(from SM301 V1.1)
•
(from SM301 V1.3)
3.9.1
Safe stop
General information
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, or SS2*.
• Tripping by activating the bits STO, SS1 or SS2* 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.
