SSM safety sub-function with MOVISAFE^® CS..A

The SSM function provides a safe output signal on the safe process data to indicate whether the speed is below a specified limit value.

A speed filter can be activated for each instance of the SSM function. The speed filter integrates the speeds exceeding the speed limit along the track. If the track is longer than the parameterized track, feedback is provided by the corresponding status message.

Use the Effective direction parameter to determine in which direction the SSM function should be effective (positive, negative, or both directions) for each SSM function.

Do not exceed the maximum speed while moving against the effective direction.

If the SSM function is activated, the speed hysteresis must be lower than the limit speed.
