Product Overview

SIEMENS 1FK7060-5AH71-1FH0 Replacement for SIMOTICS S 1FK7: Seamless Transition & Legacy System Upgrade

When your existing SIMOTICS S 1FK7 Series servo drive system reaches end-of-life or a critical component fails on the production floor, unplanned downtime becomes your most expensive problem. The SIEMENS 1FK7060-5AH71-1FH0 is a compact, high-performance AC servo motor from the SIMOTICS S 1FK7 family, engineered for precision motion control in demanding industrial automation environments. Whether you are replacing a failed unit, upgrading from an older 1FK6 or 1FT6 series motor, or migrating a legacy SIMATIC S5 or early SIMATIC S7-300 motion axis to a modern SINAMICS S120 drive architecture, this motor delivers the dimensional compatibility, encoder interface, and power class continuity your retrofit project demands.

The 1FK7060-5AH71-1FH0 operates at a rated speed of 3000 rpm with a stall torque of 6.0 Nm, housed in a 60 mm flange frame. Its natural-cooled design eliminates the need for external cooling infrastructure, reducing cabinet complexity and maintenance overhead. The integrated DRIVE-CLiQ encoder interface enables direct plug-and-play commissioning with SINAMICS S120 Booksize or Chassis drive modules, dramatically reducing the engineering time required during a system migration compared to legacy resolver-based motors that required separate SMC30 Sensor Module Cabinet-Mounted units.

For facilities currently operating SIMATIC S7-300 or S7-400 controllers with FM 357 or FM 354 positioning modules driving older 1FT5 or 1FK6 motors through SIMODRIVE 611 drive systems, the migration path to 1FK7060-5AH71-1FH0 paired with a SINAMICS S120 CU320-2 Control Unit is well-documented and field-proven. The motor’s power connector and signal connector pinout follows the standard SIMOTICS S 1FK7 wiring convention, meaning existing motor cables with the appropriate Connector Kit can often be reused, minimizing rewiring labor on the machine side.

In retrofit projects where the control cabinet houses a SINAMICS S120 Motor Module in booksize format, the 1FK7060-5AH71-1FH0 connects directly via a pre-assembled MOTION-CONNECT 500 or MOTION-CONNECT 800PLUS power cable and a DRIVE-CLiQ signal cable, both available in standard lengths. The DRIVE-CLiQ topology allows the CU320-2 to automatically identify the motor parameters at startup, eliminating manual encoder configuration steps that were mandatory with older SMC10 or SMC20 sensor modules used in SIMODRIVE 611 installations.

For machine builders and end users migrating from SIMATIC S7-300 with PROFIBUS DP motion control to SIMATIC S7-1500 with PROFINET IRT, the 1FK7060-5AH71-1FH0 integrated into a SINAMICS S120 axis group supports both communication protocols during a phased migration, allowing the new servo axis to coexist with legacy PROFIBUS peripherals on the same network segment. This is particularly valuable in multi-axis gantry systems or coordinated conveyor lines where a full simultaneous cutover is operationally impractical.

Physical installation compatibility is a key consideration in any servo motor replacement. The 1FK7060-5AH71-1FH0 uses a standard IEC 60072 60 mm flange with a 14 mm shaft diameter, matching the mounting footprint of most 1FK6040 and 1FK6060 predecessors. In applications where the original motor was mounted with a planetary gearbox such as a SIMOGEAR or third-party inline reducer, the shaft and flange dimensions should be verified against the gearbox input specification before installation. The motor’s overall length must also be checked against the available cabinet depth or machine enclosure clearance, particularly in compact servo press or injection molding machine applications.

From a power supply perspective, the 1FK7060-5AH71-1FH0 is designed for operation with a SINAMICS S120 Active Line Module or Basic Line Module supplying a DC link voltage in the 540–600 V range. Facilities upgrading from SIMODRIVE 611 systems with a separate infeed module will need to verify DC bus compatibility or install a new line module as part of the migration scope. In multi-axis installations, the shared DC bus architecture of SINAMICS S120 allows regenerative energy from decelerating axes to be redistributed to accelerating axes, improving overall energy efficiency compared to the older SIMODRIVE 611 individual axis topology.

