FAQ
FAQ
Q1: What is the Allen-Bradley 20G11BC1K2AN4NNNNN?
A1: It is a PowerFlex 755 air-cooled AC drive designed for high-power industrial motor control applications.
Q2: What is the input voltage of this drive?
A2: The 20G11BC1K2AN4NNNNN belongs to the 400 VAC, three-phase PowerFlex 755 configuration family.
Q3: What is the current rating?
A3: This catalog family is rated at 1,175 A, making it suitable for large motor-drive installations.
Q4: What are the power ratings of the 20G11BC1K2AN4NNNNN?
A4: The corresponding 400 VAC Frame 9 configuration is rated at approximately 800 kW for low-duty applications, 710 kW for normal duty, and 560 kW for heavy-duty operation.
Q5: Does this model use air cooling?
A5: Yes. The catalog description identifies the 20G11BC1K2AN4NNNNN as a PowerFlex Air Cooled 755 AC Drive.
Q6: Does the drive support EtherNet/IP?
A6: The PowerFlex 755 platform supports EtherNet/IP communication, and the configuration family uses integrated network capabilities for industrial control-system integration.
Q7: What type of enclosure is used?
A7: This high-power Frame 9 family uses a cabinet/MCC-style construction rather than the compact enclosure used by smaller PowerFlex 755 frames. Installation space and cabinet ventilation should therefore be checked against the applicable installation documentation.
Q8: Is 20G11BC1K2AN4NNNNN the same as 20G11BC1K2AN0NNNNN?
A8: No. They are separate catalog numbers within the same PowerFlex 755 family. Rockwell’s documentation lists the AN0, AN2, and AN4 versions as distinct configurations, so the complete catalog number should be matched when selecting a replacement.
