this parameter is set to zero. The user is responsible for assuring safe
conditions for operating personnel by providing suitable guards, audible
or visual alarms, or other devices to indicate that the drive is operating
at or near zero speed. Failure to observe this precaution could result in
severe bodily injury or loss of life.
