o
Give a start command (as per the start source method selected in P1-13) and check that the drive still displays "Inhibit"
and that the operation is in line with the section 4.8.4 "STO",,Operation and 4.8.5 "STO",Status,and,Monitoring

With the motor running normally (from the drive):
o

o
Check,that,the,drive,displays,"InHibit",and,that,the,motor,stops and that the operation is in line with the section 4.8.4
"STO",,Operation and 4.8.5 "STO",Status,and,Monitoring "STO",Function,Maintenance
