The STO safety function integrated into the product can be used to implement an "EMERGENCY STOP" (IEC 60204-1) for category 0 stops.
With an additional, approved EMERGENCY STOP module, it is also possible to implement category 1 stops.
STO function
The STO safety function is triggered via 2 redundant inputs. The circuits of the two inputs must be separate so that there are always two
channels. The switching process must be simultaneous for both inputs (offset < 1 s).
The power stage is disabled and an error message is generated. The motor can no longer generate torque and coasts down without braking.
A restart is possible after resetting the error message with a "Fault Reset".
The power stage is disabled and an error message is generated if only one of the two inputs is switched off or if the time offset is too great.
This error message can only be reset by switching off the product.
Diagram without Preventa Safety Module
Connection diagrams conforming to standards EN 954-1 category 2 and IEC/EN 61508 capacity SIL1, stopping category 0 in accordance
with standard IEC/EN 60204-1.
The connection diagram below is suitable for use with machines with a short freewheel stop time (machines with low inertia or high resistive
torque).
When the emergency stop is activated, the drive power supply is cut immediately and the motor stops in freewheel, according to category 0
of standard IEC/EN 60204-1.
