Test stop of the TM54F

Test of the fail-safe inputs and outputs
Fail-safe I/O must be tested at defined intervals in order to validate their fail-safety (test stop,
or forced dormant error detection). For this purpose, the TM54F contains a function block
which carries out this forced dormant error detection when selected via a BICO source. To
monitor the time until the next required test, a timer is started after every error-free test stop.
A message is set on expiration of the monitored time and each time the Control Unit is
switched on.
The failsafe digital inputs are always tested during a test stop. Three test stop modes can be
selected for testing the outputs (see following section). After a time interval (p10003) has
expired, the user is notified via message A35014 that a test stop must be performed for the
F-DI/DO of the TM54F.

Function Manual, 05/2010, A5E03264275A
The Safety sampling time corresponds to the sampling time of TM54F.
Note
The Safety clock cycle (p10000) of the TM54F must be set so it is the same as the
monitoring clock cycle in p9300/p9500 for all the drives controlled by the TM54F.
Parameterizing the debounce time of the F-DIs and single-channel DIs of the TM54F.
The debounce time is rounded off to whole ms and then accepted. The debounce time
specifies the maximum time an interference pulse can be present at F-DIs before being
interpreted as a switching operation.
The Extended Functions enter a safety message in a special message buffer upon
detection of internal errors or violations of limits. This alarm must be acknowledged
safely. You can assign an F-DI terminal pair for safe acknowledgment.
Select an input terminal to start the test stop: The test stop is started with a 0/1 signal at
the input terminal and is then only possible if the drive is not in commissioning mode.
Fail-safe I/O must be tested at defined intervals in order to validate their fail-safety (test
stop, or forced dormant error detection). The TM54F module is provided with a function
block which is selected by means of a BICO source to execute this forced dormant error
detection (e.g. switch the L1+ and L2+ sensor power supply). Each selection triggers a
timer in order to monitor the test cycle. A message is set on expiration of the monitored
time.
