No. Parameter Description/comments
6 p9620 = "fast DI
on CU"
Terminal "EP"
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.

p9650 = "Value" 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.
8 p9651 = "Value" Debounce time for the fail-safe digital inputs to control STO/SBC/SS1.
9 p9658 = "Value" 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).
10 p9659 = "Value" 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.

p9762 = "Value"
p9763 = "Value"
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.
