PowerFlex 700H | Series B | Three-phase AC drive

The Allen-Bradley 20CE261A0ANNBNG0 PowerFlex 700H is a three-phase AC drive with an adjustable-frequency motor output. Its supply frequency is 47–63 Hz, while the motor-side output frequency range is 0–320 Hz.

The drive carries separate input data for 600 V and 690 V operation. Reading each voltage entry alongside its corresponding current rating keeps the two operating cases clear.

Key Features & Specifications

Adjustable-frequency output: Three-phase AC output over 0–320 Hz.
Two voltage entries: Separate 600 V and 690 V operating data with corresponding normal-duty and heavy-duty input currents.
Motor-control choices: The PowerFlex 700H supports Volts/Hertz and Sensorless Vector control.
Series and firmware identification: Series B hardware and an original firmware marking of 3.001.
Enclosure identification: UL Type 1 / IP21 is the stated drive enclosure marking.

Applications & Use Cases

Pump and fan speed control

Rockwell’s application notes describe Volts/Hertz control for basic centrifugal fan and pump operation. The PowerFlex 700H’s adjustable output gives the control system a variable-frequency motor supply.

Loads requiring a wider speed range

The same application notes describe Sensorless Vector control for applications requiring a wider operating-speed range and torque during breakaway or acceleration. Motor data forms part of that control method; the correct settings depend on the connected motor and load.

Why Choose Allen-Bradley 20CE261A0ANNBNG0?

Selectable control methods: Volts/Hertz and Sensorless Vector address different motor-control requirements.
Separated control hardware: The PowerFlex 700H control module is removable from the power structure.
Parameter and diagnostic tools: The platform provides programming, status and fault information through its supported interfaces.

Compatibility & Integration

Commissioning brings together supply-voltage selection, motor data, ramp settings, speed limits and the start/stop command arrangement. The PowerFlex 700H programming manual organizes these as distinct startup steps.

Network communication is available through optional communication modules in the PowerFlex 700H platform. The network interface is a separate configuration choice from the drive’s motor-control mode.

The 263/210 A values belong to the 690 V input entry; 252/201 A belong to the 600 V input entry. Each pair is ordered normal duty followed by heavy duty. These supply-current values describe input loading rather than a single combined output rating.

Maintenance & Support

The PowerFlex 700H diagnostic menus provide fault information, status information and device-version information. The fault queue helps service personnel examine drive events, while version information identifies the relevant firmware and hardware series.

The platform also provides parameter storage through drive user sets and, with an appropriate HIM, HIM sets. These are useful service records alongside the motor data and application configuration. Hardware work should follow the applicable manufacturer service instructions.
