FAQ
FAQ
Q1: What is the Allen-Bradley 20F14NF142JN0NNNNN?
A: It is a PowerFlex 753 variable frequency drive designed for industrial motor speed and torque control, with a 690 VAC voltage class and a 142 A normal-duty current rating.
Q2: What is the rated output power of this drive?
A: The rated output power is 132 kW for normal-duty operation and 110 kW for heavy-duty operation.
Q3: What input configuration does this model use?
A: It uses a DC input with a precharge circuit. The nominal DC bus voltage for this 690 V class drive is approximately 932 VDC.
Q4: Does the drive include an internal dynamic-braking transistor?
A: No. The N configuration indicates that an internal dynamic-braking transistor is not included. An external braking solution may be needed if the application requires dynamic braking.
Q5: Does this model include an EMC filter?
A: Yes. The J configuration indicates that filtering is included and the common-mode capacitor jumper is installed.
Q6: What are the dimensions of the 20F14NF142JN0NNNNN?
A: The reference dimensions for the Frame 6 open-type unit are approximately 665.5 mm high × 308 mm wide × 346.4 mm deep. Check the official mechanical drawing for installation clearances and mounting-hole positions.
Q7: What is the net weight of this drive?
A: The Rockwell Automation CAD catalog lists a net product weight of approximately 38.555 kg (85 lb). Shipping weight may be higher due to packaging.
Q8: Does this model include a built-in operator interface?
A: No. This configuration is supplied without a Human Interface Module (HIM). A compatible optional HIM or external configuration tool can be used for commissioning, parameter setup, and diagnostics.
