Configuring a test stop (forced checking procedure)
Test stop
The test stop (forced checking procedure) of the extended functions is a self test of the
inverter that tests its circuits for monitoring the speed and for the safe torque shutdown. A
time block monitors whether the test stop is performed regularly. The test stop is started with
a freely selected signal.
1. Click "Test stop" in the secondary navigation.
2. In the opened screen, use "Test stop selection" to interconnect a signal or a bit of a
control word in order to start the test stop. In the example, digital input DI1 (r722.1) is
interconnected.
3. You can specify the time interval. The permitted maximum value is 8760 hours (one year)
that is normally determined with a risk analysis. Eight hours are entered as default
setting. Alarm A1699 (test stop required) is issued when the time interval expires.
Note
The test stop of the extended functions includes the test of the basic functions (STO).
Consequently, you should set the two timers to the s
ame value.
