" Safe Stop Commissioning Test
After installation and before first operation, perform a commissioning test of an installation
or application making use of FC 300 Safe Stop.
Moreover, perform the test after each m odification of the installation or application
of which the FC 300 Safe Stop is part.
The commissioning test:
1. Remove the 24 V D C voltage supply to terminal 37 by the interrupt device while the motor is
driven by the FC 302 (i.e. mains supply is not interrupted). The test step is passed if the m otor
reacts with a coast and the mechanical brake (if connected) is activated.
2. Then send Reset sig nal (via Bus, D ig ital 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 c oasting
state, and the mechanical brake (if c onnected) 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 a re passed.
