8.A268.F8AN.A222 Ethernet/IP Encoder with Ø30 mm AX Adapter

For 8.A268.F8AN.A222, EncoderWorks can provide a custom compatible replacement solution for large-shaft Ethernet/IP absolute encoder systems where the key checks are ø30 mm H7 bore fit, torque-arm-side locking-ring access, 150 mm torque-arm preload, Ethernet/IP device configuration, and three-M12 connector wiring. This model should not be treated like the Modbus AX version, because both the fieldbus interface and the AX mechanical arrangement are different. Typical production lead time: 15 working days.

This configuration combines a Kübler AX hollow-shaft adapter with a Sendix F5868 absolute multiturn encoder. The AX section provides the ø30 mm hollow-shaft bore, locking ring on the torque-arm side, and 150 mm torque arm, while the encoder body provides Ethernet/IP absolute position feedback through three radial M12 connectors. Replacement work should focus on shaft fit, clamp torque, torque-arm alignment, IP address or device configuration, position scaling, preset behavior, network diagnostics, and shield grounding.

System Limits

The first system limit is AX mechanical installation. The ø30 mm shaft must match the H7 adapter bore without forcing the clamp, and the locking ring must be accessible from the torque-arm side. A 150 mm torque arm gives more installation reach, but it also makes preload, bracket stiffness, and housing movement more important.

The second limit is Ethernet/IP commissioning. The controller must preserve the expected device configuration, IP address, assembly data, scaling, preset value, counting direction, and diagnostic behavior. If the encoder is online but the data format or scaling differs, the PLC may receive stable position data with the wrong mechanical value.

The third limit is the AX operating envelope. The adapter is rated IP64 and has temperature-dependent speed limits. High shaft speed, high ambient temperature, or a loaded torque arm can become the practical failure boundary before the Ethernet/IP communication becomes unstable.

Wiring & Installation

Before replacement, record the Ethernet/IP device settings, IP address, scaling parameters, preset value, counting direction, assembly configuration, and diagnostic behavior from the controller project. Also record the three radial M12 connector assignments for Ethernet ports, power supply, and shield connection.

During installation, confirm the ø30 mm H7 shaft fit, keep the locking ring on the torque-arm side, and align the 150 mm torque arm without preload. Route Ethernet and power cables away from inverter output wiring, maintain shield continuity through the M12 connectors, and avoid ground loops between the encoder housing, machine frame, and cabinet earth. After startup, verify network status, actual position value, direction, preset response, torque-arm movement, and repeatability over several machine cycles.

Custom Compatible Solution

EncoderWorks can configure the replacement around the installed shaft and Ethernet/IP system:

• Match the AX ø30 mm hollow-shaft adapter, torque-arm-side locking ring, 150 mm torque arm, and mounting envelope
• Preserve Sendix F5868 Ethernet/IP absolute position feedback, device configuration, scaling, preset, and direction behavior
• Adapt the three radial M12 connector layout, 10–30 VDC supply range, Ethernet wiring, and shield grounding
• Review clamp torque, shaft fit, torque-arm preload, IP64 installation limits, and temperature-speed operating margin
