 11 A output rating and is not automatically a direct drop-in replacement for the 12 A PowerFlex 4 drive.
Can 25A-B011N104 directly replace 22A-B012N104?
An engineering review is required. Check the connected motor's full-load current, drive overload capacity, power and control wiring, parameter mapping, communication setup, enclosure dimensions and installation requirements before substitution.
What is the difference between 22A-B012N104 and 22A-B017N104?
Both belong to the PowerFlex 4 family and use 240 V-class three-phase input. The 22A-B012N104 is rated 2.2 kW (3 HP) and 12 A, while the 22A-B017N104 is rated 3.7 kW (5 HP) and belongs to a higher output-current class.
What should be checked before ordering?
Confirm the exact 22A-B012N104 catalog number, 2.2 kW (3 HP) motor rating, 200–240 VAC three-phase supply, 12 A output current, Frame B IP20 panel mounting, integrated LED keypad, RS485 DSI communication, braking requirements, EMC filter configuration and compatibility with the existing motor and control cabinet.
