STL2 fault
As shown in Figure A-17, when exceptions occur on the hardware line of safety circuit 2 (that is,
exceptions occur on the running of H2) but H1 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 STL2 alarm, and does not execute the running command again even it receives a reset
command and the external running command is reset.
