The maximum starting rate has been exceeded. No immediate start would be
allowed if the motor stops when this operand is asserted.
The motor stopped after the last allowable start. No restart will be allowed as
long as the operand is asserted (used to inhibit the motor start command).
The maximum starting rate is not exceeded. When stopped, the motor can be
restarted immediately.
