FAQ
FAQ
Q1: What is the 20G11BC1K5JN2NNNNN?
A: It is an Allen-Bradley PowerFlex 755 AC drive intended for high-power industrial motor control. The unit uses a forced-air-cooled Frame 9 construction and a 600 mm deep MCC-style configuration.
Q2: What is the input voltage and current rating?
A: The drive is rated for 400 VAC, three-phase input and has a 1480 A current rating.
Q3: What are the power ratings of this model?
A: The published ratings are 900 kW for low-duty operation, 850 kW for normal-duty operation, and 710 kW for heavy-duty operation. The correct rating depends on the motor load and required duty cycle.
Q4: Does the drive have built-in EtherNet/IP?
A: Yes. Embedded EtherNet/IP is included in the 20G11BC1K5JN2NNNNN configuration, allowing it to interface directly with compatible industrial control networks.
Q5: What type of cooling does it use?
A: This model uses forced-air cooling. Rockwell’s product information also identifies the associated fan as a backward-curved centrifugal type.
Q6: What enclosure and mounting configuration are specified?
A: The drive is rated IP20 and uses a Type 1 enclosure configuration. It is designed as a 600 mm deep MCC-style Frame 9 drive.
Q7: Does this model include dynamic braking?
A: The catalog configuration specifies no internal dynamic-braking option. If braking performance is required by the application, the braking arrangement should be evaluated separately.
Q8: What operator interface is supplied with this version?
A: The JN2 configuration includes an Enhanced LCD, full-numeric, handheld/local HIM. This provides a local interface for drive setup, monitoring, and operator access.
