No.
Note:
The acceptance test must be individually conducted for each configured control.
The control can be realized via terminals or via PROFIsafe.
1. Initial state
Drive in "Ready" state (p0010 = 0)
•
STO function enabled (onboard terminals CU and MM/PROFIsafe)
•
Enable SS1 function (p9652 > 0, p9852 > 0)
•
No Safety faults and alarms (r0945, r2122, r2132)
•
r9772.22 = r9872.22 = 0 (SS1 deselection via terminal - Control Unit/Motor Module, via
•
PROFIsafe)
r9772.23 = r9872.23 = 0 (SS1 deselection via PROFIsafe - Control Unit/Motor Module, via
•
PROFIsafe)
r9772.0 = r9772.1 = 0 (STO deselected and inactive – CU, via terminals)
•
r9872.0 = r9872.1 = 0 (STO deselected and inactive – MM, via terminals)
•
r9773.0 = r9773.1 = 0 (STO deselected and inactive – drive, via terminals)
•
r9720.1 = 0 (SS1 selected)
•
r9722.1 = 0 (SS1 selected)
•
r9772.2 = r9872.2 = 0 (SS1 not requested – CU and MM)
2. •
When terminals are grouped for "Safe Torque Off":
3. •
r9774.0 = r9774.1 = 0 (STO deselected and inactive - group)
4. Run the drive
5. Check whether the correct drive is operational
Select SS1 when the run command is issued
Check the following:
The drive is braked along the OFF3 ramp (p1135)
•
Before the SS1 delay time (p9652, p9852) expires, the following applies:
r9772.22 = r9872.22 = 1 (STO selection via terminal - Control Unit/Motor Module, via

PROFIsafe)
r9772.23 = r9872.23 = 1 (STO selection via PROFIsafe - Control Unit/Motor Module, via
•
PROFIsafe)
r9772.0 = r9772.1 = 0 (STO deselected and inactive – CU, via terminals)
•
r9872.0 = r9872.1 = 0 (STO deselected and inactive – MM, via terminals)
•
r9772.2 = r9872.2 = 1 (SS1 active – CU and MM, via terminals)
•
r9773.0 = r9773.1 = 0 (STO deselected and inactive – drive, via terminals)
•
r9773.2 = 1 (SS1 active – drive, via terminals)
