Error E1301 appears if STO (Safe Torque Function) is not triggered via two redundant inputs STO A and STO B
simultaneously. It means if STO A and STO B remains at different logic level (ON or OFF) for period greater than
1 second then servo trips on E1301. Precaution is required that both inputs STO A and STO B turned ON or
activated simultaneously without any delay in between them.
