FAQ
Q1: What is the Allen-Bradley 20G14NF050JA0NNNNN?
The 20G14NF050JA0NNNNN is a PowerFlex 755 AC drive designed for 690 VAC, three-phase applications. It is a Frame 6, air-cooled unit with a 50 A output rating.
Q2: What is the normal-duty power rating?
The normal-duty rating is 45 kW with a continuous output current of 50 A. This makes it suitable for applications requiring the corresponding PowerFlex 755 normal-duty rating.
Q3: What is the heavy-duty power rating?
The heavy-duty rating is 37 kW, with a 42 A continuous output-current rating. The heavy-duty rating should be used when selecting the drive for applications with higher overload requirements.
Q4: What input voltage does the 20G14NF050JA0NNNNN use?
This model uses a DC input with precharge and has a nominal DC input voltage of 932 VDC. It is associated with the 690 VAC class of PowerFlex 755 drives.
Q5: Does the drive include dynamic braking?
Yes. The JA0 configuration includes an internal dynamic-braking transistor. An appropriately selected external braking resistor is required when the application needs dynamic braking.
Q6: Does the 20G14NF050JA0NNNNN include filtering?
Yes. Rockwell Automation specifies the model as filtered, with the common-mode capacitor jumper installed.
Q7: What are the dimensions and weight?
The approximate Frame 6 dimensions are 665.5 × 308 × 346.4 mm (26.20 × 12.13 × 13.64 in.). A distributor listing gives the weight as approximately 14.5 kg (32 lb).
Q8: What enclosure and cooling method does it use?
The drive uses an IP20/IP00, NEMA/UL Type Open enclosure and forced-air cooling. It is intended for vertical installation and should be installed with suitable cabinet protection and airflow for the operating environment.
