SINAMICS S110 single machine axes, available from CNC Design , can be positioned precisely for applications in machinery and plant construction. SINAMICS S110 single machine axes integrate the required positioning functions and can control both synchronous as well as induction servomotors. These machine axes support a variety of encoder types. An analogue +/-10 V setpoint interface as well as various field bus interfaces are available to connect a SINAMICS S110 drive unit to a higher-level control.

SINAMICS S110 drives can be used in the following applications:

  • Handling equipment
  • Feed and withdrawal equipment
  • Stacking units
  • Automatic assembly machines
  • Laboratory automation systems
  • Tool changing mechanisms
  • Adjuster and actuator axes
  • Tracking equipment such as solar panels
  • Medical technology and health systems such as patient beds

SINAMICS S110 frequency converters feature integrated safety functions. Safety guidelines and directives can be implemented without requiring any additional equipment and resources. As the safety functions are integrated, they respond in critical situations to avoid damage to man and machine. Safety functions are either controlled using safety-relevant onboard input terminals or through PROFIBUS using the PROFIsafe profile.

Following are the integrated safety functions:

  • Safe Torque Off (STO)
  • Safe Operating Stop (SLS)
  • Safe Stop, Cat. 1 (SS1)
  • Safe Stop, Cat. 2 (SS2)
  • Safely Limited Speed (SLS)
  • Safe Speed Monitor (SSM)
  • Safe Brake Control (SBC)

The SINAMICS S110 positioning drive is similar to the SINAMICS S120 motion control drive system. It is possible to migrate to SINAMICS S120 if a drive solution, equipped with SINAMICS S110 requires more performance.

A power module, PM340 hardware is used for the SINAMICS S110 positioning drive and for S120 AC drives. The SINAMICS S110 positioning drive is mounted with a control unit. An optional filter can also be integrated. The power modules are available in a range of power ratings from 0.12kW to 90kW and in low voltage (1-ph. 230V) as well as medium voltage (3-ph. 380 to 480V) versions.

The SINAMICS S110 single-axis drive can control linear axes similar to rotary axes in-line with application requirements. Axes can be positioned to absolute target points or moved through relative distances. An optional following error monitoring function that can be activated immediately issues an alarm if irregularities occur while traversing. The zero speed monitoring at the end positions has an alarm function. When it is required, jerk limiting can ensure that the axis starts and stops smoothly. As a consequence, sensitive products or containers filled with liquid can be moved but at the same time with low associated stress.

The ‘MDI’ mode is a simple way of positioning using SINAMICS S110. The positioning parameters (velocity, target position/travel distance, optionally also acceleration rates) can be entered from the higher-level control, and are activated by the start command. If required, individual parameters for positioning travel can be modified as the axis moves.

Traversing profiles can be implemented in the ‘traversing blocks’ mode. Up to 16 position or traversing distances can be saved in the drive together with the corresponding velocity and acceleration parameters. These traversing blocks can be executed either sequentially or according to additional criteria.

Goods arriving on a conveyor belt can be brought into a precise position using the jog mode. Epos can be used to clamp workpieces using the travel to endstop function.

SINAMICS S110 is suitable as a drive converter for standard positioning tasks. This can involve machinery axes with a high dynamic performance, which define the primary process of a machine or plant, as well as also actuator axes that are less critical from a time perspective. SINAMICS S110 positions synchronous and induction motors with power ratings of up to 90kW.

SINAMICS S110 is open when it comes to the source of the motor that is being used. Both 1FK7/1FT7 synchronous servomotors as well as the smooth-running 1PH7 induction motors have electronic type plates and a digital DRIVE-CLiQ interface that permits drive systems to be quickly commissioned.

The SINAMICS S110 positioning drive is available with a PROFIBUS interface and supports standard protocols such as PROFIdrive and PROFIsafe for connection to a higher-level control system. The SINAMICS S110 positioning drive can also be connected to a higher-level control through the CANopen interface. The SINAMICS S110 positioning drive can be optimally integrated into the SIMATIC automation system through PROFIBUS.
