Cause : Safe torque off has been activated during motor run or motor start command has been given when Safe torque off is active. Or: Optional start inhibit hardware logic is activated.

Close Safe torque off switch. If switch is closed
and fault is still active, check power supply at
ASTO board input terminals. Replace ASTO
board.
Or: Check start inhibit circuit (AGPS board)
