Acceptance test for Safe Torque Off (STO)
"Safe Torque Off" (STO) function
This test comprises the following steps:
Table 9-10 "Safe Torque Off" (STO) function
No.
Description
Status
Initial state
Drive in "Ready" status (p0010 = 0)
STO function enabled (p9601.0 = 1, p9801.0 = 1)
No safety faults and alarms (r0945, r2122, r2132)
r9772.0 = r9772.1 = 0 (STO de-selected and inactive – CU)
r9872.0 = r9872.1 = 0 (STO de-selected and inactive – MM)
r9773.0 = r9773.1 = 0 (STO de-selected and inactive – drive)
1.
When terminals are grouped for "Safe Torque Off":
r9774.0 = r9774.1 = 0 (STO de-selected and inactive - group)
2.
Run the drive
3.
Ensure that the correct drive is running
4.
Select STO when issuing the traversing command
Note:
The acceptance test must be carried out for each configured control, which may be via terminals, via the TM54F or via
PROFIsafe.
Check the following:
•
The drive coasts to a standstill or is braked and stopped by the mechanical brake (if
available and configured (p1215, p9602, p9802)).
•
No safety faults and alarms (r0945, r2122, r2132)
•
r9772.0 = r9772.1 = 1 (STO selected and active – CU)
•
r9872.0 = r9872.1 = 1 (STO selected and active – MM)
•
r9773.0 = r9773.1 = 1 (STO selected and active – drive)
5.
•
When terminals are grouped for "Safe torque off":
r9774.0 = r9774.1 = 1 (STO selected and active - group)
6.
Deselect STO
Check the following:
•
No safety faults and alarms (r0945, r2122, r2132)
•
r9772.0 = r9772.1 = 0 (STO de-selected and inactive – CU)
•
r9872.0 = r9872.1 = 0 (STO de-selected and inactive – MM)
•
r9773.0 = r9773.1 = 0 (STO de-selected and inactive – drive)
•
When terminals are grouped for "Safe Torque Off":
r9774.0 = r9774.1 = 0 (STO de-selected and inactive - group)
7.
•
r0046.0 = 1 (drive in "Power-on inhibit" state)
8.
Acknowledge "Power-on inhibit" and run the drive
9.
Ensure that the correct drive is running
