Baumuller Error No. 200

 SERCOS slave has no cyclical communication

The data between the master/control and the slave (drive controller) is cyclically swapped via the SERCOS drive ring. The function of this communication is monitored via a “sign-of-life” exchange. This error is generated if this sign-of-life is missing for more than a timeout period. 
Note: The monitoring is not activated by the master / controls until after the first activation of the sign-of-life exchange.
The drive is braked with a secured hold and is independently switched off on coming to a standstill. (If the parameter ID 557 “SH setpoint acc.[Ax]” is zero or if the drive is not on the set safety braking ramp after 1.5-times the time, it is also independently switched off.)

Source and Remedy 
Control function (temporarily) faulty Reinstate the control function (restart, switch back on, etc.) 
Function of the drive master faulty (e.g. SDC / MDS) Reinstate the function of the drive master (restart, switch back on, etc.) 
Communication between the controls and the master is physically interrupted. Reinstate the connection 
Only for SDC: The active bit (bit index 0) of the corresponding drive control parameter has been deleted The control – drive connection has been logically disconnected. The drive-control parameter must be reinstated. 
Communication between the master and drive is physically interrupted. Reinstate the connection 
The phase run-up in the drive ring has be re-triggered. Wait until the drive ring is ready for service again (SERCOS phase 4 and reached synchronicity). 
The successor in the drive ring has switched to the SERCOS redundancy input. The slave telegrams sent out therefore no longer reach the master. After correcting the error, the ring has to be restarted (see documentation or BAUDIS web tool on SERCOS restart). 
The SERCOS hardware of the drive slave is faulty. Replace the controller cassette.
