A discontinued 400 V three-phase PowerFlex 700 AC drive rated at 205 A output for industrial motor control.

System role

Rebuilt from individual evidence

Documented facts

Evidence limits

The Rockwell Automation product page identifies 20BC205A3ANNANC1 as a PowerFlex 700 AC drive.

The manufacturer lists 400 V three-phase input, 205 A output, 110 kW normal-duty and 90 kW heavy-duty ratings, IP20 enclosure and encoder feedback.

This AC drive converts three-phase power into variable-frequency output to control an industrial motor.

Unknown: installation-specific compatibility, firmware, wiring and unit condition.

System role

This section explains what the product does and where it acts in the surrounding system.

Function
This AC drive converts three-phase power into variable-frequency output to control an industrial motor.
System position
It sits between upstream control or power and the downstream machine or network within the industrial motor power train.
Upstream / inputs
It receives three-phase AC power, speed or torque commands and optional encoder feedback.
Downstream / outputs
It sends controlled motor power and drive state to the automation system.
Limitations
Unknown: installation-specific compatibility, firmware, wiring and unit condition.
