Description of Safety Integrated functions
4.2 Safety Integrated Extended Functions
● At the end of the test sequence, the brake is opened or there is a prompt to open the
brake.
● After deselection of the test sequence (test sequence is switched off), another test
sequence can be started, e.g. with a different brake in a different direction, assuming that
the brake test is still selected.
● When the test sequence is active, the brake that is not being tested must remain open.
● After deselection of the SBT, the original speed setpoint takes effect again.
Cancel
A 1/0 edge of signal r10231.1 "Start brake test", interrupts the brake test. The converter
issues alarm A01782 after the brake test has been interrupted. You can then deselect the
brake test using a 1/0 signal edge of signal r10231.0.
Acknowledging alarms
You can only safely acknowledge the alarms relevant for the brake test (Failsafe
Acknowledge, e.g. using TM54F), and under certain circumstances, only acknowledge them
when the brake test is deselected. For "motion monitoring without selection," a POWER ON
is required – or STO/SS1 must be selected/deselected (if extended message
acknowledgment is configured).
