Weighing 2.29 kg, this drive excels in applications requiring high starting torque and precise speed regulation through its integrated Sensorless Vector Control (SVC). Whether managing conveyors, fans, or processing equipment, the 22B-B012N104 offers a perfect balance of flexibility and power for 240V 3-phase industrial environments.

Technical Specifications

Installation & Engineering Guide

Adhering to correct engineering practices ensures the longevity of your PowerFlex 40 system:

• Thermal Management: This drive generates 125 Watts of power loss during full-load operation. Ensure the control cabinet provides adequate airflow to keep ambient temperatures between -10°C and 50°C.
• Mounting Versatility: The 2.29 kg chassis is compatible with 35mm DIN rail for fast installation or direct panel mounting for increased vibration resistance.
• I/O Integration: Utilize the 4 discrete inputs and 2 analog inputs (0-10V / 4-20mA) to interface directly with local sensors and PLC logic without additional expansion modules.
• Short Circuit Protection: With a 100,000A short circuit rating, ensure branch circuit protection is sized according to NEC/CEC requirements for 240V systems.

Engineering Advantages

• StepLogic™ Functionality: Allows the drive to function as an independent position controller or time-based logic controller, reducing the need for an external PLC in simple applications.
• Sensorless Vector Control: Captures high starting torque and maintains tight speed regulation even under fluctuating load conditions.
• Zero Stacking™: Designed for side-by-side mounting to save valuable panel space without compromising thermal performance.
• Dynamic Braking: Includes an internal brake IGBT, facilitating rapid deceleration and efficient energy dissipation when paired with an external resistor.

Technical FAQs

Q1: What is the maximum frequency output for the 22B-B012N104?
A1: The drive is programmable to output up to 400 Hz, making it suitable for high-speed spindles and specialized industrial motors.

Q2: Does the 2.29 kg weight affect my mounting configuration?
A2: Not significantly; the 2.29 kg (approx. 5 lbs) weight is standard for Frame B drives and is safely supported by standard industrial 35mm DIN rails or M5 panel screws.

Q3: How does Sensorless Vector Control benefit my application?
A3: SVC provides better speed regulation and higher torque at low speeds compared to standard V/Hz control, making the 22B-B012N104 ideal for heavy-start applications like conveyors or mixers.
