Note
When "Safe Stop 1" (SS1) is installed, the function "Safe Acceleration Monitor" (SAM) is
active. For parameterizing the "Safe Acceleration Monitor" (SAM) function
→ see section "Safe Acceleration Monitor (SAM)".
The delay time (SS1 time) is set using parameters p9356 and p9556. The wait time until the
pulses are suppressed can be shortened by defining a shutdown speed in p9360 and p9560.
To enable the drive to decelerate to standstill, the time set in p9356/p9556 must be sufficient
to allow the drive to decelerate to below the shutdown speed in p9360/p9560 along the
OFF3 ramp (p1135).
Note
So that the drive is able to travel down the OFF3 ramp completely and any motor holding
brake present can be applied, the delay time can be set as follows:
• Motor holding brake parameterized: Delay time ≥ p1135 + p1228 + p1217
• Motor holding brake not parameterized: Delay time ≥ p1135 + p1228
When setting a shutdown speed in p9360/p9560, you must be certain that the safety of
personnel or machinery will not be compromised at speeds less than or equal to this speed
or as a result of subsequent coasting caused by the pulse inhibit.
The actual speed tolerance is set using parameters p9348/p9548 (for more information
please see section "Safe Acceleration Monitor (SAM)").
Responses
Speed limit violated (SAM):
● STOP A
● Safety message C01706/C30706
System errors:
1. STOP F with subsequent 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)
