Failure test For test purposes, the behavior in the event of a failure of the MC main
computer can be simulated in order to inspect the correct wiring of the holding
brakes. Performing the FAILTEST means:
There are no more software-controlled actions—neither by the NC nor by
the PLC
In HSCI systems, the control-is-ready output –STO.A.G is reset
Enter the code number FAILTEST under MOD.
Acknowledge the message window with the YES soft key in order to carry
out the test.
Hanging axes must be supported before the test in order to prevent
damage to the machine in case of error.
