Acceptance test for Safe Torque Off (STO)
No.
Description
Status
Note:
The acceptance test must be individually performed for each configured control.
The control can be realized via TM54F, onboard terminals (CU310-2) or via PROFIsafe.
1.
Initial state
• Drive in the "Ready" state (p0010 = 0)
• STO function enabled (onboard terminals/PROFIsafe/TM54F)
• No safety faults and alarms (r0945[0...7], r2122[0...7]); see note "non-critical alarms" at
the beginning of Section "Acceptance test".
• r9772.17 = 0 (STO deselection via terminals - DI CU / EP terminal Motor Module); only
relevant for STO via terminal
• r9772.20 = 0 (STO deselection via PROFIsafe); only relevant for STO via PROFIsafe
• r9773.0 = r9773.1 = 0 (STO deselected and inactive - drive)
• r9774.0 = r9774.1 = 0 (STO deselected and inactive - group); only relevant for grouping
2.
Run the drive
• Check whether the correct drive is operational
Select STO when you issue the traversing command and check the following:
• The drive coasts to a standstill or is braked and stopped by the mechanical brake.
• No Safety faults and alarms (r0945[0...7], r2122[0...7])
• r9772.17 = 1 (STO selection via terminal - DI CU / EP terminal Motor Module); only rele-
vant for STO via terminal
• r9772.20 = 1 (STO selection via PROFIsafe); only relevant for STO via PROFIsafe
• r9773.0 = r9773.1 = 1 (STO selected and active – drive)
• r9774.0 = r9774.1 = 1 (STO selected and active – group); only relevant for grouping
3.
Deselect STO and check the following:
• No Safety faults and alarms (r0945[0...7], r2122[0...7])
• r9772.17 = 0 (STO deselection via terminals - DI CU / EP terminal Motor Module); only
relevant for STO via terminal
• r9772.20 = 0 (STO deselection via PROFIsafe); only relevant for STO via PROFIsafe
• r9773.0 = r9773.1 = 0 (STO deselected and inactive – drive)
• r9774.0 = r9774.1 = 0 (STO deselected and inactive – group); only relevant for grouping
4.
Run the drive. Check whether the correct drive is operational.
