Brake ramp monitoring
The motor is immediately decelerated along the OFF3 ramp as soon as SS1 is triggered.
Monitoring is activated once the delay time in p9582/p9382 has elapsed. The drive is
monitored during braking to ensure the set brake ramp is adhered to. As soon as the speed
drops below the shutdown speed (p9560/p9360), safe monitoring of the brake ramp is
deactivated and safe pulse suppression (STO) is activated. If the set brake ramp (SBR) is
violated (exceeded), messages C01706 and C30706 are output and the drive is stopped with
STO (STOP A).

Figure 8-4 Sequence for "Safe Stop 1" without encoder (p9506/p9306 = 1)
Functional feature of Safe Stop 1 without encoder
Selection and monitoring of the brake ramp (SBR) or the acceleration (SAM) are
implemented in two channels, however braking at the OFF3 ramp is only through one
channel.
