Product Overview
The Siemens 1FK7060-5AF71-1DG5 SIMOTICS S Synchronous Servo Motor is a permanent-magnet synchronous servo motor in the SIMOTICS S-1FK7 Compact family. It is intended for industrial motion-control systems where the motor must follow commanded speed, torque and position profiles under the control of a compatible servo drive.
This variant combines natural cooling with an incremental sin/cos encoder rated at 2,048 pulses per revolution and a DRIVE-CLiQ interface. The feedback system supplies rotor-motion information to the drive, supporting closed-loop operation in automated machinery. The DRIVE-CLiQ connection is an important selection detail because the motor’s feedback arrangement must match the connected drive and its configuration.
The motor has a plain shaft without an integrated holding brake. This configuration suits mechanical assemblies that use a compatible shaft coupling and do not require a motor-mounted holding brake. If the motor operates a vertical axis or a mechanism that could move under gravity when power is removed, the machine design must account for load retention separately.
Its IM B5 mounting arrangement, rotatable power connector and IP65 protection, with additional IP67 protection at the drive-end flange, are relevant when planning installation and cable routing. For replacement work, the complete order number should be checked rather than selecting a motor solely by its frame size or general 1FK7 family designation.

Working Principle
The 1FK7060-5AF71-1DG5 converts electrical energy into mechanical rotation through the interaction between the stator’s magnetic field and the rotor’s permanent magnets. A compatible servo drive controls the motor current according to the required torque, speed or position.
During operation, the incremental encoder generates sin/cos feedback signals as the rotor turns. The DRIVE-CLiQ interface connects the motor feedback arrangement to compatible Siemens drive equipment, allowing the drive to process motion information and regulate the motor response.
In a production machine, for example, the motor may operate a feed mechanism that advances material in controlled increments. The controller issues the movement command, the drive regulates acceleration and speed, and the encoder feedback helps the system track the resulting motion. Actual positioning performance depends on the complete control system, mechanical transmission and configured feedback processing.
Incremental feedback does not independently establish an absolute machine position after power loss. Where the application requires a known reference position, the controller may need to perform a homing procedure using a reference sensor or another configured method.
The plain shaft transfers torque through a compatible coupling. Correct alignment and suitable coupling selection help avoid excessive shaft loading and vibration. Because the motor has no integrated holding brake, any mechanism that must remain stationary after the drive stops producing torque requires an appropriate load-holding arrangement where necessary.
Role in a SIMOTICS S Servo Control Architecture
The 1FK7060-5AF71-1DG5 serves as the rotary actuator in a closed-loop servo system. The controller determines the required motion, the drive supplies regulated electrical power, and the motor feedback system returns information used to control the axis.

Technical FAQs
What is the purpose of the DRIVE-CLiQ interface on this motor?
DRIVE-CLiQ provides a communication connection between compatible Siemens drive equipment and supported motor components. The selected drive and feedback configuration must support the interface used by this specific motor.
Does the 1FK7060-5AF71-1DG5 use an absolute encoder?
The specified feedback arrangement is an incremental sin/cos encoder with 2,048 pulses per revolution. Applications requiring a known absolute machine position after startup may need a homing or referencing procedure.
What should be checked when replacing another 1FK7 motor with this model?
Compare the complete order number, feedback interface, shaft design, mounting arrangement and holding-brake requirements. In particular, this model’s plain shaft must match the installed coupling, and its DRIVE-CLiQ feedback arrangement must be supported by the connected drive.
Can this motor hold a vertical load when power is removed?
This version has no integrated holding brake. If the mechanism could move under gravity or external force after the motor is de-energized, an appropriately selected external holding mechanism may be required.
