5.7.2 Safe Stop Commissioning Test
After installation and before first operation, perform a commissioning test of an installation or application making use of the FC 200 Safe Stop.
Moreover, perform the test after each modification of the installation or application, which the FC 200 Safe Stop is part of.
The commissioning test:
1. Remove the 24 V DC voltage supply to terminal 37 using the interrupt device while the motor is being run by the FC 202 (i.e., line power supply
is not interrupted). The test step is passed if the motor reacts with a coast and the mechanical brake (if connected) is activated.
2. Then send reset signal (via Bus, Digital I/O or [Reset] key). The test step is passed if the motor remains in the safe stop state, and the mechanical
brake (if connected) remains activated.
3. Then reapply 24 V DC to terminal 37. The test step is passed if the motor remains in the coasted state, and the mechanical brake (if connected)
remains activated.
4. Then send reset signal (via Bus, Digital I/O or [Reset] key). The test step is passed if the motor becomes operational again.
5. The commissioning test is passed if all four test steps are passed.
