FAQs

Q1: What is the primary function of the 22F-D4P2N103?
It is a PowerFlex 4M adjustable frequency AC drive used to control the speed of three-phase AC motors. It provides basic V/Hz control for simple applications such as fans, pumps, and conveyors where networking and advanced features are not required.
Q2: What communication options does this drive support?
The drive features integral RS-485 communication supporting the DSI (Drive Serial Interface) protocol, which is compatible with Modbus RTU. This allows for multi-drop network configurations and programming from a PC using a serial converter module .
Q3: Does this drive include a brake transistor?
No. The 22F-D4P2N103 is configured with the brake IGBT omitted . For applications requiring dynamic braking, an external brake chopper or a different drive model with an internal brake transistor is needed.
Q4: Is the PowerFlex 4M still an active product?
Yes, the 22F-D4P2N103 is currently listed as Active (PM300) by Rockwell Automation . However, the PowerFlex 4M series is an entry-level platform, and Rockwell recommends the PowerFlex 523 or 525 for new designs requiring networking, safety, or sensorless vector control.
Q5: Can I use this drive with a ControlLogix or CompactLogix PLC?
Yes, but with limitations. The PowerFlex 4M communicates via RS-485/DSI (Modbus RTU). To connect to a Logix controller, you would need a third-party Modbus RTU scanner or a serial communication module. For native EtherNet/IP integration, the PowerFlex 525 is the recommended choice.
