Configured for frequency-controlled motor induction management in 480 VAC 3-phase electrical networks, the Allen-Bradley 20F1AND125JA0NNNNN (PowerFlex 753 AC Drive) provides direct physical electrical execution for variable speed applications.

Model Suffix Breakdown

The 20F1AND125JA0NNNNN identifies a Frame 6 power chassis rated for 125 Amps output current. The designation specifies an AC input stage with integrated precharge circuitry, the absence of a dynamic braking transistor, and a factory-filtered EMC configuration with the common-mode (CM) jumper installed to address line-side conducted emissions.

Hardware Specifications

Industrial Control Deterministic Network Attributes

The PowerFlex 753 architecture supports high-speed data exchange via EtherNet/IP or Profinet deterministic networks, ensuring synchronized motor control across multi-axis configurations. The module facilitates I/O density scaling through internal option slots, while firmware flash compatibility maintains alignment with existing control protocols. This hardware utilizes high-speed internal bus communication to ensure minimal latency in velocity command processing and torque regulation.

Ordering Info

• 1 x 20F1AND125JA0NNNNN AC Drive

• 1 x Embedded I/O terminal block

• Note: The unit is supplied as a "Blank" configuration without an external Human Interface Module (HIM).

Installation and Field Guidelines

• Mounting: Mount the Frame 6 chassis vertically in an industrial cabinet, ensuring adequate clearance above and below for the forced-air cooling system operation.

• Shielding: Utilize high-frequency shielded cabling for motor leads to minimize radiated electromagnetic interference (EMI).

• Grounding: Bond the drive chassis to the plant protective earth bus. Maintain the factory-installed common-mode (CM) jumper to ensure compliance with EMC filtering standards.

• Environment: Install only within environments free of corrosive gas. Ensure ambient air temperature and humidity remain within defined limits to prevent operational derating.

Frequently Asked Questions

• Q: Is this drive model equipped with a dynamic braking transistor?

  A: No, the 20F1AND125JA0NNNNN model does not include a dynamic braking (DB) transistor; it is intended for applications without regenerative energy requirements.

• Q: Does the drive come with an interface module?

  A: No, this model is supplied with a "Blank" interface (no HIM), requiring an external HIM or configuration software for programming and monitoring.

• Q: What is the maximum motor power rating?

  A: The drive is rated for 100 HP in Normal Duty (ND) applications and 75 HP in Heavy Duty (HD) applications.

• Q: Is the unit suitable for outdoor use?

  A: No, this is an Open Type (IP20/IP00) unit and must be enclosed within an appropriate cabinet to prevent ingress of foreign objects and moisture.

• Q: What is the function of the CM jumper?

  A: The CM jumper provides a reference for the internal EMC filter, which is required for effective common-mode noise suppression on the AC line side.

• Q: Can this drive connect to a common DC bus?

  A: No, the 20F1AND125JA0NNNNN model lacks DC terminals and is restricted to AC input and precharge configurations only.

• Q: How are firmware updates performed?

  A: Firmware is flash-compatible and can be updated via the drive's embedded communication ports using standard configuration software.

• Q: Are the cooling fans field-serviceable?

  A: Yes, the cooling system is designed for service access; refer to the technical manual for replacement part numbers and procedural steps.
