Allen-Bradley 20F1AND156AA0NNNNN PowerFlex 753 AC Drive 156A

Product Overview

The Allen-Bradley 20F1AND156AA0NNNNN is a variable frequency drive from the PowerFlex 753 series, designed for demanding industrial motor control applications. This unit delivers a rated output current of 156 A and operates on a supply rating of 480 VAC, three-phase. It supports motors up to 125 HP for normal duty and 100 HP for heavy duty. With embedded I/O, multiple control methods (V/Hz, vector, sensorless vector), and an internal dynamic braking transistor, this drive provides flexible, operation. The air-cooled design with an IP20/IP00 open enclosure ensures efficient heat dissipation in panel-mount installations.

Technical Specifications Breakdown

Key parameters for the 20F1AND156AA0NNNNN are listed below for quick reference:

Industry Applications

In conveyor systems, the 20F1AND156AA0NNNNN manages start/stop cycles and variable loads efficiently. For pump and fan applications, its sensorless vector control optimizes energy consumption. The heavy-duty rating (100 HP) makes it suitable for extruders and mixers in processing plants. Compared to similar drives without embedded I/O, this unit reduces external wiring and panel space.

Installation & Setup Guidance

Mount the drive on a flat, vertical panel using the provided mounting holes. Ensure adequate clearance for airflow around the air-cooled enclosure. Connect three-phase 480 VAC supply to the input terminals. The AC input with precharge feature reduces inrush current during startup. For control wiring, use the embedded I/O terminals for start/stop and speed reference signals. Configure the drive via the control methods (V/Hz, vector, or sensorless vector) using a connected HIM or software. Note that this unit does not include a HIM; use an external programming device.

Maintenance & Reliability

Inspect the drive periodically for dust accumulation on the heatsink and fan. Clean with low-pressure dry air to maintain cooling efficiency. Check all power and control connections for tightness annually. Monitor the internal dynamic braking transistor for signs of overheating. The IP20/IP00 enclosure protects against solid objects but not moisture; install in a dry, clean environment. For filtered EMC performance, ensure the CM jumper is removed as specified.

Compatibility & Integration

This drive integrates with Allen-Bradley control systems via embedded I/O and optional communication modules (not included). It supports standard motor feedback devices for vector control. The DC bus with DC filtering ensures smooth operation when connected to common DC bus configurations. For multi-drive systems, verify compatibility with the PowerFlex 753 series architecture.

Selection Guide & Purchasing Advice

When selecting the 20F1AND156AA0NNNNN, confirm your motor's horsepower and duty cycle match the 125 HP ND / 100 HP HD ratings. Verify supply voltage is 480 VAC three-phase. For applications requiring a HIM, order separately. AutoDCSTech stocks this drive and can assist with lifecycle status and availability. Contact our team for bulk pricing or expedited shipping.
