The SSM function warns when the drive is working below a specified speed/feed speed. As long as it remains below the threshold, the function issues a safety signal.
If a speed value drops below a parameterized level, a safety signal is generated. This can be processed, for example, in a safety controller to respond to the event by programming, depending on the situation.
With the SSM function, in the simplest case, a safety door can be unlocked if the speed drops below a non-critical level. Another example is a centrifuge that must be filled only below a configured speed.
Unlike SLS, there is no drive-independent fault reaction when the speed limit is exceeded. The safe feedback can be evaluated in a safety control unit, allowing the user to respond appropriately to the situation.
