Product Overview
The Siemens 1FK7060-2AF71-1CH0 is a SIMOTICS S-1FK7 compact permanent-magnet synchronous motor for industrial servo-drive applications. It combines controlled rotary motion with absolute position feedback and an integrated holding brake, making it suitable for machine axes that require repeatable positioning and a means of holding the shaft when the motor is not actively driving the load.
The motor operates at a rated speed of 3,000 rpm and delivers a rated torque of 4.7 Nm at a 100 K temperature rise. Its absolute encoder uses a 24-bit single-turn and 12-bit multiturn arrangement with a DRIVE-CLiQ interface. This feedback configuration supports integration with compatible SINAMICS drive systems that use the corresponding encoder interface.
The naturally cooled motor uses an IM B5 flange mounting arrangement and a smooth shaft. Applications can include automated assembly, packaging equipment, machine-feed mechanisms and positioning axes. The selected drive, brake control, encoder connection and mechanical coupling must match the complete motor configuration.

Working Principle
The 1FK7060-2AF71-1CH0 produces rotary torque through the interaction between the stator’s electromagnetic field and the rotor’s permanent magnets. A compatible servo drive supplies controlled three-phase current to regulate torque and speed according to commands from the motion controller.
The AM24DQI absolute encoder measures rotor position and communicates position information through the DRIVE-CLiQ interface. Its single-turn and multiturn data support the drive’s feedback functions, subject to the encoder configuration and drive capabilities. The controller and drive use the configured feedback to manage positioning and motion sequences.
The integrated permanent-magnet brake provides a separate shaft-holding function. It must be released and engaged according to the motor and drive operating requirements. It should not be treated as a routine dynamic stopping device unless the applicable specifications explicitly permit that duty.
The Pt1000 temperature sensor supplies temperature information for compatible monitoring functions. Correct motor identification, feedback setup, brake control and drive parameterization are important for commissioning and maintaining the complete servo axis.
Role in a SINAMICS Servo Control Architecture
The 1FK7060-2AF71-1CH0 acts as the rotary actuator in a closed-loop servo axis. The motion controller generates commands, the SINAMICS drive regulates motor power, and the DRIVE-CLiQ encoder supplies absolute position feedback. The integrated holding brake adds a separate means of retaining the shaft when required by the machine sequence.

Technical FAQs
What encoder is installed in the 1FK7060-2AF71-1CH0?
This model uses an AM24DQI absolute encoder with 24-bit single-turn and 12-bit multiturn data, connected through DRIVE-CLiQ. The drive and cable arrangement must support this specific interface.
What is the purpose of the integrated holding brake?
The permanent-magnet brake holds the shaft when engaged, helping retain the axis in the required stationary condition. Its rated holding torque is 13.0 Nm. Brake selection and operation must account for the actual load and the applicable operating instructions.
Can this motor be replaced by the 1FK7060-2AF71-1CG0?
Do not assume direct interchangeability from the shared motor family and frame alone. Compare the complete order numbers, encoder interface, brake configuration, shaft arrangement and drive compatibility before replacement.
What should be checked if the drive reports an encoder communication fault?
Check the DRIVE-CLiQ cable and connectors, verify that the drive configuration matches the AM24DQI encoder, and inspect the drive’s diagnostic messages. Confirm the motor identification and feedback setup before returning the axis to service.
