ATTENTION: Hazard of injury exists due to unintended operation. When
P036 [Start Source] is set to option 3 or option 6, and the Run input is
maintained, the Run inputs do not need to be toggled after a Stop input or a
fault clear for the drive to run again. The drive will stop only when the stop
command is maintained or the drive is faulted.
