⚙️ Main technical features ⚙️
1. Permanent magnet synchronous technology

The 1FT6 motors offer:

high acceleration,
immediate dynamic response,
extremely stable torque control even under demanding conditions.

These characteristics make them ideal for processes with rapid cycles or continuous direction changes.

2. Precision and repeatability

Combined with high-resolution encoders (6FX2001 series), the 1FT6 family ensures:

accurate positioning,
reduced following error,
stability on high-performance axes.

An essential element in CNC systems and robotics.

3. Full integration with SIMODRIVE 611 and SINAMICS S120

Designed to operate natively with Siemens technology, the motors ensure:

optimal regulation,
immediate communication between drive and controller,
higher work-cycle efficiency.

4. Perfect compatibility with SIMOTION

In SIMOTION-based architectures, 1FT6 motors enable:

advanced multi-axis interpolation,
complex synchronisms,
electronic camming,
high-dynamic mechatronic motion control.

A complete and scalable solution for industrial automation at any level.

🏭 Typical applications 🏭

SIMOTICS S 1FT6 motors are used in:

CNC machine tools (linear and rotary axes)
Multi-axis machining centers
High-speed packaging lines
Robotic handling and pick-and-place systems
Fast motion and manipulation systems
Production lines with electronic synchronization

In all these contexts, servo-motor stability directly affects precision, final product quality, and production continuity.

⚠️ Production status and operational criticalities ⚠️

Many 1FT6 motors are now:

out of production,
increasingly difficult to source on the market,
part of critical plants that cannot sustain long downtimes.

The most frequent failures include: mechanical vibrations and noise, loss of precision and axis drift, overheating, encoder errors, drive-side instability, and sudden CNC cycle stops.

Criticality increases in older installations or lines operating with continuous production cycles.

♻️ The value of E-Repair services for the Siemens 1FT6 series 🔧

E-Repair performs complete repair and regeneration activities, which include interventions on windings, bearings, wiring, sensors, and worn mechanical components, together with advanced refurbishment procedures such as preventive replacement of critical parts, deep technical cleaning, industrial washing, dynamic balancing, dielectric and insulation tests.

Drive tests are performed using Siemens platforms 👉 SIMODRIVE 611 and SINAMICS S120, in order to verify dynamic behavior, torque, current absorption, and axis stability under real operating conditions.

As for feedback systems, E-Repair handles Siemens 6FX2001 encoders, carrying out cleaning, calibration, restoration, or replacement when necessary.

When available, E-Repair can also supply pre-refurbished ready-to-install motors, significantly reducing plant downtime.

Finally, the company integrates the management of 1FT6 motors within its scheduled maintenance programs, supporting customers through the 👉 MAAS (Maintenance as a Service) model and contributing to waste reduction, energy efficiency, and production continuity.

🧩 Conclusion 🧩

Thanks to their robust construction, precise control, and compatibility with major Siemens platforms, the Siemens SIMOTICS S 1FT6 motors continue to deliver reliable performance even on older industrial equipment.

Through E-Repair’s services, it is possible to extend the lifecycle of the motor, reduce production downtime, and ensure operational continuity while adhering to the principles of circular economy and waste reduction.
