Description: Test mode of the safety output
Using its adjustable test mode, the inverter checks as to whether the safety output can be
shut down.
The test mode is aligned according to the interconnection of the safety output. For test
modes 2 and 3, you must adapt the appropriate wait time to your particular application.
Test mode 2
For test mode 2, the inverter switches off the two outputs one after the other, and evaluates
the feedback via a digital input.
