3.5 Safety functions

3.5.1 Stop functions

The stop functions are divided according to the tripping reason:

• Standard stop (simple stop)

• Tripping by a safe input with the parameterised functions STO

, SS1.

• Tripping by activating the bits STO or SS1 via the safety bus.

• In special operation (OMS

) the standard stop can be avoided by confirming it with the enable

switch (ES

).

•Emergency stop

• Tripping by a safe input with the parameterised function SSE

.

• Tripping by activating the bit SSE via the safety bus.

• STO

or SS1 can be set as the function to be executed via the parameter "SSE: Emergency stop

function".

• In special operation (OMS

) the emergency stop cannot be avoided.

• Error stop

• Tripping as response to an error.

• In special operation (OMS

) the error stop cannot be avoided.

Short overview of "Safety functions  Safe stop" parameter group:

3.5.1.1 Prioritisation

Stop functions with priority influence the process of already started subordinated functions.

1. Safe torque off (STO)

• The STO function has the highest priority and thus takes priority over all other functions.

Functions already started (e.g. SS1) are cancelled and the drive is switched off.

2. Safe stop 1 (SS1)

• Considering the stop time for SS1, the drive is switched to torque-free operation.

3. Monitoring functions

• The monitoring functions have the same priorities. They can be executed at the same time.
