Description/comments
Set terminals for "Safe Torque Off (STO)".
Wire terminal "EP" (enable pulses) on the Motor Module.
Control Unit monitoring channel:
•
By appropriately interconnecting BI: p9620 for the individual drives, the following is possi-
ble:
– Selecting/deselecting the STO
– Grouping the terminals for STO
Motor Module monitoring channel:
•
By wiring the "EP" terminal accordingly on the individual Motor Modules, the following is
possible:
– Selecting/deselecting the STO
– Grouping the terminals for STO
Note:
The STO terminals must be grouped identically in both monitoring channels.
Set F-DI changeover tolerance time.
F-DI changeover tolerance time on Control Unit
The parameter is not changed until safety commissioning mode has been exited (i.e. when
•
p0010 ≠ 95 is set).
Due to the different runtimes in the two monitoring channels, an F-DI changeover (e.g.
•
selection/deselection of STO) does not take immediate effect. After an F-DI changeover,
dynamic data is not subject to a data cross-check during this tolerance time.
Debounce time for the fail-safe digital inputs to control STO/SBC/SS1.
Set transition period from STOP F to STOP A.
STOP F is the stop response that is initiated when the data cross-check is violated as a
•
result of fault F01611 or F30611 (SI: Defect in a monitoring channel). STOP F normally
triggers "No stop response".
After the parameterized time has expired, STOP A (immediate safety pulse inhibit) is trig-
•
gered by the fault F01600 or F30600 (SI: STOP A triggered).
The default setting for p9658 is 0 (i.e. STOP F immediately results in STOP A).
Time for carrying out forced dormant error detection and testing the safety switch-off paths.
After this time has expired, the user is requested to test the switch-off paths as a result of
•
alarm A01699 (SI CU: Necessary to test the switch-off signal paths) (i.e. select/deselect
STO).
The commissioning engineer can change the time required for carrying out the forced
•
checking procedure and testing the safety switch-off paths.
Set the new Safety password.
Enter a new password.
Confirm the new password.
The new password is not valid until it has been entered in p9762 and confirmed in p9763.
•
As of now, you must enter the new password in p9761 so that you can change Safety
•
parameters.
Changing the Safety password does not mean that you have to change the checksums.
