The drive operates from a supply voltage range of 180-264VAC at 48-63 Hz, drawing a rated input current of 5.7 A. It provides a 0-230VAC, 3-phase output with continuous current of 5.0 A and a frequency range of 0-400 Hz. Control voltage is 24V sink/source, and the unit measures 260 x 130 x 180 mm (10.20 x 5.10 x 7.1 in) with a weight of 4.31 kg (9.5 lb).
Industrial Applications
This VFD excels in applications requiring variable speed and torque control. Typical uses include:
-
Conveyor systems – The sensorless vector control maintains consistent speed even under varying load, improving throughput and reducing mechanical stress.
-
Pumps and fans – Energy-saving functions and PID algorithm capability allow precise flow or pressure control, cutting energy consumption significantly.
-
Lifting equipment – The integral IGBT brake and high overload capacity provide safe, controlled stopping, essential for hoists and cranes.
With its robust IP20 enclosure and zero-stacking capability up to 50°C, the 22B-B033N104 adapts to demanding industrial environments.
Installation & Setup Guidance
Mount the drive on a flat, vertical panel with adequate clearance for airflow. Do not mount drives directly above each other; leave at least 100 mm of free space above and below. Connect incoming 3-phase power to the input terminals and the motor to the output terminals, ensuring correct phase sequence. Use the LED keypad to set motor parameters such as voltage, current, and frequency. For remote operation, connect an accessory keypad or use the RS485 port for network control. Always follow local electrical codes and use appropriate fuses or circuit breakers.
Maintenance & Reliability
Periodically inspect the drive for dust accumulation on the heatsink and fans, as overheating reduces lifespan. Check all terminal connections for tightness every six months. The drive includes overload protection, ramp regulation, and flying start, which help prevent faults and extend service life. Its regenerative function returns energy to the supply, lowering operating costs. With proper care, the 22B-B033N104 provides years of dependable service.
Compatibility & Integration
The built-in RS485 port supports daisy-chain wiring, making it easy to integrate with PLCs and HMIs. For advanced connectivity, add optional communication modules for ProfiBus, DeviceNet, BACnet, ControlNet, LonWorks, or RS232. The drive also supports premier integration with the Studio 5000 Design environment, simplifying setup and diagnostics in Rockwell Automation systems.
Buying Guide
Before purchasing, verify your motor's voltage, current, and horsepower to ensure compatibility. The 22B-B033N104 is rated for 10 HP at 240VAC, 3-phase. If you need remote control, order the optional remote keypad separately. PLC Source PRO stocks genuine Allen-Bradley parts, providing fast shipping and reliable support for your automation needs.
