To parameterize the forced checking procedure (test stop) for the extended functions,
proceed as follows:
1. If the test stop is to be executed during ramp-up, establish a connection for "Execute test
stop automatically during ramp-up". The line in the button must be continuous.
- Or -
If the test stop is not to be executed automatically during ramp-up, select the signal
(p9705) that is to trigger the forced checking procedure. Make sure that the connection
for "Execute test stop automatically during ramp-up" is interrupted.
2. Enter the interval for performing the forced checking procedure and testing the safety
shutdown paths in the "Timer" (p9559) field.
Within the parameterized time, the "STO" function must be selected and deselected at
least once. The monitoring time is reset at every STO deselection.
3. Connect the "Test stop required" (r9773.31) signal sink to a digital output or to a bit in the
status word of the fieldbus.
Status display
The following elements show the current status of the forced checking procedure:
● Time remaining:
Shows the time remaining until the forced checking procedure and the test of the safety
shutdown paths are performed (r9660 for the Basic Functions, r9765 for the Extended
Functions).
● Test stop required:
Shows that a forced checking procedure (test stop) must be performed on the drive.
Evaluate alarm A01699 in your higher-level controller, for example, by connecting
r9773.31 or r9723.0 to a digital output or a bit in the fieldbus status word (r9773.31 for the
Basic Functions, r9723.0 for the Extended Functions).
