LinMot User OvervieWordw The LinUDP protocol is an easy way for communication with a LinMot servo drive over Ethernet. There are no checks done to make sure if the messages have reached their destination and if they are correctly received. When communicating via LinUDP, the drive has no active function, it only responds to requests with the appropriate answers.
In LinUDP data are the data which we want to transfer. The construction of this data part always is the same. The only difference are the source and destination, they are switched. ® NTI AG / LinMot www.LinMot.com Page 5/19...
When a definition bit is not set, the data part would not be transferred. When all bits of the request definition are set, then the LinUDP data looks like it is shown in the following table. Each field represents one byte. ® NTI AG / LinMot www.LinMot.com Page 6/19...
The LinUDP servo drives have an additional parameter tree branch, which can be configured with the distributed LinMot-Talk software. With these parameters, the LinUDP behaviour can be defined. The LinMot-Talk software can be downloaded from under the section download, software & manuals.
Also restart, start and stop of the drive can be initiated. Of course the parameter channel module works independently from the MC command interface. For this reason, changing a parameter and sending a motion ® NTI AG / LinMot www.LinMot.com Page 8/19...
