(2) When P15.01 is set to 1, the SAFE alarm function is not locked.
As shown in Figure A-15, no alarm locking refers to that after a SAFE fault occurs and the state
is restored, the alarm is automatically deleted. No drive reset is required. The drive executes
the running command again after the external running command is reset.

2. STL1 fault
As shown in Figure A-16, when exceptions occur on the hardware line of safety circuit 1 (that is,
exceptions occur on the running of H1) but H2 signals are normal, the drive enters the safe
operation mode and stops output regardless of the running command. The drive is locked due
to the STL1 alarm, and does not execute the running command again even it receives a reset
command and the external running command is reset.
