■Speed feedback exceeded
During direction monitoring, the function monitors whether the speed is within the stop speed of the monitoring direction
specified by the speed feedback. If the time of the speed feedback remains exceeded for the duration set in [Pr. PSA15 Safety
sub-function - Speed detection delay time], the STO function is activated.
