The selections including the text 'Rising edge required to start' must be used to exclude the possibility of an unintentional start when, for example,
power is connected, reconnected after a power failure, after a fault reset, after the drive is stopped by Run Enable (Run Enable = False) or when the
control place is changed from I/O control. The Start/Stop contact must be opened before the motor can be started.
