Installation & Commissioning Guide

1. Mount the 20F1AND156AA0NNNNN drive vertically in a large, well-ventilated electrical cabinet.
2. Ensure ample space for airflow due to the high current rating.
3. Connect the 3-phase 480V AC power supply to the main input terminals (R, S, T).
4. Wire your large 3-phase motor to the drive's output terminals (U, V, W).
5. Use the embedded I/O for basic control or add optional cards for advanced functions.
6. For vector control requiring high precision, install an optional encoder feedback card.
7. Configure the drive using programming software (Studio 5000 or CCW). Select the appropriate control mode and perform an autotune with the motor.
8. The internal braking transistor is pre-installed. Add an external braking resistor kit for applications requiring rapid stopping.

Professional FAQ & Answers

What is the main advantage of sensorless vector control?
It provides much better low-speed torque and speed regulation than basic V/Hz mode, without needing an encoder. This is ideal for applications like extruders or mixers that need high starting torque.

Why are there no DC terminals on this model?
This version is designed for standard AC line input only. If you need to connect to an external DC bus (common in multi-drive systems), you would need a different model variant with DC terminals.

Can this drive handle a 100HP motor running 24/7?
Yes, the Heavy Duty (HD) rating of 100HP is specifically for continuous operation at full load. Ensure the drive's cooling is not obstructed and the ambient temperature is within limits.

How is the EMC filter configured?
The drive ships with the Common Mode (CM) filter active (jumper removed). This is the standard setting to minimize electrical noise. Only change it if directed by a detailed site EMC plan.

What's the best way to monitor this drive remotely?
Add an optional Ethernet/IP communication card. This allows you to integrate it into a plant network for real-time monitoring, data logging, and control from a central SCADA or PLC system.
