Enable "Safe Stop 1" function.
Enable "SS1" on the Control Unit
Enable "SS1" on the Motor Module
The parameters are not changed until safety commissioning mode has been exited
•
(i.e. when p0010 ≠ 95 is set).
Both parameters are included in the data cross-check and must, therefore, be
•
identical.
The "Safe Stop 1" function is not activated until at least one safety monitoring function
•
has been enabled (i.e. p9601 = p9801 ≠ 0).
Set terminals for "Safe Torque Off (STO)".
Set the signal source for STO on the Control Unit.
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
F-DI changeover tolerance time on Motor Module
The parameters are 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 are not subject to a data cross-check during this tolerance
time.
Both parameters are included in the data cross-check and must, therefore, be
•
identical. A difference of one safety monitoring clock cycle is tolerated for the values.
