2 Parameters
2.2 List of parameters
Description: Sets the velocity limit for the SSM feedback signal to detect standstill (n < nx).
When this limit value is undershot, the signal "SSM feedback signal active" is set.
Caution: The following applies for p9506 = 3:
The "SAM" function is switched out if the selected threshold value is undershot.
Note: SAM: Safe Acceleration Monitor (safe acceleration monitoring)
SSM: Safe Speed Monitor (safety-relevant feedback signal from the velocity monitoring)
Description: Sets the velocity hysteresis for the SSM feedback signal to detect standstill (n < nx).
Dependency: Refer to: C01711
Note: The velocity hysteresis is effective only if the function is enabled (p9501.16 = 1).
The parameter is included in the crosswise data comparison of the two monitoring channels.
SSM: Safe Speed Monitor (safety-relevant feedback signal from the velocity monitoring)
Description: Sets the velocity tolerance for the "SAM" function.
Dependency: Refer to: C01706
Note: SAM: Safe Acceleration Monitor (safe acceleration monitoring)
Description: Sets the delay time for the SLS changeover for the function "safely limited speed" (SLS).
When transitioning from a higher to a lower safely limited velocity/speed stage, within this delay time, the "old"
velocity stage remains active.
Even if SLS is activated from the state "SLS in active", then this delay is still applied.
Note: SLS: Safely Limited Speed
