Standards And Approvals - Siemens SIMATIC S7-400 Produktinformation

If a communication problem occurs while the axis is running, the axis continues to run and can no longer be operated from
the PG/PC.
It is only possible to stop the drive again after the communication problem has been solved and the connection has been
restored.
It is therefore essential to ensure before using the function that appropriate measures have been taken (e.g. emergency off
switches, limit switches, protective devices, monitoring settings) in order to avoid endangerment or damage to property and
persons.
WARNING
Safety instructions
If axes are controlled via the commissioning mask of the configuration tool, an interruption of the communication between
PG/PC and S7 CPU can cause the axes to continue turning, but intervention via the commissioning mask is no longer
possible.
It is therefore essential to ensure that there is an option for immediate intervention or shutdown for moving axes via the
commissioning mask of the configuration tool.
All necessary measures must be taken (e.g. emergency off switches, hardware limit switches, protective devices,
monitoring) to avoid endangerment or damage to property and persons.