Seamless Upgrade Solutions

A successful migration to the 1FK7060-5AH71-1FH0 rarely involves the servo motor alone. In most field retrofit scenarios, the motor replacement is part of a broader drive system modernization. The SINAMICS S120 CU320-2 DP or CU320-2 PN Control Unit serves as the central motion controller, replacing the legacy NCU or FM positioning module. Paired with a SINAMICS S120 Single Motor Module 9 A booksize, the 1FK7060-5AH71-1FH0 forms a complete single-axis servo drive package suitable for direct integration into an existing SIMATIC S7-1500 or S7-300 PLC architecture via PROFINET or PROFIBUS.

For the power supply side, a SINAMICS S120 Basic Line Module 10 kW provides the rectified DC bus voltage required by the Motor Module. In installations where regenerative braking energy recovery is a priority, an Active Line Module with Active Interface Module offers full four-quadrant operation and harmonic mitigation, meeting modern grid compliance requirements that older SIMODRIVE 611 infeed modules could not satisfy.

On the signal and feedback side, a MOTION-CONNECT 800PLUS signal cable connects the motor’s DRIVE-CLiQ port directly to the Control Unit or Motor Module, eliminating the SMC30 Sensor Module Cabinet-Mounted that was mandatory in legacy resolver-based installations. For applications retaining an older motor with resolver feedback on an adjacent axis, the SMC10 Sensor Module can still be used in a mixed topology, allowing a phased axis-by-axis migration without requiring a full system cutover.

Terminal modules such as the SINAMICS S120 Terminal Module TM31 provide additional digital and analog I/O for machine interlocks, enabling speed override signals, and interfacing with safety relays or a SIMATIC ET 200SP distributed I/O station on the PROFINET network. In cabinet-constrained installations, the compact SINAMICS S120 booksize format allows multiple Motor Modules to share a single Active Line Module on a common DC bus rail, maximizing the use of available panel space compared to the individual axis topology of SIMODRIVE 611.

For programming and commissioning, the SIMATIC STARTER or Startdrive (TIA Portal integrated) software tool automates motor identification and parameter upload via DRIVE-CLiQ at first power-on, significantly reducing the manual parameterization effort compared to legacy SIMODRIVE 611 commissioning with SimoCom U. A standard USB-to-RS232 programming cable or PROFINET direct connection from the engineering laptop to the CU320-2 is all that is required to complete the drive commissioning sequence.

Retrofit Guidance FAQ

Q: Can I reuse my existing motor power cable from the 1FK6060 installation?
A: In many cases, yes. The 1FK7060-5AH71-1FH0 uses the standard SIMOTICS S 1FK7 power connector (size 1). If your existing MOTION-CONNECT cable has the correct connector kit for the 1FK7 series on the motor end and is rated for the current class, it can be reused. Verify cable cross-section and shielding continuity before reuse.

Q: Do I need to update my PLC program when replacing the motor?
A: If the drive parameters (rated torque, speed, encoder resolution) are matched correctly in the SINAMICS S120 drive during commissioning, the PLC motion program typically requires no modification. The axis object in SIMATIC S7-1500 Motion Control or the FM 357 positioning module sees the same axis interface regardless of the physical motor model.

Q: Is PROFIBUS DP still supported with the SINAMICS S120 and 1FK7060-5AH71-1FH0?
A: Yes. The CU320-2 DP variant supports PROFIBUS DP natively, allowing the 1FK7060-5AH71-1FH0 axis to be integrated into an existing SIMATIC S7-300 or S7-400 PROFIBUS network without any PLC hardware changes. PROFINET IRT is available with the CU320-2 PN variant for new installations.

Q: What is the physical space requirement compared to the 1FK6060?
A: The 1FK7060-5AH71-1FH0 has a slightly shorter overall length than the equivalent 1FK6060 variant in most configurations, which is advantageous in space-constrained machine enclosures. The 60 mm flange and 14 mm shaft are dimensionally identical, so the mounting interface and coupling require no modification.

Q: How long does commissioning take after physical installation?
A: With DRIVE-CLiQ and Startdrive (TIA Portal), motor identification and basic axis commissioning typically takes 30–60 minutes for a single axis. The DRIVE-CLiQ interface automatically uploads motor nameplate data to the Control Unit, eliminating manual parameter entry. Safety function configuration (STO, SS1) adds additional time if required.

Q: Can this motor be used as a direct spare part replacement without changing the drive?
A: If the existing drive is a SINAMICS S120 with DRIVE-CLiQ capability, yes — the 1FK7060-5AH71-1FH0 is a plug-and-play replacement. If the existing drive is a SIMODRIVE 611 with resolver interface, a drive upgrade to SINAMICS S120 is required, or an SMC10 Sensor Module must be added to adapt the DRIVE-CLiQ encoder signal.
