Cause : Safe torque off function has been activated
while drive was stopped.
Or: Optional start inhibit hardware logic is
activated.
Close Safe torque off function switch. If switch
is closed and warning is still active, check
power supply at ASTO board input terminals.
Replace ASTO board.
Or: Check start inhibit circuit (AGPS board).
