5.3 Disabling the PROFIBUS Sign-of-Life Monitoring
Principle
The PROFIBUS connection between the technology CPU and the SINAMICS S120 is
monitored using a sign of life. The sign-of-life monitoring is selected automatically when the
axis is created and should always be active during operation.
For diagnostic purposes, the sign-of-life monitoring can be disabled temporarily during the
commissioning.
The parameters for the sign-of-life monitoring can be selected/deselected on the Axis
technology object with "Expert list > Configuration data" or on the drive using the "p0925"
parameter.
To do this, mark "Axis_1" and select the Expert list menu command in the context menu.
Switch in the expert list to the "Configuration data" tab and to the
"\TypeOfAxis\NumberOfEncoders\Encoder_1\DriverInfo\lifeSignCheck" dialog there.
Alternatively, you can also select the Expert list > p0925 menu command in the "Drive_1"
context menu.
