The performance-optimized and easy-to-operate servo drive system

The system is made up of the SIMOTICS S-1FL6 servo motor and the SINAMICS V90 servo drive, which can operate in single- and three-phase networks with power outputs ranging from 0.05 to 7.0 kW. It is readily integrated using Modbus RTU, PROFINET, USS, or PTI. The SINAMICS V90 system focuses on dynamic motion and processing while allowing for the cost-effective implementation of basic motion control tasks.

The best servo drive option for motion control applications is SINAMICS V90.

The servo drive system comprises the SINAMICS V90 servo converter and the SIMOTICS S-1FL6 servo motor. For operation in single-phase and three-phase networks, diverse converter frame sizes and motor shaft heights cover a wide range of applications with the focus on dynamic motion and processing – for example positioning, conveying and winding.


  • One-button tuning and real-time auto-tuning
    The control loop parameters are optimized automatically. One Button Tuning can be used during commissioning of the system


  • Sufficient encoder resolution and high data transfer rates
    Due to fast data transfer and with a resolution of up to 21 bits for the encoder


  • Optimized system performance
    Rapid acceleration and braking, with smooth operation in order to ensure high machine productivity

Choosing your servo drive system step-by-step

We walk you through every step of setting up your servo drive system, from choosing the best converter and servo motor for your needs to connecting the necessary cables and connectors to selecting the ideal controller.

The appropriate servo motor

Choose the right servo motor for the job at hand.

  • Permanent magnet-excited synchronous motors, like the SIMOTICS S-1FL6 servo motor, operate without external cooling; their surface dissipates heat.
  • Quick-release connectors enable quick and easy motor installation.
  • Combining these motors with SINAMICS V90 frequency converters creates a high-functionality servo system.
  • The motors offer a threefold overload capability, enhancing their performance and reliability.

The optimum converter

Find the optimum converter for your application

  • The SINAMICS V90 servo drive system provides plug-and-play commissioning, optimized servo performance, and quick integration into a SIMATIC PLC control system.
  • It offers a high degree of reliability in operation.
  • Combining the SINAMICS V90 servo drive with the SIMOTICS S-1FL6 servo motor forms an integrated drive system.
  • This integrated system can be easily connected via PTI, PROFINET, USS, or Modbus RTU interfaces.

The suitable cables & connectors

  • Power cable according to length and cross-section (orange)
  • Encoder cable according to length and encoder type (green)
  • Brake cable for selected motor holding brake according to length (black)
  • Setpoint signal for connection of the drive to the PLC (gray)
  • Connectors can also be ordered individually

The right controllers

Find the right controller for your application

  • SIMATIC S7-1200
    Automation solutions must be compact, scalable, and flexible. The S7-1200 Basic Controller is available in standard and fail-safe design. The SIMATIC S7-1200 can be perfectly adapted to suit your individual requirements with plug-in signal modules and communication modules.
  • SIMATIC S7-1500 inkl. T-CPU
    Advanced Controllers automate complete production plants as well as applications with extremely high demands on performance, flexibility and connectivity. In conjunction with the SIMATIC S7-1500 T-CPU, the SINAMICS V90 servo drive system with PROFINET provides an optimally harmonized motion control solution in the TIA Portal.
