General information about acceptance tests

Note
Conditions for the acceptance test
As far as possible, the acceptance tests are to be carried out at the maximum possible
machine speed and acceleration rates to determine the maximum braking distances and
braking times that can be expected.
Note
Non-critical alarms
When evaluating the alarm buffer you can tolerate the following alarms:
• A01697 SI Motion: Motion monitoring test required
• A01796 SI Motion CU: Waiting for communication
These alarms occur after every system startup and can be evaluated as non-critical. You do
not need to include these alarms in the acceptance report.

Acceptance test for Safe Torque Off (STO)

No.
Note:
The acceptance test must be individually conducted for each configured control.
The control can be realized via terminals and/or via PROFIsafe.
1. Initial state
Drive in the "Ready" state (p0010 = 0)
•
STO function enabled (onboard terminals / PROFIsafe p9601.0 = 1 and/or p9601.3 = 1)
•
No Safety faults and alarms (r0945[0...7], r2122[0...7]); see note "non-critical alarms" at
•
the beginning of section Acceptance tests".
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.
