Product Overview
The Siemens 1FK7060-5AF71-1DH5 SIMOTICS S Synchronous Servo Motor is a permanent-magnet synchronous servo motor in the SIMOTICS S-1FK7 Compact family. It has a rated torque of 6.0 Nm at a 100 K temperature rise, an optimum operating speed of 3,000 rpm and an optimum operating power of 1.48 kW. Its naturally cooled construction suits industrial machinery requiring controlled rotary movement without a separate motor-cooling circuit.
This variant combines an incremental encoder with 2,048 pulses per revolution and a DRIVE-CLiQ interface. The feedback system supplies rotor-motion information to compatible Siemens drive equipment for closed-loop speed and position control. Its plain shaft accommodates compatible couplings, while the integrated holding brake helps secure a stationary axis when the drive is no longer commanding motion, subject to the brake’s rated holding capacity and the machine’s safety requirements.
The motor uses an IM B5 mounting arrangement, with IM V1 and IM V3 mounting positions also specified. Its power and signal connectors can be rotated through 270°, which helps when routing cables in compact machine enclosures. The protection rating is IP65, with IP67 protection at the drive-end flange. These distinctions matter when assessing exposure to dust, moisture and cleaning conditions around the installed motor.
For maintenance engineers replacing an existing servo motor, the main checks are the complete order number, DRIVE-CLiQ compatibility, encoder configuration, plain-shaft coupling and holding-brake requirements. A motor with the same frame size but a different feedback interface or brake arrangement may not be a direct replacement.

Working Principle
The 1FK7060-5AF71-1DH5 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 current supplied to the motor windings according to the required torque, speed or position.
During operation, the incremental encoder generates feedback signals as the rotor turns. The DRIVE-CLiQ interface allows compatible Siemens drive equipment to communicate with the motor’s feedback arrangement. The drive uses the feedback information to regulate motor current and respond to changes in the commanded motion.
Consider an automated packaging line in which a servo axis moves a feed roller through repeated production cycles. The controller commands the required movement, the drive regulates acceleration and speed, and the encoder supplies feedback for motion control. The resulting positioning performance depends on the complete drive configuration, mechanical transmission, load inertia and motion profile.
Because the encoder is incremental, the system may need to establish a reference position after startup or power loss. The appropriate homing procedure depends on the controller, machine reference sensors and application requirements.
The integrated holding brake serves a different purpose from the motor’s electromagnetic torque production. It helps prevent shaft movement when the motor is stationary, but it should not automatically be treated as a dynamic stopping device. Applications involving suspended loads or safety-critical holding require a brake assessment based on load, stopping requirements and the machine’s safety design.
Role in a SIMOTICS S Servo Control Architecture
The 1FK7060-5AF71-1DH5 acts as the rotary actuator in a closed-loop servo system. The controller issues motion commands, the servo drive regulates motor current, and the encoder returns feedback used to control the axis response. The holding brake supports stationary load retention when operated according to its specified requirements.

Technical FAQs
What distinguishes the 1FK7060-5AF71-1DH5 from the 1DG5 variant?
The 1DH5 configuration includes an integrated holding brake, whereas the 1DG5 configuration does not. Both use incremental encoder feedback and a DRIVE-CLiQ interface. The brake requirement should be evaluated alongside the mechanical load and the machine’s safety design.
Does the motor provide absolute position feedback after a power interruption?
No. This configuration uses incremental encoder feedback rather than an absolute encoder. If the application needs a known axis position after startup, the controller may need to execute a homing or referencing procedure.
What should be checked when connecting this motor to a SINAMICS drive?
Confirm the complete motor order number, electrical ratings, DRIVE-CLiQ connection, encoder configuration and brake-control requirements. The selected drive and its configured hardware must support the specific motor variant.
Can the integrated holding brake stop a moving load during an emergency?
The holding brake is primarily intended to hold the shaft when stationary, within its rated capacity. Whether it is suitable for a particular stopping or safety function depends on the brake specifications and the machine’s safety design; it should not be assumed to replace a dedicated dynamic stopping system.
