Set F- -DI changeover tolerance time
F--DI changeover tolerance time on Control Unit
F--DI changeover tolerance time on Motor Module
S 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 chan-
S
geover (e.g. selection/deselection of STO) does not take place simulta-
neously. After an F--DI changeover, dynamic data is not subject to a cross-
wise data comparison during this tolerance time.
S Both parameters are included in the crosswise data comparison and must,
therefore, be identical. A difference of one safety monitoring clock cycle is
tolerated for the values.
Sets the transition time from STOP F to STOP A
Transition time from STOP F to STOP A on the Control Unit
Transition time from STOP F to STOP A on Motor Module
S The parameters are not changed until safety commissioning mode has
been exited (i.e. when p0010 ≠ 95 is set).
STOP F is the stop response initiated by fault F01611 or F30611 (SI defect
S
in a monitoring channel) when the crosswise data comparison is violated.
STOP F normally initiates "No stop response".
S Once the parameterized time has elapsed, STOP A (immediate safety
pulse cancellation) is initiated by fault F01600 or F30600 (SI STOP A
initiated).
The default setting for p9658 and p9858 is 0, i.e. STOP F immediately
results in STOP A.
S Both parameters are included in the crosswise data comparison and must,
therefore, be identical. A difference of one safety monitoring clock cycle is
tolerated for the values.
Sets the time to carry out the forced checking procedure and testing the
safety shutdown paths
After this time has expired, using alarm A01699 (SI CU: Shutdown paths
S
must be tested), the user is requested to test the shutdown paths
(i.e. select/deselect STO).
S The commissioning engineer can change the time required for carrying out
the forced checking procedure and testing the safety switch--off paths.
Adapt the specified reference checksums
Specified checksum on the Control Unit
Specified checksum on the Motor Module
The current checksums for the Safety parameters that have undergone a
checksum check are displayed as follows:
Actual checksum on the Control Unit:
S
Actual checksum on the Motor Module:
S
By setting the actual checksum in the parameter for the specified checksum,
the commissioning engineer confirms the Safety parameters in each monitoring
channel.
