1FK2 & SINAMICS S210 – The servo drive system for medium-complexity higher dynamic motion control applications

SINAMICS S210 SIMOTICS S-1FK2 servo drive system

Working in combination with the SINAMICS S210 drives, SIMOTICS 1FK2 servo motors allows for highly dynamic movement of minimal loads as well as ultra-precise movement of medium and higher loads. The system offers 5 power classes ranging from 50 to 750 watts (0.07 to 1 Hp). The drive features integrated safety functions and streamlined engineering.

Connected to the higher-level PLC over PROFINET industrial Ethernet, the drive allows simpler commissioning using a web server as well as one-button tuning.

SIMOTICS S-1FK2 Servomotors – Features / Technical information

Increased performance

  • Low moment of inertia facilitates significantly higher cycle rates

  • High-resolution encoder with fast sampling for stable and precise closed-loop control

  • Automatic drive parameterization using the electronic motor nameplate

Optimized connection system using OCC (one cable connection)

  • Only one cable required to connect the motor and servo drive (to transfer energy, connect an encoder and control the brake) - reduces installation/replacement time and saves space

  • 22-bit safety-rated encoders

  • Compact with a small rotatable connector for simple installation and mounting – even when space is restricted

  • Thin OCC for small bending radii ensures simple cable installation

SINAMICS S210 servo drive – Features / Technical information

Easy commissioning using a web server and one-button tuning

Reduced engineering time with SIMATIC S7-1500 / T-CPU PLCs

Integrated safety functions

Integrated web server allows the drive to be commissioned and fully diagnosed without additional software

Motion control functions, e.g. positioning or cams, facilitate engineering perfectly coordinated with the drive

As standard: STO (Safe Torque Off), SS1 (Safe Stop 1)

The PLC can directly access the web server in the drive via PROFINET

Tested application example available for connecting the servo drive system to a SIMATIC control

> Available at www.siemens.com/sinamics-applications

Available soon: SBC (Safe Brake Control), SS2 (Safe Stop 2), SOS (Safe Operating Stop), SLS (Safely Limited Speed), SSM (Safe Speed Monitor), SDI (Safe Direction), SBT (Safe Brake Test)

One-button tuning, with selectable dynamic levels to adapt to the required machine dynamics, allows the controller settings to be easily optimized

Control the integrated safety functions via PROFIsafe, STO also via terminal
