SINAMICS S: Positioning of a S110 using S7-1200 (TIA-Portal) with USS®-Protocol (CE-X9)

  • Entry
  • Associated product(s)

A synchronous motor that is connected with a servo drive type SINAMICS S110 is to be positioned via the CM1241 (RS485) communication module of a S7-1200 controller (CPU1214C). Communication between controller and servo drive will be performed by USS protocol. Operation and visualization takes place via a KTP600 touch panel which is to be connected via an Ethernet connection to the S7-1200 controller. STEP 7 Basic V10.5 is used as configuration tool for the control program and the HMI. The servo drive is configured using the STARTER startup tool. The task consists of the following scenarios:

  • moving the motor in jog mode
  • referencing
  • absolute and relative positioning
  • moving the motor according to defined motion profiles

In order to position the motor, setpoint position and the setpoint velocity have to be transferred via the USS protocol to SINAMICS S110, as well as various command bits. SINAMICS S110 will then independently control the positioning or moving of the motor. The SINAMICS S110 will give a feedback to the controller on the various status bits, the actual position the actual velocity and also of error messages.
