ATTENTION: The user has the ultimate responsibility to
determine which stopping method is best suited to the applica-
tion and will meet applicable standards for operator safety. This
responsibility includes machine risk assessments to identify
hazards associated with “emergency” conditions and the
appropriate system solutions.

ATTENTION: If an electronic malfunction occurs that pre-
vents the drive from responding to the removal of the Drive En-
able input, the motor will continue to operate under power until
the user supplied time delayed dropout relay de-energizes and
opens the Coast to Stop input. If this operation poses an unac-
ceptable risk of personal injury or machine damage, immediate-
ly remove the Coast to Stop input and use an external braking
system to provide rapid stops in an “emergency” situation.
