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
.
• Tripping by activating the bits STO or SS1 via the safety bus.
• In special operation (
) the standard stop can be avoided by confirming it with the enable
switch (
).
• Emergency stop
• Tripping by a safe input with the parameterised function
.
• Tripping by activating the bit SSE via the safety bus.
•
can be set as the function to be executed via the parameter "SSE: Emergency stop
function".
• In special operation (
) the emergency stop cannot be avoided.
• Error stop
• Tripping as response to an error.
• In special operation (
) the error stop cannot be avoided.

Prioritisation
Stop functions with priority influence the process of already started subordinated functions.
1.
• 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.
• 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.
