20D-STEG-B1 is a feedback option board for PowerFlex 700S drive control. It is designed to interface a compatible Stegmann high-resolution encoder with the drive control system where precise motor-position or speed feedback is required.

The board is an option component rather than a complete drive, so selection depends on the installed PowerFlex 700S control hardware, cassette arrangement and encoder interface.

• Transfers high-resolution Stegmann encoder information into the PowerFlex 700S control architecture.
• Supports feedback-based control applications that require more precise speed or position information than open-loop operation.
• Keeps the specialized encoder interface on a replaceable option board within the drive-control assembly.
• Works as part of the drive feedback chain and therefore depends on correct encoder wiring, shielding and commissioning parameters.
• Provides a defined catalog option for maintaining installed PowerFlex 700S systems using Stegmann feedback.

• Verify the PowerFlex 700S drive type, control phase and expanded-cassette hardware before ordering the option board.
• Match the connected Stegmann encoder interface and cable arrangement to the applicable 700S documentation.
• Record the feedback parameters, motor data and orientation before removing the existing board.
• After installation, validate encoder direction and feedback integrity before enabling normal machine operation.

• PowerFlex 700S motor-control systems using compatible Stegmann high-resolution feedback.
• Maintenance replacement of an installed feedback option with the same catalog identity.
• Closed-loop applications where the drive relies on encoder information for accurate regulation.
• Service work that separates a feedback-board fault from the encoder, cable or main control assembly.
• Lifecycle stocking plans for discontinued PowerFlex 700S option hardware.
