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 Integrated commissioning mode has been exit-
•
ed (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.
