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 possible:
– 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 Integrated 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 failsafe 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 initiates "No stop
response" as default setting.
● After the parameterized time has expired, STOP A (immediate Safety Integrated pulse
inhibit) is triggered 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 checking procedure and testing the Safety Integrated shutdown
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 Integrated shutdown paths.
Setting a new Safety Integrated 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 to change Safety Integrated
parameters.
● Changing the Safety Integrated password does not mean that you have to change the
checksums.
