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/TM54F/PROFIsafe)
•
Enable SBC function (p9602 = 1, p9802 = 1)
•
Brake as in sequence control (p1215 = 1)
•
Mechanical brake is closed
•
No Safety faults and alarms (r0945, r2122)
•
r9772.04 = r9872.04 = 0 (SBC deselection via terminal - 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)
•
r9772.4 = r9872.4 = 0 (SBC not requested – CU and MM)
•
2. Run drive (applied brake is released)
3. Check whether the correct drive is operational
4. Select STO/SS1 during the traversing command.
5. Check the following:
Drive is braked and stopped by the mechanical brake.
•
No Safety faults or alarms (r0945, r2122)
•

•
PROFIsafe)
r9772.0 = r9772.1 = 1 (STO selected and active – CU, via terminals)
•
r9872.0 = r9872.1 = 1 (STO selected and active – MM, via terminals)
•
r9773.0 = r9773.1 = 1 (STO selected and active – drive, via terminals)
•
6. Deselect STO
