SINAMICS DriveSim Basic provides easy-to-use models for PROFIdrive-enabled SINAMICS drives, so you can create a digital twin of your drive.
Load sharing must be implemented whenever two or more motors are mechanically coupled with one another. The "LLoadSharing_Control" function block is used for controlling two mechanically coupled motors with a configurable load sharing.
In most applications, measuring systems are used to determine position actual values; for example a motor encoder. There are also many applications where encoders are not necessary and in fact, in some cases, an encoder is not required at all. The subsequent application example discusses the various options and secondary conditions relating to encoderless positioning.
This application example shows how to configure the positioning function of a SIMATIC S7-1500 and offers a HMI to test the functions.
SIMATIC S7-1500 CPUs support the connection of PROFIdrive-capable drives via PROFINET or PROFIBUS as a speed axis or positioning axis.
SIMATIC S7-1200 can be operated as PROFINET controller as well as PROFIBUS master (with CM 1243-5). A SINAMICS G110M or G120 shall be connected as as PROFINET device or as PROFIBUS slave. The PLC shall have read/write access to the process data and parameters of the drive.
Speed control of a SINAMICS G120 drive via PROFINET or PROFIBUS DP with a SIMATIC S7-300/400.
The SINAMICS G110M implements AS-Interface communication with the control unit CU240M AS-i. The drive can therefore be controlled with AS-i-masters. This application offers control function blocks for Step 7 V5.5 and TIA V13 Sp1 for cyclic and acyclic communication.

Roller conveyors with frequency converters for variable speed are frequently found in conveyor systems. Roller conveyors with a variable speed achieve high conveying velocities with good positioning accuracy.
In the automotive industry, frequency-controlled roll conveyors are used to move skids in the linking conveyor system or between lifters. Roll conveyors operating with a variable speed achieve high conveying velocities with good positioning accuracy. In most cases, this is implemented using a rapid traverse/crawl switchover function.
Task A SIMATIC S7-300/400 is to control a SINAMICS G110M/G120 drive via PROFINET or PROFIBUS DP. ...
