Safe Brake Ramp (SBR)

The Safe Brake Ramp (SBR) function provides a safe method for monitoring the brake ramp.
The Safe Brake Ramp function is used to monitor braking when using the "SS1 without
encoder" and "SLS without encoder" functions.
Features
The motor is immediately decelerated along the OFF3 ramp as soon as SS1 or SLS is
triggered (if setpoint speed limitation is used). Monitoring of the brake ramp is activated once
the delay time in p9582/p9382 has elapsed. Monitoring ensures that the motor does not
exceed the set brake ramp (SBR) when braking. Deactivation of the safe monitoring of the
brake ramp occurs
● for SS1:
● for SLS:
Additional specific functions (e.g. STO, new SLS speed limit, etc.) are activated at this point,
depending on the Safety Integrated function used.

as soon as the speed drops below the shutdown speed (p9560/p9360).
– as soon as the set brake ramp has reached the new SLS level
or
– as soon as the actual speed has fallen below the newly selected SLS level and has
remained there for the time parameterized in p9582/p9382.
