Installation & Setup Overview

1. Install this 20F1AND125AA0NNNNN drive vertically in a large, well-ventilated electrical cabinet.
2. Connect the 3-phase 480V AC power supply to the main input terminals.
3. Wire your large 3-phase motor to the drive's output terminals.
4. For basic control, use the embedded digital and analog I/O terminals.
5. Install optional cards into the three slots if your application requires added safety, precise feedback, or network communication.
6. Configure the drive using a laptop with Rockwell software (Studio 5000 or CCW) or a removable keypad. Set the control mode based on your needs.
7. Important: Complete a full commissioning procedure, including motor autotune if using vector control, before applying full load.

Expert Answers to Your Questions

What's the difference between Normal Duty and Heavy Duty ratings?
Normal Duty (100HP) is for typical applications with variable loads. Heavy Duty (75HP) is for applications where the motor runs at or near full load continuously, which generates more heat inside the drive.

Can I use this drive for a constant torque application like a conveyor?
Yes. For constant torque needs, use the Sensorless Vector control mode. It provides better low-speed torque and speed regulation compared to basic V/Hz mode.

What optional cards are most commonly added?
The Safe Torque Off (safety) card is popular for meeting machine safety standards. The Ethernet/IP communication card is also widely used for easy integration into modern factory networks.

Why is there no keypad, and how do I change settings?
Omitting the keypad reduces cost and panel space. You can connect a standard USB cable to the port and use free software on a PC for full configuration, which is often easier for complex setups.

How do I handle the EMC filter jumper?
The drive ships with the EMC filter "jumper out," meaning it's active to reduce electrical noise. Only remove the jumper (making it "in") if instructed by a detailed EMC compliance plan for your specific installation.
