Simple Installation Steps

1. Mount the 20F11ND027AA0NNNNN drive vertically on a DIN rail or panel within a protective enclosure.
2. Connect the 3-phase 480V AC power supply to the input terminals (R/L1, S/L2, T/L3).
3. Wire your 3-phase motor to the drive's output terminals (U, V, W).
4. For basic control, use the embedded I/O terminals for start/stop commands and speed reference.
5. The internal braking transistor is ready for use. Connect an external braking resistor if your application requires very fast stopping.
6. Configure motor parameters and settings using a laptop with programming software (CCW) or a removable keypad.
7. Test the system at low speed first, ensuring motor rotation is correct.

Frequently Asked Questions

What's the difference between the 27A and 22A current ratings?
Use the 27A rating for Normal Duty cycles (variable load). Use the lower 22A rating if your motor will run at or near full load continuously (Heavy Duty), as this generates more heat.

Do I need an external EMC filter?
Probably not. This drive includes a built-in filter that is active (jumper removed), which meets requirements for many industrial installations. Check your plant's specific EMC guidelines.

Can I control the motor speed below 1 Hz?
Yes. The drive can output frequencies as low as 0 Hz. For smooth low-speed operation, ensure you configure the motor parameters correctly and consider using sensorless vector control mode.

How do I add a start/stop button?
It's simple. Connect a standard push-button switch between the +24V terminal and one of the digital input terminals on the drive's embedded I/O, then assign that input as "Start" in the software.

Is the internal braking sufficient for a fan application?
Yes, for most fans. The internal transistor can handle normal deceleration. If you need the fan to stop very quickly for maintenance, you may need to add an external braking resistor.
