SINAMICS G/S: Speed control of a G110/S110 using S7-1200 (TIA-Portal) with USS®-Protocol (CE-X11)
Two asynchronous motors, each of them connected to the SINAMICS G110 frequency inverter, are to be controlled by an S7-1200 controller (CPU1211C) via the CM1241 (RS485) communication module. Communication between controller and frequency inverter takes place with the aid of the USS protocol. A KTP600 touch panel that is connected to the S7-1200 controller via an Ethernet connection is used for operation and visualization. STEP 7 Basic V10.5 is used as a configuration tool for the control program and the HMI.
The motors are to be operated on speed. A setpoint from 0 to 100% is specified. It is to be possible to change the direction of rotation and to acknowledge drive errors. During runtime it is to be possible to read and change parameters of the frequency inverter via the USS protocol. The actual speed is to be displayed together with the drive status.
For the startup we offer you software examples with test code and test parameters as download. These software examples support you in the first steps and tests of the configuration examples. They enable a quick test of hardware and software interfaces of the products described in the configuration example.
