Safe Stop 1 Without Encoder (Time And Speed Controlled) - Siemens SINAMICS G130 Manual

Safety Integrated Extended Functions
6.4 Safe Stop 1 (SS1)
Responses
Speed limit violated (SBR):
● STOP A
● Safety message C01706/C30706
System errors:
1. STOP F with subsequent STOP B, followed by STOP A
2. Safety message C01711/C30711
Status for "Safe Stop 1"
The status of the "Safe Stop 1" function is displayed using the following parameters:
● r9722.1 CO/BO: SI Motion status signals, SS1 active
● r9722.0 CO/BO: SI Motion status signals, STO active (power removed)
6.4.2

Safe Stop 1 without encoder (time and speed controlled)

Note
Use of "Safe Stop 1" (SS1) without encoder s only possible for asynchronous motors.
Functional features of "Safe Stop 1" without encoder
The motor is immediately braked with the OFF3 ramp as soon as "Safe Stop 1" is triggered.
Monitoring is activated once the delay time in p9582/p9382 has elapsed. Monitoring ensures
that the motor does not exceed the set braking ramp during the braking process. As soon as
the speed drops below the breaking speed (p9560/p9360), safe monitoring of the brake
ramp is deactivated and safe pulse suppression (STO) is activated. If the set brake ramp is
violated (exceeded), messages C01706 and C30706 are output and the drive is stopped with
STO (STOP A).
